Simple Working Principle Flow Switch for Solar Heater

MR-B668-2 drinking water heater flow switchOperating principle As liquid passes through the flow sensor body, the magnetic rotor spins at a rate proportional to flow. This Causes a series of magnetic fields (the rotor vanes) to excite the Hall Effect sensor, producing a series of voltage pulsesSpecificationsElectronic water flow sensor  FLW010011.Low cost 2.Long life 3.Simple installation 4.Wide applicationsIntroductionFlow switch consists of magnetic core, rotating impeller, external casing and reed switch. Flow through the sensor activates the magnetic core to trigger switch action, with signal output.withstand hydraulic pressure≤0.35Mpa voltage ratingDC5V-24V  insulation resistance>100MΩ  precision10-132L/H flow pulseF=(18Q)+5% Q=L/minoutput pulse duty cycle50%±10%  max output pulse voltage>DC4.7V  min output pulse voltage
