WFS-1001-H Liquid water flow switchDetailed product description：

Application
The WFS water flow switch has Spdt output, excellent performance, high precision and reliability. It can be installed in water pipes and non corrosive liquids to copper. When the liquid flow rate reaches the set rate, it does not reach the set point, and one circuit is closed and the other circuit is opened. It is typically used in places with interlocking or flow protection.
The WFS series switch only uses liquid media above 0 ℃, and it can also be used in high salt or chlorine liquids, but it is not a flammable medium.
The WFS water flow switch can be installed outdoors, but attention should be paid to rain protection. It can be installed horizontally or vertically in the pipeline, and a uniform flow pipeline with 5 times the diameter of the pipeline on both sides should be maintained.
The WFS water flow switch is only used for operational control, and personnel and equipment losses may occur due to operational errors. It is necessary for installation personnel to increase safety limit control and alarm video systems to prevent control failures from occurring.

Note: The flow switch cannot be hit by water. If a quick closing valve is installed downstream of the flow switch, a throttle must be used.
