Model: HFS-15,20,25
Application

Paddle type HFS series are designed to serve the best capacity with the firm structure, high reliability and high precision in the fluid inside the pipe. They are to be used for operation control. These series are structured in the way to open one circuit and to close the other circuit if the set flow is surpassed or not reached.

Their typical application is in interlock system to prevent equipment from starting up before sufficient flow feeding. For example, it is used to shut down equipment if the water flow drops to a predetermined value, it is also used for pump control in case the flow from a primary pump fails. Besides the liquid flow control applied widely in the flow or cooling/heating systems, the detection of air current in air routes is also adopting HFS switch in most cases.

They are used in the following pressure and temperature and can be used outdoors. They can be used in environment of high density of salt but not containing chlorine.
