Paddle Flow Switch

Paddle Flow Switch 1.Good Repeatability 2.Low Pressure Loss 3.Hermetic Separation of Electrical and Hydraulic Com.

With very low pressure loss,good repeatability,dirtresistant 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 req-uirement. Imported micro switch can load heavy current, which can avoid the fault resulted from the reed switch. It is the

best choiceof central air conditioner and industrial flow control. 

 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 in-got furnace. The magnet not contact with flowing water, so can normally work in sewage discharging system.
