Introduction

Scope of application The TRZ 03-TE and TRZ 03-TEL turbine meters are flow meters which can be used for custody transfer metering. Unlike these instruments, the TERZ 94 turbine meter can only be used for secondary metering. All three types of turbine meters measure the quantity of gas flowing through them in units of volume at prevailing pressure and temperature. Therefore, the units of volume are determined at flowing conditions. The volume of the gas flowing through and the flow rate are indicated by a mechanical totalizer in cubic meters at flowing conditions or m3/h respectively. In addition, the turbine meters can be fitted with HF or LF pulse transmitters and with reed contacts. In this way, pulses are obtained whose number is proportional to the volume which has flowed through. These pulses can be further processed by volume correctors. The major differences between types TRZ 03-TE, TRZ 03-TEL or TERZ 94 are as follows: TRZ 03-TE

Approved for custody transfer metering in compliance with DIN 33800. Installation length: 3 x DN Accuracy 0.5% (above 0.2 Qmax) 2-channel measurement

TRZ 03-TEL

Approved for custody transfer metering in compliance with TR G13 / OIML. Requires no additional inlet pipe even in the case of heavy flow disturbances. Accuracy 0.5% (above 0.2 Qmax) 2-channel measurement

TERZ 94

For secondary metering. Installation length: 1.5 x DN Accuracy 1% (above 0.2 Qmax)

The following applies to all meter types:

Maximum operating pressure: 100 bar (not for gas meters with a plastic turbine wheel) Meter sizes from G 40 to G 16000 Measuring range 1:20; 1:30 or 1:50 (see data sheets) Connections in compliance with DIN or ANSI are available. Special designs for aggressive gases are available. Available for low temperatures (< 10°C) All gas meters can be operated in any position up to the nominal diameter of DN 200.

Method of operation The method of operation of the electronic turbine meter is based on the measurement of the gas velocity. The velocity of the gas flowing through the gas meter is increased in the flow straightener and the gas strikes the turbine wheel in a defined flow cross section. In the flow straightener, unwanted vortices, turbulences and asymmetries are removed or reduced. The turbine wheel is mounted axially, while the blades of the turbine wheel are arranged at a certain angle to the gas flow. Within the measuring range (Qmin - Qmax), the rotational speed of the turbine wheel is almost proportional to the mean gas velocity and, therefore, to the rate of flow. The number of rotations is a measure of the volume that has flowed through. Two pulse-wire sensors pick up the rotational frequency of the turbine wheel by a non-contact measurement. For this purpose a permanent magnet is fixed at the end disc of the turbine shaft which induces one voltage pulse per rotation. These pulses are further processed by the electronic system of the meter head.

Meter head Inside the meter head, the number of pulses is divided by the meter factor (number of pulses per m3) and the result is used to calculate the volume at measurement conditions. In the main totalizer, the sum of the volume at measurement conditions with flowed through the meter per time unit on the flow rate display.

At the HF output, the unchanged signal frequency of the sensor element is outputted, whereas, for the LF output, this HF frequency can be reduced by one programmable scaling factor.

Approvals Types TRZ 03-TE and TRZ 03-TEL has been approved for custody transfer metering.

The following approvals have been obtained: German approval No. 7.211/02.13 DVGW registration No. CE-0085BN0291

Standards / Guidelines All RMG turbine meters have passed the disturbance measurements in compliance with OIML Recommendation IR-32/89, Annex A, with slight and heavy flow disturbances. Therefore, this meter design meets the requirements for installation in compliance with Technical Guideline G 131), Sec. 1. Test specifications are as laid down in PTB Testing Instructions, Vol. 4, Volume gas meters, 2nd revised edition of 1992.

The RMG turbine meters of type TRZ 03-TE and TRZ 03-TEL comply with DIN 33800.

Validity of meter proving The turbine meters of type TRZ 03 which are suitable for custody transfer metering must be subjected to subsequent meter proving at regular intervals. The validity of meter proving is determined in the German Metering and Calibration Rules issued in 1988 (with amendment of September 24,1992) and extends to five years for electronic turbine meters without a lubricator.

