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.

Installation instructions

 

1,When magnetic materials or to flow switch a magnetic force materials near water flow switch, its characteristics may change.

 

2,In order to avoid particles, sundry into the flow switch, in the inlet must install screen pack.

 

3,In the use of the water flow switch before please read the parameters that if there are still questions please to our factory technical personnel consultation.

 

4,In the process of installation and use must cooperate relays (power in 3 W below), lest because of switch power small and dry reed pipe burn out.

 

5,The water flow switch installation use environment to avoid strong vibration and shaking place, in order to avoid water flow switch produce false action.
