Function: 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 Note: 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. Features: 1.
