5.2.5 Requirements on Transducer Installation Angle
When being installed on horizontal pipes, the transducer should be installed at 3
o’clock or 9 o’clock, i.e. on both sides of the pipe. It’ not recommended to install it on
top or at bottom of the pipe because it’s easy to cause bubbles at the top and
accumulate sands or impurities at the bottom.

The measurement point should be in the pipe section with relatively new inner wall
with no or relatively less scaling. The pipe must be made of compact material. When
selecting the installation point, DO ensure no welding seams or other gaps.
