The principle of operation

     

      The main water flow sensor by copper body and plastic forming, water flow rotor components, steady flow components and hall components. It into water dispenser, coffee machine and household appliances the water used for measuring the water flow.

 

     When water flows through the rotor components, magnetic rotor rotating, and speed along with the flow of a linear change. Hall element output corresponding pulse signal feedback to the controller, the size of the flow of water by controller judgment, adjust proportional valve control of electric current.

 

     Water flow sensor fundamentally solve the differential water-gas valve flap type high pressure and start water valve easy misoperation appear dry and shortcomings.

It has reflected sensitive, long service life, action quick, safe and reliable, joins convenient traffic advantages such as the start low, deeply the general user affection.

 

     The main components of turbine rotor flow switch shell, magnetic rotor, brake ring composition. Use water flow switch mode, its performance than the mechanical differential pressure plate structure, and decrease the size. As the water through the turbine switch shell, promote magnetic rotor, different pole near the hall element hall element when conduction, and leave the hall componets disconnect. Thus, can measure the rotor speed. According to the measured data of the rotor speed and water flow, the output signal (voltage) curve, can be sure water dispenser, coffee machine and household appliances start water pressure, hydraulic pressure and startup corresponding start the flow of water and rotor The start of the speed.

 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.
