Flow Sensor Location Guide
The preferred location for mounting
a ow sensor is on the top half of the
pipe. The best orientation is vertical. If
the sensor is mounted on the bottom of
the pipe, it may be susceptible to dirt
accumulation impacting operation.
When mounting a sensor after the pipe
diameter is reduced, length L must be at
least 2 times the pipe diameter.
When mounting a sensor after a valve,
length L must be at least 14 times the
pipe diameter.
When mounting a sensor after an elbow,
length L must be at least 6 times the
pipe diameter.
When mounting a sensor before a valve or
an elbow, length L must be at least equal
to the pipe diameter.
Before Valve or Elbow
L > 1 X PIPE DIA.
After Elbow
L > 6 X PIPE DIA.
After Valve
L > 14 X PIPE DIA.
After Reduction
L > 2 X PIPE DIA.
