Description
Description:
Water flow sensor consists of a plastic valve bodya water rotorand a hall-effect sensor. When water flows through the rotorrotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
We have a comprehensive line of water flow sensors in different diameters. Check them out to find the one that meets your need most.
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.
