China Nylon Material Paddle Type Flow Sensor

We are first class retailer, wholesaler, and exporter for Paddle Flow Sensor FS-M-PD018A in China since 2009. Quick response, fast delivery.
Introduction:
Paddle Flow Sensor FS-M-PD018A is a new structure of the mechanical flow switch, it follows a simple and reliable design philosophy, greatly improved the reliability of the flow switch, and much better than traditional one. This mechanical flow switch is free of bellows, and the electrical components are not directly contact with large temperature difference metals, so it won't appear this kind of phenomenon that electrical components produce condensate water lead to rust, it has a plurality of types for customers to choose to adapt different applications.
All-plastic flow switch is mainly designed for water / water loop heat pump air conditioning units and flow monitoring of heat-pump water heater. As the water heat pump unit suddenly disrupted of water flows during working time, caused any problems, like abnormal high pressure protection or lead to compressor failure.
Because of this kind of phenomenon may cause the heat exchanger freezing, causing unnecessary losses, so this flow switch is the best one to Water Heat Pumps.
Characteristics:
1. FS-M-PD018A with a Simple structure
2. Reliable
3. Long-time life
4. A new kind of common target flow switch
Installation:
Baffle flow switch is generally installed between Pump outlet and equipment outlet, and should not in Pump suction piping, because it is easy to make the pump with a bad absorption, flow switch cannot open. This flow switch must be horizontal. And the direction of flow must be consistent with the arrow which is on the copper shell, if not, the flow switch will be does not work. Also, large magnetic fields and vibration environments should be avoided.
