Description:
GEMS Sensors popularized the rotor paddlewheel design by combining high visibility rotors with solid-state electronics that are packaged into compact, panel mounting housings. They provide accurate flow rate output with integral visual confirmation. The sensor is a GEMS RFO Type. It features a VDC pulsed output. The standard accuracy range of the sensor is 4 to 20 GPM,(15.14 to 75.70 LPM). With the installation of the included low flow adapter, the accuracy range of the sensor is 1.5 to 12 GPM, (5.67 to 45.42 LPM).
These flow sensors monitor dynamic fluid flow. 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 the 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.
