6.2.1 Preparation
6.2.1.1 Measuring point selection
The correct selection of the measuring point is crucial for achieving reliable measure -
ment results and a high measurement accuracy.
A measurement on a pipe is possible if:
• the ultrasound propagates with a sufficiently high amplitude
• the flow profile is fully developed
The correct selection of the measuring point and the correct transducer positioning guar
-
antee that the sound signal will be received under optimum conditions and evaluated cor -
rectly.
Because of the variety of applications and the different factors that influence the mea
-
surement, there is no standard solution for the transducer positioning.
The measurement is influenced by the following factors:
– diameter, material, lining, wall thickness and shape of the pipe
– fluid
– gas bubbles in the fluid
