Principle、structure
WFS22 paddle flow switch is developed by ACOL engineer on the basis of analyzing and researching the disadvantages of other paddle flow switch in market. It with compact size、excellent performance. Compared with traditional target paddle flow switch, its performance is higher. Adopts plug-in mounting, mechanical type and micro switch.

Features
With very low pressure loss、good repeatability、dirt-resistant performance. The precise setting can be achieved by knob. Hermetic separation of electrical and hydraulic components. Not contain bellows, reed switch do not touch with metal parts, so the rust resulted from condensation water can be effectively avoided. Various models can meet different requirement. Imported micro switch can load heavy current, which can avoid the fault resulted from the reed switch. It is the best choice of central air conditioner and industrial flow control for flow protection.

Application
gaseous /liquid
It is mainly applicable to industrial automation/mechanical equipment/air compressing industry/refrigeration and air-conditioner/water-cool welding machine/cooling system of laser equipment/vacuum coating machine/electric stove/ silicon polycrystal ingot furnace. The magnet not contact with flowing water, so can normally work in sewage discharging system.
