G2" flow rate 60~1100L/min water Hall Turbine flow sensor meter Medium: water, or a liquid of similar concentration to water Material body : SUS304 ; plastic turbine . Reference Specification: Thread size : G2" Male thread, about OD5.9cm Flowrange:60~1100L/min +/-10% Flow Pulse: F(Hz)=(0.12xQ ) +/-5% ; Q=L/min (Horizontal installation test) Max.WorkingCurrent:15mA(DC5V) Min.WorkingVoltage:DC5V Working Voltage:DC 5V~ 18V LoadCapacity:=10mA(DC5V) OperatingWorkingTemperature: -25Degreecentigradeto+80Degreecentigrade Accuracy: +/-10% Cable connection: Red: positive + ; black : Negative - ; Yellow: Pulse NPNSignal. Flow Sensor series : Water Flow sensor includes a SUS /plastic body housing, plastic 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 ....
