                      Product Overview

                      155421 is a RotorFlow® RFO-type flow rate monitoring sensor. It is popularized the RotorFlow's paddlewheel design by combining high visibility rotors with solid-state electronics that are packaged into compact, panel mounting housings. It provides accurate flow rate output with integral visual confirmation. RFO type features a VDC pulsed output. Typical application includes water purification/dispensing system, chemical metering equipment, laser and welders, water injection system, semiconductor processing equipment, chillers and heat exchangers.

                      • Accurate flow rate indication with integral visual confirmation
                      • Polypropylene body material
                      • Port size NPT is .25", flow range from 0.1 to 1GPM low range (accuracy)/0.5 to 5GPM (standard)
                      • 200 SSU max viscosity, 4.5 to 24VDC input power range
                      • 8mA current consumption (no load), 70mA max current source output
                      • Frequency output range from 15Hz to 225Hz
                      • 24" long, 22 AWG, (3) conductor PVC cable electrical termination
                      • Operating temperature range from -29 to 82°C
