Function

Measurement PrincipleIn order to measure the flow of a medium in a pipe, ultrasonic signals are used, employing the transit time dif-ference principle. Ultrasonic signals are emitted by a transducer installed on the pipe and received by a sec-ond transducer. These signals are emitted alternately in the flow direction and against it.As the medium in which the signals propagate is flowing, the transit time of the ultrasonic signals in the flowdirection is shorter than against the flow direction.The transit time difference, Δt, is measured and allows the flowmeter to determine the average flow velocityalong the propagation path of the ultrasonic signals. A flow profile correction is then performed in order to ob-tain the area averaged flow velocity, which is proportional to the volumetric flow rate.Two integrated microprocessors control the entire measuring process. This allows the flowmeter to removedisturbance signals, and to check each received ultrasonic wave for its validity which reduces noise.

Calculation of Volumetric Flow Rate

= kRe . A . ka . Δt/(2 . tfl)where

Number of Sound PathsThe number of sound paths is the number of transits of the ultrasonic signal through the medium in the pipe.Depending on the number of sound paths, the following methods of installation exist:• reflect mode

The number of sound paths is even. Both of the transducers are mounted on the same side of the pipe. Correct positioning of the transducers is easier.

• diagonal modeThe number of sound paths is odd. Both of the transducers are mounted on opposite sides of the pipe.

• direct modeDiagonal mode with 1 sound path. This should be used in the case of a high signal attenuation by the medi-um, pipe or coatings.

The preferred method of installation depends on the application. While increasing the number of sound pathsincreases the accuracy of the measurement, signal attenuation increases as well. The optimum number ofsound paths for the parameters of the application will be determined automatically by the transmitter.As the transducers can be mounted with the transducer mounting fixture in reflect mode or diagonal mode,the number of sound paths can be adjusted optimally for the application..

a = transducer distance

Reflect mode, number of sound paths: 2

Diagonal mode, number of sound paths: 3

Direct mode, number of sound paths: 1 Direct mode, number of sound paths: 1,negative transducer distance

Typical Measurement Setup

Standard Volumetric Flow RateThe standard volumetric flow rate can be selected as physical quantity to be measured. It will be calculated in-ternally by:

N = . p/pN . TN/T . 1/K:where

The operational pressure p and the operational temperature T of the medium will be entered directly as fixedvalues into the transmitter.

or:If inputs are installed (optional), pressure and temperature can be measured by the customer and fed in thetransmitter.

The gas compressibility factor K will be entered in the transmitter:• as fixed value or• as approximation according to e.g. AGA8 or GERG

Example of a measurement setup in reflect mode with connection of the inputsto an external process pressure and process temperature measurement for standard volumetric flow rate calculation

N = standard volumetric flow rate= operating volumetric flow rate

pN = standard pressure (absolute value)p = operating pressure (absolute value)TN = standard temperature in KT = operating temperature in KK = gas compressibility factor

Transducer Selection

Step 1aSelect a Lamb wave transducer:

Step 1bIf the pipe wall thickness is not in the range of the Lamb wave transducers, select a shear wave transducer:

Step 2inner pipe diameter d dependent on the flow velocity v of the medium in the pipeThe transducers are selected from the characteristics (see next page). Lamb wave transducers are selectedfrom the left column, shear wave transducers from the right column.Lamb wave transducers: If the values d and v are not in the range, diagonal mode with 1 sound path may beused, i.e. the same characteristics can be used with doubling the inner pipe diameter. If the values are still notin the range, shear waves transducers regarding the pipe wall thickness have to be selected in step 1b.

Damping Mats (optional)Damping mats will be used for the gas measurement to reduce acoustic noise influences on the measure-ment.transducer damping matTransducer damping mats will be installed below the transducers.pipe damping matPipe damping mats will be installed if the sound propagation is disturbed at reflection points (e.g. flange,weld). Depending on the noise, the pipe damping mats will be installed at one or both sides of the transducerdamping mat. If the local conditions are unknown, pipe damping mats should be installed.
