G1/2" WATER FLOW HALL SENSOR SWITCH FLOW METER FLOWMETER COUNTER 1-30L/MIN
For the sense of the water flow rate on the following equipments: Thermostatic water heater, water purifier, water dispenser, smart card equipment, coffee machine etc.
Calculation Formula:f=(0.2*Q) Q=L/Min
1. When magnetic material is close with the sensor, its characteristics may vary.
2. In order to avoid particle debris, the sensor must be installed after a filter.
3. The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
Waterproof,Heat resistance,pressure resistance,cold resistance.
Easy to install.
