  • Pipe must be full for accurate reading.
  • Minimum velocity is 1.5 ft./second. Recommended maximum velocity is 27 ft./second. The flow must be uniform at the point where the flow sensor is installed or an incorrect reading will result.
  • To accommodate a uniform flow, allow at least ten (10) pipe diameters upstream and five (5) pipe diameters downstream of the flow sensor. Non-uniform flow is often caused by elbows, partially open valves or an increase in pipe diameter.
