The principle of operation
Water flow sensor is the use of the Hall element to measure the Hall effect magnetic sensors
of physical quantities. Water flow sensor mainly consists of copper body, water the rotor assembly,
steady flow component and Hall sensors, installed in the water heater inlet side used to detect the
size and water flow off.
Applications
Mainly used for water heater, boiler, water dispensers, coffee machines, hot card machines,
steam equipment, water system, the campus card sales, selling self-help water systems,
water treatment equipment, cooling systems, mechanical equipment, instrumentation,
pharmaceutical equipment.
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.
