DESCRIPTION :
The main water flow sensor by copper body and plastic forming, water flow rotor components, steady flow components and hall
components. It's for 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 judgement,
adjust proportional valve control of electric current.
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.
PRINCIPLE :
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 co
mponets 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.