Note: these periods are valid for Germany, in other countries the periods are normally different!

In the case of subsequent meter proving, the gas meter must be removed and tested on a test rig.

Measuring ranges The measuring ranges are between 10 and 25,000 m3/h (flowing conditions). A measuring range is specified for each meter size. It is limited by the minimum flow rate Qmin and the maximum flow rate Qmax (see tables on pages 55 to 56).

For types TRZ 03-TE and TRZ 03-TEL, this is the flow range where the gas meter must indicate correct values within the error limits specified by the German Metering and Calibration Rules.

Turbine meters of type TRZ 03-TE have measuring ranges up to 1:30 even under atmospheric pressure. If a high-pressure test is conducted in compliance with Technical Guideline G 71) (PTB), the measuring range can be extended to 1:50. Then the minimum flow rate Qmin HP is the lowest test point during high-pressure testing. Types TRZ 03-TE and TRZ 03-TEL may then be used for billing purposes within the specified HP flow and density ranges.

Extension of the measuring range In the range of 0.2 Qmax to Qmax, the measuring behaviour of turbine meters is determined by the aerodynamic conditions in the flow channel and the measuring cross section. By means of many series of tests conducted both under atmospheric pressure and under higher pressures and with an appropriate rating for such ranges, it is possible to achieve a deviation of the calibration curve under atmospheric conditions and under high-pressure conditions of < 0.5% in the flow range of 0.2 Qmax to Qmax. In the lower flow range, the measuring behaviour is determined by the relationship between the gas flow driving the measuring wheel and the slowing-down torques due to drags (bearings and totalizer). The driving torques increase linearly with the density and quadratically with the velocity of the gas to be measured. Due to the physical conditions, the measuring range is therefore enlarged in relation to the density. The lower flow limit shifts in the direction of smaller loads.

Use the formula below as approximate equation:

)h/m(2.1

QQ 3minmfl

The density can be determined with the following approximate formula:

Installation and Commissioning

Installation Caution: Please read these installation instructions through and make sure that you have under-stood the procedure before you start to install the RMG turbine meter or put it into operation. Turbine meters are precise measuring instruments and must be handled carefully during transport, storage and operation. When you install the turbine meter, please observe the direction of flow indicated by an arrow on the meter case.

Installation errors may cause physical injuries or result in the destruction of the turbine meter.

It is essential to follow the instructions below:

Remove the yellow protective film at the flanges completely. Rests of this plastic film affect the flow profile and cause measuring errors!

The RMG TRZ 03-TE, TRZ 03-TEL and TERZ 94 turbine meters can be operated in any position up to the nominal diameter of DN 200. From the nominal diameter of DN 250, however, only a horizontal direction of flow is possible. If a particular position was indicated when ordering the turbine meter, you must install the turbine meter in this position. In addition, you must make sure that the filling opening of the lubricator faces upwards.

Any components affecting the gas flow must be avoided directly upstream of the turbine meter (see DVGW Guideline G 492 II1) and PTB Guideline G 132), exception: TRZ 03-TEL).

An inlet pipe of a minimum of 2 x DN is required upstream of the RMG TRZ 03-TE turbine meter. The inlet pipe must be designed as a straight pipe section of the same nominal diameter as the gas meter. If there is a heavy flow disturbance, it is necessary to use flow straighteners (see table on next page). A pipe or fitting (bend) of the same nominal diameter as the gas meter and an overall length of 2 x DN must be installed downstream of the gas meter. Temperature measuring instruments may only be installed at a distance of 1 x DN or in the case of nominal diameters of DN 300 at a minimum distance of 300 mm. If there are flow disturbances (e.g. due to a gas pressure regulator) upstream of the inlet pipe, it is also necessary to use a perforated-plate straightener. You can use perforated-plate straighteners complying with ISO 5167-1 or of type RMG LP-35, the latter resulting in a pressure loss which is 2.5 times lower than that of the standardized flow straightener.

