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. 

 

The principle of operation                                                                          

Flow switch is the presence or absence of flow through the output switch control signal to the water sensor switch,

the main switch signal. Divided into specific types normally open and normally closed type,

in the main water control work flow monitoring role to play.

Water flow switch and relay use with the usual components of the water control system, easy to use, no power is the flow switch on.

NOTE:

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.
