Vane type flow switch is the use of water flow force to drive the blade, to test whether the liquid flow in the pipe, when the liquid in the pipeline does not flow, the spring will press the magnet down the blade into a vertical, at this time the magnetic spring switch has NO action, the contact in the normally open (NO) position. When there is liquid flow in the pipeline and the liquid flow is enough to push the blade up about 20°~30°, the eccentric transmission piece above the blade will push the magnet up, and the magnet suction makes the magnetic spring switch action, then the contact is connected (close). Because of the different diameter of the blade length will also change.

Simple product structure, easy to judge the crux of the problem. Enclosure protection grade IP65, SPDT output. The service life of the switch can reach 1 million times. The simplicity of the safe and reliable product structure facilitates the efficient operation of the product. Explosion-proof type can also be used in dangerous places. Mechanical transmission structure, stable working efficiency. The blade length can be customized according to the actual working condition. The product can be used after installation and maintenance free.

Vane type flow switch is applicable to industries: shipbuilding, generator equipment, petrochemical, wastewater/water purification treatment, electronics, dyeing and finishing, chemical, chemical fiber and other industrial places.
