flow sensor

RotorFlow Sensor is used to monitor the flow rate of the coolant.
Operation: The rotor reacts to turbulence, pulsation, entrained air, and other flow anomalies induced in the flow stream
by other process hardware. For optimum performance, install RotorFlow units where nominal flow conditions exist, with
ports located at the top. Incoming flow may be placed to either port. A minimum of 8° of straight pipe on the inlet side is
recommended. Frequency output (RFO) is determined by the velocity of the monitored fluid acting on the sensor rotor.
Input piping with an orifice smaller than that of the sensor input will effect the sensor output.
Installation: RotorFlow sensors connect to piping via NPT mating thread forms. The following guidelines are provided to

assist with installation for a leak-free seal, without damage to the unit:
1. Apply pipe thread sealant to male pipe threads.
2. Thread RotorFlow unit onto male pipe thread until hand-tight.

3. Tighten pipe 1 to 1-1/2 additional turns.
4. If improper seal results, continue turning pipe into unit in ¼ turn increments.