1) can be ordered at DVGW, Josef-Wirmer-Str. 1-3, D-53123 Bonn (www.dvgw.de) 2) can be ordered at PTB, Bundesallee 100, D-38116 Braunschweig (www.ptb.de)

Upstream of the RMG TRZ 03-TEL turbine meter, no inlet pipe is required, even in the case of

heavy flow disturbances such as those caused by a gas pressure regulator. It has been tested without an inlet pipe in compliance with Technical Guideline G13 (which corresponds to the OIML Guideline IR-32/89). A pipe or fitting (bend) of the same nominal diameter as the gas meter and an overall length of 2 x DN must be installed downstream of the gas meter. Temperature measuring instruments may only be installed at a distance of 1 x DN or in the case of nominal diameters of DN 300 at a minimum distance of 300 mm.

The opening angle of reducers or expansion fittings installed upstream of a turbine meter of

type TRZ 03-TE, TRZ 03-TEL or TERZ 94 must not exceed 30°.

In order to obtain precise measurement results, the turbine meter must be installed in the gas line in such a way that no seals protrude from the flanges into the pipeline.

A protective screen should be installed on the intake side of the gas meter to protect the turbine meter against any foreign particles possibly contained in the gas flow. The protective screen can be a perforated plate of sheet metal with a hole diameter of 3 mm which is available from RMG.

The pr tap which is located on the RMG turbine meter is the pressure-measuring point which was used for taking the relevant pressure at measurement conditions during meter proving. This pressure-measuring point is used for connecting pressure-measuring instruments such as flow computers or volume correctors. Other connection options (e.g. for temperature measurement) can be supplied on a pipe section on the output side of the gas meter.

Caution: Protect the turbine meter from damage caused by heavy flow variations, e.g. if the downstream pipeline system must be filled or blown off.

Caution: If it is necessary to do welding work on the gas line, such work can only be performed at a safe distance from the gas meter. Extreme temperatures prevailing in the gas line in the proximity of the gas meter can result in a permanent damage to the gas meter.

Caution: All electrical connections between the gas meter and the amplifiers or the flow computer must be carried out in compliance with the installation instructions. Make sure that these connections are intrinsically safe.

Caution: Any liquids remaining in the gas line after hydrostatic testing can damage the interior parts of the gas meter. If hydrostatic testing is necessary, the turbine meter must be replaced by a pipe section. Make sure that no liquid remains in the gas line upstream of the gas meter after hydrostatic testing.

Operating data

Recommended threshold values for maximum service life and maximum accuracy:

Maximum overload: < 20% above Qmax, for a short time (< 30 sec)Maximum flow changes or shock loads

< 0.01·Qmax/sec ̂ 1% of Qmax/sec e.g. starting up 0 to 100%: > 100 sec

Maximum pressure change: < 0.1 bar/sec Maximum flow pulsation: < 5% Particle size in the gas flow: < 5 mm Lubrication of bearings: See chapter on “Lubrication”.

Lubrication intervals depend on the condition of the gas (condensate, rust or dust).

Vibration / mechanical shock: < 1 mm/sec (vibration velocity) These specified data must be determined and checked during commissioning, prior to filling and during the start-up and running-in phases of the gas meters. If more than one threshold value occurs at the same time, appropriate action must be taken in the station to improve the measuring conditions. The operator must record all measuring data (gas meter and operating data) during the whole period of operation in order to detect the causes of a possible destruction of the gas meter at an early stage and take corrective action in good time.

You can install the meter head also vertically. To do this, you must proceed as follows:

Unscrew the cover of the meter head. Disconnect the two wires from terminal X5 (remember the polarity!). Unscrew the fastening screws of the meter board.Remove the board carefully from the case. If

necessary, disconnect the two wires from the button. Loosen the set screw (2). Now you can remove the case of the meter head and an aluminium

assembly part will appear. On the side of the case, there is a hole which is covered with a screw. Mount the retainer part

to this hole and close the hole in the rear panel by means of the screw. Thread the signal wires through the retainer part, place the meter head onto the turbine case,

turn it into the desired position and retighten the set screw (2). Insert the board again into the case, connect the signal wires again to terminal X5 (make sure

that the polarity is correct!) and screw on the cover again.

