Spcification External Thread Diameter: G3/8" Interior diameter: 5.5mmExternal diameter: 9.5mmFlow range:0.3-10L/minFrequency: F=23.6 * Q (L / Min)Pressure range: Water pressure 0.8 MPa belowWorking voltage range: DC 5-18 VError: ± 3%Storage Temperature: -25℃～+80℃Storage Humidity: 25%～95%RHOutput Waveform: Square Wave,output pulse singalCable Length:15cm Material: Food grade POM Feature 1. The Water Flow Sensor is light, nimble outline, small size and easy to install. The bearings used in the rotating part.2. There is an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.3. Three wire connection: Red for positive, black for negative, yellow for pulse signal. Note 1. Installed in accordance with flow direction in the product, otherwise there is no signal output.2. A filter screen must be installed at the inlet of the sensor, in order to avoid particles and debris entering the sensor.   Wide application It is mainly used in water heater, coffee machine, water purifier, drinking fountain, beverage machine, campus smart card equipment, etc.
