GEMS Sensors popularized the RotorFlow’s 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…all with an unprecedented price/performance ratio. Typical applications include Water Purification/Dispensing Systems, Chemical Metering Equipment, Lasers and Welders, Water Injection Systems, Semiconductor Processing Equipment, Chillers and Heat Exchangers.