Power Supply Depending on the type of the device, there are different options of power supply.

1. The basic TRZ 03-TE model is supplied by an internal lithium battery which enables to operate the device continuously for a period of approx. six years. This, however, is conditional on the device being read once a week or “woken up” by pressing the external button.

2. If an interface module is used for transmitting data, such as the ENCO with external supply, the service life of the battery is more than 10 years.

3. The TRZ 03-TE / TEL (current transmitter) is completely supplied through a current loop. If pulse processing is to be maintained even in the case of a power failure of the current loop, a standby battery (available as an option) should be installed which will bridge the power supply during a period of up to 6 months.

Electrical connections The LF and HF volume pulses and the alarm output are led out of the meter head by a 7-pin connector (Binder). All other connections have to be made at the terminals on the board. Standard connection battery version and mains powered version:

The supply/current-loop (mains powered version only) is connected to the terminals X22 on the transmitter board TERZ94trm.

In areas subject to explosion hazards, the TRZ 03-TE / TEL must only be connected to certified intrinsically safe circuits.

Make sure that the limiting values from the conformity certificate (see appendix) for the devices, which have to be connected, are not exceeded.

If one or more electric circuits are used, it is to ensure that with the cable selection the permissible limiting values according to the EEC design inspection certificate are not exceeded.

Each ex signal circuit has to be wired in its own cable, which is to be led through the appropriate cable gland.

A fixed installation of the intrinsically safe cables is mandatory.

The connecting cables have to be provided with core-end sleeves. To reach the electrical connections on the board, you must first remove the cover of the meter head.

To convert from the meter head directly mounted on the meter case to the remote totalizing unit and vice versa it is necessary to change the positions of some jumpers (see inputs and outputs in the annex).

Battery powered version: Controlling the start-stop totalizer or resetting the resettable totalizer (depending on the programming of the electronic totalizing unit) is performed through input X5 terminals 1 and 2. As soon as input X5 terminals 1 / 2 has been short-circuited through an external contact, interruption or resetting is performed.

For this purpose, set jumpers at the positions identified with XS 2 to the “reed contact” function.

Mains powered version: In the case of the TERZ 94-S, terminal X22 (on current module TERZ94trm) is used as current-loop connection to supply the device and as output current (4-20 mA). To connect cables to the spring terminals, you need a screwdriver with a blade width of a maximum of 2.5 mm. Introduce the blade into the intended slot and press down the screwdriver to open the spring terminal. Earthing

To prevent measuring errors caused by electromagnetic interference, you must not fail to earth the case of the meter head via the earthing screw on the left side of the case.

Thereby make sure that you have an electrical link between TERZ 94 and the piping, as it is shown in the drawing below.

Minimum cable cross section: up to a length of 10 m: 6 mm2 from a length of 10 m: 10 mm2

Cables

Use 2-core or multicore shielded cables which are twisted together in pairs (type LIYCY) for the signal lines (LF output, HF output, current-loop connection, control input). The shielding must always be connected to earth on both sides. In the case of the battery powered version, you must proceed as described in the chapter “Cable glands”. We recommend that cable cross sections between 0.25 mm2 and 0.5 mm2 are used. Due to the cable gland, the outside diameter must be between 4.5 mm and 6.5 mm.

When the device is used in areas subject to explosion hazards, the maximum cable length is limited by the limit values for intrinsically safe circuits and depends on the inductance and capacitance of the cable!

In particular: The maximum cable length between the TRZ 03-TE and the transmitter supply unit of type KFD2-STC3-Ex1, in connection with the cable type LiYCY 2 x 0.75 mm2, is 250 m for the current output. You can also use other cable types, if the following cable values are not exceeded: Capacitance < 200 nF/km inductance < 1 mH/km

Cable glands

Clamp the shielding on both sides, as shown in the picture below, into the cable glands located on the outside of the case:

Unscrew the cap nut. Pull out the plastic clamping piece. Push the cable end through the cap nut and the clamping piece and bend the shielding

backwards. Put the clamping piece back into the connecting piece. Screw on the cap nut again.

