155421BSPP

155421BSPP is a RFO type RotorFlow sensor. The paddlewheel design combines high visibility rotors with solid-state electronics that are packaged into compact, panel mounting housings. This provides accurate flow rate output with integral visual confirmation, all with an unprecedented price/performance ratio. Typical applications are water purification/dispensing systems, chemical metering equipment, lasers and welders, water injection systems, semiconductor processing equipment, chillers and heat exchangers.
