Function

Measuring Principle

For the flow measurement 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 one side of a pipe, reflected onthe opposite side and received by a second transducer. These signals are emitted alternatively in flow direc-tion and against it.

As the medium in which the signals propagate is flowing, the transit time of the ultrasonic signals in flow di-rection is shorter than against the flow direction.

The transit time difference t is measured and allows to determine the average flow velocity on the propaga-tion path of the ultrasonic signals. A flow profile correction is then performed in order to obtain the area aver-age of the flow velocity, which is proportional to the volume flow.

The received ultrasonic signals will be checked for their usefulness for the measurement and the plausibilityof the measured values will be evaluated. The complete measuring cycle is controlled by the integrated mi-croprocessors. Disturbance signals will be eliminated by statistical signal processing.

Path of the ultrasonic signal Transit time difference t

Calculation of the Volume Flow

Q = kRe . A . k . t/(2 . tt)

with:

Q - volume flowkRe- fluid mechanics correction factorA - cross-sectional area of the pipek - flowmeter constantt - transit time differencett - transit time the medium

.

Number of Sound Paths

The number of sound paths is the number of transits of the ultrasonic signals through the medium in the pipe.

reflection mode: number of sound paths = even, the transducers are mounted on the same side of the pipe,correct positioning of the transducers easier

diagonal mode: number of sound paths = odd, the transducers are mounted on opposite sides of the pipe

The mode to be used depends on the application. If the number of sound paths is increased, the accuracy ofthe measurement will be better, but the signal attenuation is increased.

In case of a high signal attenuation by medium, pipe and coatings, diagonal mode with 1 sound path will beused.

The optimum number of sound paths for the parameters of the application will be detemined automatically bythe flowmeter

As the transducers can be mounted with the transducer mounting fixture (option) in reflection mode or diago-nal mode the number of sound paths can be adjusted optimally to the application.

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

Reflex mode, number of sound paths: 2

Typical Measurement Setup

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

Standard Volume Flow

The standard volume flow can be selected as physical quantity to be measured. It will be calculated internallyby:

VN = V . p/pN . TN/T . 1/K

with:

VN - standard volume flow V - operational volume flow pN - standard pressure (absolute value) p - operational pressure (absolute value) TN - standard temperature in K T - operational temperature in K K - gas compressibility factor

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

Or:

If inputs are installed (option), pressure and temperature can be measured by the customer and fed in theflowmeter.

The gas compressibility factor K will be entered in the flowmeter:

• as fixed value or

• 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 medium in the pipe

The 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.