If your TRZ 03-TE is designed for remote totalizing, you can install the totalizing unit at a distance of up to 50 m from the meter case. Usually, the cable has already been connected to the totalizing unit when the TERZ 94 is delivered. Should this not be the case, you will have to connect the connecting cable to Input-terminal X5, clamp S1+ and clamp S1- of the board. For 2-channel meters connect the second sensor to the clamps S2+ and S2-. Use only shielded cables of the type:

LIYCY - 2 x 0.75 blue (1-channel version) LIYCY - 2 x 2 x 0.75 blue (standard) Maximum cable length: 50 m Furthermore, you must check the plug-in jumpers XS1, XS2 and XTERZ90 on the display board. Settings at XS1 and XS2: jumpers 3-4

Temperature measurement In order to measure the gas temperature, a resistance thermometer can be used in a thermowell in a fitting downstream of the gas meter. It is recommended that a second thermowell, e.g. for a monitoring thermometer, be used. If such thermowells are not provided for in the meter case, temperature measurement must be performed at a distance of up to 3 x DN or a maximum of 600 mm downstream of the turbine meter. All turbine meters of types TRZ 03-TE and TRZ 03-TEL from the nominal diameter of DN 80 (3") upwards can be fitted with a thermowell for a PT100 resistance thermometer. Due to their short size, turbine meters of type TERZ 94 cannot be fitted with a thermowell. Operating temperatures prevailing at outdoor metering stations in winter or at natural gas metering stations downstream of regulating stations are usually in the range of -5C to +10C. By comparison, higher operating temperatures prevail at metering stations located downstream of compressor stations. For this reason, the measuring elements of the temperature sensors located outside the gas line must be appropriately insulated against the weather. In order to achieve optimum thermal conduction, oil as a heat transfer liquid should be filled in the thermowells in any case.

COMMISSIONING ............................................................................................................................... ................................................................................

............................................................................................................................... ................................................................................ Manual TRZ 03-TE · EN06 · 2013-03

26

Commissioning

Filling with oil When the turbine meters are delivered, the lubricators do not contain any oil. The oil pumps must not be filled with oil until they are at the installation site prior to commissioning! A small bottle of oil is supplied with each gas meter. For detailed lubrication instructions, see chapter “Lubrication” from page 40.

Connecting the gas flow

Do not fill any downstream pipelines or station sections through the turbine meter. This may speed up the turbine wheel and lead to excessively high loads with resultant damage.

Short-time overload operation of 20% above the maximum flow rate Qmax is permissible. Such load conditions should be avoided, however, since in most cases they cannot be controlled and exceed the officially approved limits for custody transfer metering. Moreover, such overloads reduce the service life of the gas meter. The gas flow must be free of foreign particles, dust or liquids. Otherwise it is recommended that filters or separators be installed. Before starting up the device, make sure that all lines have been correctly installed and connected in the terminal compartment. The case must be completely closed.

Initializing the totalizing unit When you start up the device for the first time, set the totalizing unit in the desired condition. Check the programming of the pulse width, the LF pulse scaler, etc. Mains powered version: Check the programming of the current output mode. Note: All parameters can only be changed after the cover of the meter has been removed.

Principle of programming

For programming, you must always proceed as follows:

First change over to the display value to be modified. To do this, press either the control button (only forwards) or the internal buttons “+” and “-” or the external buttons “” and “” (forwards and

backwards).

Change to programming mode by pressing “P” for at least 2 seconds. On the left side of the display, a flashing character or cursor will appear. If necessary press the “” key so many times until a flashing character appears.

0 1 2 3.2 3 P/m3

You can now modify the flashing decimal by pressing either “+”or “” (+1) or “-” or “” (-1). Example: If you press the ““ button three times, the first decimal will be increased from 0 to 3. If an “L” appears on the far left side of the display, this value is a list. With a list, you can only scroll in the specified values.

