Installation Site Selection

When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site:

Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe.
Ensure enough straight pipe length at least equal to the figure shown below for the upstream and down stream transducers installation.

Clamp-on Transducers Installation Methods

Clamp-on Ultrasonic Flow meters are installed simply by applying coupling compound on the bottom of the transducers and strapping them to the outside of the pipe.
