Function

Measurement principleThe transducers are mounted on the pipe which is completely filled with the fluid. The ultrasonic signals are emitted alter-nately by a transducer and received by the other. The physical quantities are determined from the transit times of the ultra-sonic signals.

As the fluid where the ultrasound propagates is flowing, the transit time of the ultrasonic signal in flow direction is shorterthan the one against the flow direction.

The transit time difference ∆t is measured and allows the flowmeter to determine the average flow velocity along the prop-agation path of the ultrasonic signals. A flow profile correction is then performed in order to obtain the area averaged flowvelocity, which is proportional to the volumetric flow rate.

The integrated microprocessors control the entire measuring cycle. The received ultrasonic signals are checked for mea-surement usability and evaluated for their reliability. Noise signals are eliminated.

Number of sound pathsThe number of sound paths is the number of transits of the ultrasonic signal through the fluid in the pipe. Depending on thenumber of sound paths, the following methods of installation exist:

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

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

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

The preferred method of installation depends on the application. While increasing the number of sound paths increasesthe accuracy of the measurement, signal attenuation increases as well. The optimum number of sound paths for the pa-rameters of the application will be determined automatically by the transmitter.

As the transducers can be mounted with the transducer mounting fixture in reflect arrangement or diagonal arrangement,the number of sound paths can be adjusted optimally for the application.

a - transducer distance

Typical measurement setup

Reflect arrangement, number of sound paths: 2

Diagonal arrangement, number of sound paths: 3

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

• as approximation according to e.g., AGA8 or GERG

Transducer selection

Step 1a

Select a Lamb wave transducer:

Step 1b

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

Step 2

inner pipe diameter d dependent on the flow velocity v of the fluid in the pipe

The transducers are selected from the characteristics (see next page). Lamb wave transducers are selected from the leftcolumn, shear wave transducers from the right column.

Lamb wave transducers: If the values d and v are not in the range, the diagonal arrangement 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 not in therange, shear waves transducers regarding the pipe wall thickness have to be selected in step 1b.

Wall thickness measurement (optional)The pipe wall thickness is an important pipe parameter which has to be determined exactly for a good measurement. How-ever, the pipe wall thickness often is unknown.

The wall thickness probe can be connected to the transmitter instead of the flow transducers and the wall thickness mea-surement mode is activated automatically.

Acoustic coupling compound is applied to the wall thickness probe which then is placed firmly on the pipe. The wall thick-ness is displayed and can be stored directly in the transmitter.