After you have completed your programming of the first decimal, press “” once and the next character will start to flash. Now proceed with your programming until you have reached the last decimal place.

Then you must press “” once again to have the set value accepted and quit programming mode.

Press the “P“ button to set the decimal point behind the flashing digit. With totalizers, modes and integers, no decimal point is permitted.

Press the control button if you have made an error or if you want to discontinue inputting data.

Display values

Measured values, such as flow rate, frequency, etc. are display values and cannot be directly modified. However, there are many parameters which influence the formation of these measured values. These parameters are described in the following section. Examples of display values: flow rate, version number, year of construction, serial number, value of the current output in mA, etc.

Configuration

The basic configuration of the TRZ 03-TE / TEL is implemented via an 8-character display value (A08). This “TERZ mode” defines the operating mode of the device. Some parameters require a specific hardware or hardware configuration. NOTE! Hardware and software configurations must coincide. Any modifications of these parameters can cause malfunctions. Let’s start on the left side of the display: (operating alignment italic) Internal parameters

For testing and diagnostics (no influence on the metering result). 0: Menu for standard operation. 1: Menu for service 9: All parameters visible.

Main totalizer mode

This parameter defines the unit for the gas volume 0: m3 (cubic meter). 1: cf (cubic foot).

LF pulse width

The LF pulse width can be set at 125 ms or 250 ms. 0: 125 ms 1: 250 ms

Cut-off time of the display

A few minutes after you have operated the device for the last time, the display will switch off to expand the service life of the battery of the TRZ 03-TE / TEL. There are the following times for selection:

Pulse comparator

The 2-channel version of the TERZ-94 (TRZ03 TE / TEL) provides for pulse monitoring. Pulse monitoring requires two input pulses which are out of phase. If a pulse occurs at the same time on channel 1 and channel 2, a fault counter is increased. If there is a missing pulse on one of the two channels, a fault counter is increased, too. If this fault counter reaches the value X(A10) before Y(A11) undisturbed pulses have entered one of the two channels, a fault will be outputted. This fault will not be erased until Y undisturbed pulses have been counted. Flow rate at 4 mA

With this parameter, you set the flow rate (in m3/h) which corresponds to an outputted current of 4 mA. Generally, the minimum flow rate Qmin of the meter is set here. (This setting is made in the factory.) Flow rate at 20 mA

With this parameter, you set the flow rate (in m3/h) which corresponds to an outputted current of 20 mA. Generally, the maximum flow rate Qmax of the meter is set here. (This setting is made in the factory.) Then the current which will be outputted for flow rates within the programmed limits will be between 4 and 20 mA and results from linear conversion. Current default value (calibration current)

With this parameter, you set the value of the calibration current. A constant calibration current is outputted if the current output mode parameter is set to default. The value of the calibration current must be within the following limits:

Minimum value: 4 mA Maximum value: 20 mA

Current output mode

Here you define the measured or default value which is to be outputted. 0: Default value (see above) 1: Flow rate Qm All other values are not permitted! Current damping

Here you define how the current output is to be damped. Permissible values for D are 0 to 0.9 ! Output current = (1-D) x value + D x old value Correction factors for current offset and current rise

The current output is adjusted in the factory through two correction factors (offset and rise). In the event that a recalibration should really be necessary, there is a PC-based program available which will define the new offset and rise values for you.

Influences on the error of measurement due to operation

Intermittent operation

Rapid changes of the gas flow should be avoided, since the turbine wheel can follow these changes only with a certain delay due to its inertia. In this way, errors of measurement occur, in particular, if the gas flow is shut off. Since in this case the turbine wheel slows down after the flow has stopped, a gas volume is measured which is always higher than that which has actually flowed through the gas meter. In the supplement to PTB Guideline G 13, an instrument is stipulated which records the flow during the slow-down time of the turbine wheel for intermittent operation (i.e. if the gas flow is permanently switched on and shut off). If control signals of a shut-off valve are available, this volume can be recorded for custody transfer metering purposes for example by the TAZ 9, an RMG device recording the gas volume during the slow-down time of turbine meters after flow stop (for custody transfer metering only in conjunction with the TRZ 03-TE or TRZ 03-TEL). As soon as the shut-off valve is closed, the TAZ 9 starts to record the gas volume during the slow-down time of the turbine meter.

