WH Type Transducer Mounting Methods
Two transducer-mounting methods are available. Select one of them in the menu according to specific application
conditions. They are: Z method, V method.
12.5.1
Z Mounting Method
Z method is the most commonly used mounting method for insertion-type ultrasonic Energy Meters, suitable for
pipe diameters ranging from 50 mm to 5000 mm. Due to strong signal strength and high measurement accuracy,
the Z method is preferable for pipe sections severely rusted or with too much scale formation on the inside wall.
When installing the transducer by using the Z method, be sure that the two transducers and the pipeline center axis
are in the same plane, but never in the 6 or 12 o
’
clock positions. See below:
12.5.2
V Mounting Method
V method is suitable for pipe diameters ranging from 300mm to 1200mm. It is used when only one side of the
pipe is available ( example: the other side is against a wall ) at the installation site, See below:
