Installation & Wiring 

1.

 

Select an installation site: 

Keep the following questions in mind when choosing a proper 
installation site: 

●

 

Is the chosen section of pipe always full of liquid? 

●

 

Are there at least 5 pipe diameters upstream and 3 pipe diameters 
downstream from any directional changes, pipe joints, or 
narrowing/widening of the pipe? 

 

Figure 2–1.  

Conditions at locations A, B, C, D, and E can interfere with the 
transmission of the ultrasonic wave and yield inaccurate or unreliable 
flow readings: 

●

 

A: Pipe may not be full 

●

 

B: Down flow 

●

 

C: Too close to elbow 

●

 

D: Air collects at the top of the horizontal pipe 

●

 

E: Sediment collects at the bottom of the horizontal pipe 

Note  

Selecting the proper installation location is essential to flow 

measurement reliability. Each application is unique and may require a 
variation of installation locations.