Influence of pulsations

The gas flow must be free of shocks or pulsations. A gas metering station can be affected by flow pulsations, however, if the following equipment has been installed upstream or downstream in the system:

reciprocating piston compressors, rotary displacement meters, gas pressure regulators lacking steadiness of operation, pipes where no gas flows (siphons). Volume flow pulsation is the decisive quantity for evaluating the performance of gas meters under the influence of pulsations. Volume flow pulsation is physically always associated with pressure variations. The following relation is established in a first approximation:

Q pDN

QKrel rel

2

where:

Q̂rel: is the relative volume flow pulsation (peak-to-peak)

Q̄: is the mean volumetric flow

p̂rel: is the relative pressure pulsation (peak-to-peak) DN: is the nominal diameter of the gas meter K: is a constant depending on standard density, velocity of sound, compressibility, pressure at

base conditions, temperature, and station-specific parameters.

OPERATION ............................................................................................................................... ................................................................................

............................................................................................................................... ................................................................................ Manual TRZ 03-TE · EN06 · 2013-03

39

With this relation, it is possible to estimate volume flow pulsation on the basis of pressure pulsation, which can be measured more easily. Direct measurement of volume flow pulsation is preferable, however, since the results are more reliable. The crucial factor is the pulsation at the location of measurement.

Consequences

In the case of pulsating flow, the turbine meter shows a measured value which is too high. Due to the pulse applied by the flow on the impeller which increases quadratically with the flow velocity, the resultant rotational speed is higher than the mean value of the flow velocity. The influence with high gas density is less, but increases with a high mass moment of inertia (heavy impeller) or fast-running wheels. Furthermore, high pulsation amplitudes may result in premature wear of shaft bearings due to increased load.

Limiting values

Frequency ranges It is generally unlikely that measured values will be distorted in the frequency range above

100 Hz. In practice, it is hardly possible to initiate any significant flow variations at such frequencies. Disturbances are to be expected most frequently in the frequency range between 0.1 Hz and

100 Hz, since with typical station dimensions, the gas column can be expected to produce resonances. Flow variations with a high relative amplitude may occur.

In the frequency range below 0.1 Hz, there is a quasi-steady flow which will not cause any distortion with the gas meters.

Pulsation amplitudes

Studies have shown that no disturbances are to be expected in the case of relative flow pulsations below 5% (peak-to-peak) and relative pressure pulsations of less than 0.1% to 0.5% (peak-to-peak). These data should be regarded as approximate values depending on the flow rate and pulsation frequency involved.

Specification for lubricating oils For lubrication purposes, we recommend that you use only Shell Tellus S2 MA 10 or another lubricating oil with 2 to 4°E at 25°C complying with MIL-L-6085-A in order to avoid damage to the shaft bearings. You can order your supply of lubricating oil from us in 1-liter containers under Ref. No. 82.11.148.00. Shelf life of oil: the shelf life depends on the operating conditions (e.g. UV light, humidity etc.). In principle the oil suffers no quality loss during the first 3-4 years. Initial lubrication When the turbine meters are delivered, the lubricators do not contain any oil. The oil pumps must not be filled with oil until they are at the installation site prior to commissioning. A small bottle of oil is supplied with each gas meter. For the initial lubrication more pump strokes are necessary than for the relubrications because first the oil pipes have to be filled with oil.

Relubrication

The relubrication intervals are stated on a indicating plate on the meter case. See also “Lubrication procedure”. Example:

In the case of unfavourable operating conditions, such as condensate forming because of water or hydrocarbon, or dust-laden gas, or service temperatures above 50°C, we recommend that lubrication be performed at shorter intervals, even daily under extreme conditions (permanent formation of condensate).

