Rotor Flow Indicator & Transmitter -- C156261-Image

CFR0 flow transmitters combine visual confirmation of flow with a pulse or conditioned 0-10 V output proportional to flow rate. As liquid passes through the meter body, a magnetic rotor spins at a rate proportional to flow. This causes a series of magnetic fields (the rotor vanes) to excite a hall effect sensor, producing a series of voltage pulses. The output pulses (CRFO) are at the same voltage level as the input (4.5 - 24 VDC) with a frequency proportional to the flow rate. The output signal can be utilized by digital rate meters, totalizers, or other electronic controllers. CRFA Type analog sensors condition the output signal to 0-10 VDC.

Typical applications include water purification/dispensing systems, chemical metering equipment, lasers and welders, water injection systems, semiconductor processing equipment, chillers and heat exchangers.
