G2" flow rate 10~200L/min water Hall Turbine flow sensor meter Material body : SUS304 ; Black plastic turbine support. Reference Specification: Threadsize:Male g2 - OD59MM Length size : L75mm Flowrange:10~200L/min +/-5% FlowPulse: F(Hz)=(0.2xQ ) +-3% Q=L/min 1L water = about 12 Pulse Max.WorkingCurrent:15mA(DC5V) Min.WorkingVoltage:DC3.5V Working Voltage:DC 5V~ 24V LoadCapacity:=10mA(DC5V) OperatingWorkingTemperature: -25Degreecentigradeto+80Degreecentigrade Accuracy: 3~5% Cable connection: Red: positive + ; black : Negative - ; Yellow: Pulse NPNSignal. Flow Sensor series : Water Flow sensor includes a plastic/ SUS body housing, a water rotor, and a hall-effect sensor, PCB electronics board. Working performance : When the water flows through the rotor, then rotor is rolled. the hall-effect sensor outputs the corresponding pulse signal . The flow sensor is suitable to detect the flow in water dispenser or coffee machine ....