If the gas meter is operated under the above-mentioned conditions, it is likely that its service life will be reduced. If you have questions to the relubrication in such cases please contact RMG. Lubrication procedure

To fill the pumps and lubricate the turbine meters, proceed as follows: Oil gun

To fill with oil: 1. Unscrew cover. 2. Pull piston by means of the chain. 3. Fill with oil. 4. Reinsert piston by pushing it as far as

possible. 5. Screw on cover again tightly. 6. Vent the oil gun! To lubricate: 1. Plug oil gun onto oil nipple. 2. Depress oil gun towards oil nipple

once for each stroke.

Changing the battery For the battery version use only lithium batteries of the type SL 770/P Size C, 3.6 V produced by Sonnenschein or type LS 33600 produced by Saft.

These batteries have a service life of approx. 6 years and can be ordered ready for installation from RMG under the following order number:

For Ex and Non-Ex devices: 207626 Emergency battery for version with external supply: 207658

If you use other batteries than the replacement batteries from RMG, you run the

risk of the TRZ 03-TE / TEL not being approved for areas subject to explosion hazards any more.

In areas subject to explosion hazards, you must never insert or remove the battery. Remove the display board from the case and change the battery in an area without explosion hazards.

To change the battery, you must proceed as follows:

Remove the cover of the meter head – on the rear side, there is the battery fixed with cable ties. If the meter is located in an area subject to explosion hazards, disconnect the sensor wires from

terminal X5 (see chapter “Electrical connections” – Remember the terminals and colours!) and take the display board to an area without explosion hazards.

Remove the connecting wires of the battery from the contacts on the bottom of the terminal board.

Screw off the four screws with witch the battery board is fixed. Remove the cable ties with which the battery is fixed and take out the battery. Insert the new battery and fix it with cable ties. Plug the connecting wires of the battery on the contacts of the terminal board. Make sure that

the polarity is correct. Reinsert the battery-board into the case and screw it on. In case you have previously

disconnected the wires of the sensor and the control button, you must connect them again (make sure that the polarity of the sensor wires is correct!).

Close the case.

Maintenance instructions RMG turbine meters are maintenance-free except that they require lubrication and change of battery at regular intervals. Since all gas meters fitted with oil pumps are shipped with an empty oil storage tank, it is absolutely essential to fill the storage tank of the oil pump with oil and perform lubrication before the gas meter is put into service.

The operator should nevertheless check the turbine meter at regular intervals. In this connection, please refer also to DVGW code of practice G 495. (Gas pressure regulators for monitoring and servicing large-scale gas metering systems)

The gas meter should be checked for accuracy approximately every two years depending on whether it is possible or necessary to perform such checks. This can be done as follows: In the station itself by connecting two gas meters in series. In an officially acknowledged testing laboratory for gas measuring instruments. In the factory.

Labelling All important data which are necessary for operating the gas meter are stated on the plates which are affixed to the meter case, totalizer or pulse transmitters.

Converting the TRZ 03-TE/TEL into the version with external supply and current output The battery powered version can be converted into the mains powered version by installing another board. Remove the battery (see chapter “Changing the battery”). Remove the jumper for battery-powered mode (1-2) on the socket X2_0 of the board. Srew the 4 short stay bolts onto the present stay bolts on the board. Plug the current module TERZ94trm with a 12-pin connector (X2_1) into the socket X2_0. Apply the supply voltage (24V) to terminal X22 (1 +, 2 - ). Switch on the power supply (24 V). Check the current output:

Set the current output in channel A08 to I-Out (mode 1 or 2). Channel C02: enter flow rate at 4 mA. Channel C03: enter flow rate at 20 mA. Set channel C04 (default value) to 10.0 mA. Set channel C05 (output mode) to 1 (current output is proportional to the flow rate). Channel C06: enter correction value for the current offset (see value on the board) Channel C07: enter correction value for the current rise (see value on the board) In the event that a recalibration should be necessary, there is a PC-based program available

which will define the new offset and rise values. Now the mains powered version is operational.
