The Smith Meter Genesis Meter is a single-case,straight-through type, rotary vane positive displacementmeter. The Genesis Meter is designed with a horizontalshat so it can easily be installed in either horizontal orvertical piping. The accurately-machined housing con-tains a rotor which revolves on ceramic hybrid bearingsand carries two evenly-spaced blades. As liquid owsthrough the meter, the rotor and blades revolve about afxed cam causing the blades to reciprocate. The suc-cessive movement o the blades orms a measuringchamber o precise volume between the two blades,the rotor, the housing, the bottom, and the top covers. Acontinuous series o these closed chambers is producedas the rotor revolves. Neither blades nor rotor contactthe stationary walls o the measuring chamber.

One o the outstanding eatures o the Smith Meter

Genesis Series Meter principle is that the ow transitionssmoothly through the meter while it is being metered.Energy is not wasted by unnecessary hydraulic bendingo the liquid.

Figure 1

Unmeasured liquid (dotted area) is shown entering andcausing the meter rotor and blades to turn counter-clock-wise. Blade paddles B and C are ully retracted whilethe opposite ends, paddles A and D are ully extended,orming the measuring chamber.

Figure 2

Section 1 Principle o Operation

The rotor and blades have made one-eighth revolution.Blade A is ully extended; Blade D is partially drawn back,and the opposite end o blade B is starting to extend.

Figure 3A quarter revolution has been made. Paddles A and Bare ully extended and paddles C and D are retracted. Anexact known volume o new liquid is now in the measuringchamber ormed between paddles A and B.

Figure 4

One-eighth o a revolution later, the measured liquid willthen move out o the meter. Blade A will retract on theoutlet side and paddle C will start to extend which willcapture the next successive measured volume whichwill orm between paddles B and C as the rotor rotates

around the cam.

In one-hal revolutions, two measuring chambers haveormed and the third is orming. This cycle is repeatedas long as liquid ows.

The rotation o the rotor is converted into electronicpulses by means o a magnet that rotates with the rotorand is sensed by a high-resolution hall-eect sensorlocated in the cover. The meter pulse output per unit ovolume (K-actor) is specifed by the customer when themeter is purchased. Once the meter is purchased it isnot possible to change the K-actor value.

Section 2 Installation

1. The meter is a precision instrument and should betreated accordingly. Prior to installation, it shouldbe protected rom adverse weather conditions andaccidental abuse.

2. Adequate pipe support must be provided close tothe meter because the meter is supported by the

anges. Piping must not produce an undue strainon the meter.

Dimensional outline drawings o the meter are avail-able.

3. When installing the meter, a carpenter's level shouldbe used on a at surace o the meter housing (orexample on the cover on the nameplate pad) toensure the rotor is level.

This is important because the meter shat mustbe level.

4. When installing the meter, be sure the drain plug isaccessible but that the meter cannot be accidentallydrained o product.

WARNING!Thermal Pressure

Thermal expansion of liquid in this equipment cancause high pressure damage. A Thermal PressureRelief Valve may be necessary in the system.

5. Protect the meter and system against the eects othermal expansion with a relie valve.

6. Where necessary, a deaerator or air eliminator shouldbe installed to keep air and vapor out o the meter.

7. All piping should be internally cleaned beore themeter is put into operation.

Rust, dirt, welding shot, and other oreign materialmust be removed completely.

Remove the meter and install a spool piece i thesystem is to be pressure-tested with water or idebris is to be ushed rom the system.

The meter should be protected by at least a 40-meshstrainer.

8. Where necessary, a ow-limiting valve should beinstalled downstream o the meter to protect it romexcessive ow rates.

9. Do not calibrate with water or allow water to standin the meter.

10. Flush the meter with a light lubricating oil i it is letidle or stored.

11. The meter can measure ow in either direction(orward and reverse).

For standard and reverse ow directions, see meterarrangements on page 5.

Wire Connections

To ensure proper opera-tion and to avoid damage

to the circuitry, check tomake sure that all S1dip switches arelocked in the "OFF"position (closestto the terminalblock).

Numbering and labelfor the connections canbe located on the PCBand terminal block.

Section 2 Installation

The HRE circuit board (Hall Rotary Encoder) takes therotation o the magnetically coupled PD meter and elec-tronically senses the rotation to produce output pulses.The encoder is completely isolated rom the product andmeter internals. Because the encoder and rotor rotationare magnetically coupled, no gear train or thrust bearingmaintenance is needed.

Upon installation, be sure that all our screws that holdthe HRE board are ully seated and the board is fxedat and centered on the standos in the junction box.

Section 3 Operation

Arrangement

Start-Up Procedure

When the meter is frst installed in the line there is air inside

the rotor. The air takes some time to work out. I the meteris subjected to hydraulic shock during this vulnerable time,the rotor can pinch down on the blades and cause bladebreakage or cam shat rotation. By ollowing the procedurelisted below, the likelihood o meter damage will be greatlyreduced.

1. I possible, gravity head should be used to initially fll themeter as air is vented rom a high-point vent.

2. Close the upstream isolation valve and energize the pump.

3. Slowly open the upstream isolation valve until the meterand ow control valve arejustpressurized. It is importantthat the upstream valve be just barely open to ensure thatthe meter will be operated at very low ow.

4. Initiate low ow (reer to meter specifcations) via the

electronic preset.5. Vent air rom the high-point vent until there is no sign o air

being vented (30 seconds or more). REMEMBER air istrapped inside the rotor and takes time to be displaced.

6. Gradually open the isolation valve and initiate normaloperation.

This procedure should be used whenever air has beenintroduced to the line or meter.

General Operating Inormation

1. The meter was tested with kerosene; the K-actor (pulses/

unit o registration) will be indicated on the meter tag. (Me-ter specifc compensation actors are preloaded into theelectronics, based on user specifc viscosity ranges).

2. To obtain maximum service rom FMC Technologies, itis suggested that detailed records be maintained.

Data such as model, serial number, operating rate, type oproduct, meter clearances, totalizer readings, meter ac-tor, and other pertinent inormation should be recorded.Such inormation is an excellent guide in scheduling apreventive maintenance program.
