When thepoppet reaches the pre-set actuation setpoint, the switchcloses and remains closed until the flow is reduced. At flowsgreater than the setpoint, the switch stays closed until the flowis reduced below the setpoint. The differential between turnonand turn-off is 20% of the setpoint rate: i.e., turn-off for a 1.0GPM unit is approx. 0.8 GPM and occurs on decreasing flow.ORDER INFORMATION490.160.200MINIATURE FLOW SWITCH1.

Flow rate is estimated, or simplyconfirmed, by viewing the speed of theturning rotor. Either port may be used forincoming flow, and locking lens removeswith a quarter turn for quick cleanout.RFI Type RotorFlow sensors are easy tosee, easy to install and easy to afford.• RotorFlow operates as liquid passesthrough the body, the rotor spins at a rateproportional to flow. RotorFlow indicatorsmay be mounted with flow entering eitherport.FEATURES• This miniature float switch senses the presence or absence offluid flow in industrial and OEM applications.• The plastic body and fitting, titanium spring and Viton o-ringsproduce a low-cost flow-sensing device suitable for corrosiveor non-corrosive applications.• The connector fittings allow the universal body to be joined toeither pipe (1/8”, 1/4” or 1/2”) or hose (1/2” I.D.) and must beordered separately.• Unless otherwise specified, the units are calibrated for verticalmounting with the inlet port down and the lead-wires up.• Two body styles available. Angle body-Angle flow pattern, 0.1to 1.0 GPM preset (5) trip points; clean out cap; static areaabove spring; poppet moves away from flow path at high flow;can operate without spring if mounted vertically. Straight body-Straight flow pattern, 0.1 to 1.0 GPM preset (5) trip points; lowpressure drop at/or near threshold operate point; large pressuredrop at high flow; can operate w/o spring if mounted vertically.APPLICATIONS• Pumping systems protect pumps from loss of suction.• Plastic molding equipment sense a loss of cooling water.• Fire protection systems sense water leaks.SPECIFICATIONS• Operating pressure: 200 PSI @ 70°F• Operating temperature: 194°F (PVDF), 180°F (Polypro)• Set point accuracy: ±15%• Magnetic switch: 15W SPST resistive load.
