5 Selection of the Measuring Point

FLUXUS WD100, WD200

UMFLUXUS_F5WDV1-1EN, 2016-04-08

5.3

Selection of the Measurement Arrangement Taking into Account the Measuring
Range and the Measuring Conditions

disturbance source:pump

supply line: l

≥

50 D

Diagonal arrangement with 1 beam

Reflection arrangement with 1 beam

• wider flow velocity and sound speed range compared to

the reflection arrangement

• use in the presence of deposits on the inner pipe wall or

with strongly attenuating fluids (only 1 sound path)

• smaller flow velocity and sound speed range compared to

the diagonal arrangement

• transverse flow effects are compensated for because the

beam crosses the pipe in 2 directions

• higher accuracy of measurement because the accuracy

increases with the number of sound paths

Tab. 5.2: Recommended distance from disturbance sources; D – nominal pipe diameter at the measuring point, l – recommended distance
