stainless steel electric water flow control switch

The water flow switch is installed on the water pipe through series connection or parallel connection,It is used hydraulic pressure (air pressure) to drive magnetic induction and convey switch signals.
The water flow switch send on or off signal according to the liquid flow volume, it is an important component of the fluid flow controls system.If the flow in the pipe is lager than start-up volume, the magnetic valve will be moved by the force of flow pressure, and then it will trigger the reed switch that same sealed in the vavle and send the signal . When the flow volume reduce lower than the start-up volume,magnetic valve core will be forced back to theoriginal place by the reset spring in the vavle.

  Jinhefeng industrial electrical co., ltd is devoting to designs and manufacture the sensing switch for more than 10 years .we have striven and now provides some of the best sensor solutions for liquid level, in addition to pressure and temperature measurement, for the most demanding float switch applications. Whether you need a single point float switch or continuous liquid level sensor, JHF Company can direct you to the proper float switch and liquid level sensor solution. Our Company offers standard float switch sensors in stock for same day shipment, and can also

Cautions
The pressure, temperature and electrical limitations shown for the specified level switches must not be exceeded.
The pressures and temperatures must take into consideration possible surges in the temperature and pressure of the system.
The liquids used must be compatible with materials of construction. Specifications of materials will be given upon request
Life expectancy of the switch varies with applications. Contact the factory if life cycle testing is required.
Ambient temperature changes can affect switch set points . Since specific gravities of liquids vary with temperature . Consult factory for assistance.
Level switches have been designed to be shock and vibration resistant. For maximum life .Both shock and vibration should be minimized. Consult factory for assistance .
Excessive contaminants in fluid may inhibit float operation .and occasional wipe down may be necessary
Level switches must not be field repaired.
Physical damage to product may render product unserviceable
Installation i vessel made from magnetic materials may affect operation.
