Working performance Description:

Magnetic Flow Switch:

Flow switch is switch the on-off by the Magnet float when water comes in,

Water flow rate is up to the Min flow rate ,then in to the flow switch, the magnet float near to the wall where reed switch there. Then sensitivity and send out the signal to switch ON.

Hall Flow Sensor :

Water flow sensors includes copper body and plastic forming, water flow roto components,

Steady flow components and hall components. It uses in water dispenser, coffee machine and household applicances, which measuring the water flow , liquid flow rate.

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.
