Product Description

Description
Our company produces FS series piston flow switches, FSP series flow switches (target flow switches), FSF series float type flow switches and other flow switches, stainless steel, brass and plastic materials, a number of optional special forms, suitable for a wide range of industry flow monitoring applications, Including flameproof type and high temperature type, high pressure type and low price chemical resistant plastic type. FS series piston flow switches (also known as water flow relays) are composed of a housing and a switch assembly, its working principle is: a high-performance permanent magnet is installed inside the piston, and the piston moves through the fluid to drive the magnetic reed switch sealed inside the switch. There is only one moving part inside the switch, the working principle is simple, intuitive, reliable, its working state is stable, the components are wear free and the performance is stable, and only a small amount of maintenance work can have a long life. The working life can reach more than 100,000 times, which can be called cheap, fine and excellent quality. Corrosion resistant switch with a wide range of chemical compatibility. It is used to control the start and stop of the pump valve and protect the water shortage and cut-off of the cooling water circulation system. Ideal for water heating or purification, equipment cooling and general chemical treatment sites. The FS series flow switches are available in stainless steel or brass for robust construction and can be used in high pressure environments. Measure liquid flow in pipes (pipe diameter less than 2"). FSP series water flow switch (target flow switch) is often used as an independent safety control, excellent performance, reliable, can be installed in the water pipe and no corrosion to copper, the liquid has a small amount of particulate impurities in the environment, when the liquid flow reaches the set value, the switch signal is given, the main loop is closed or disconnected, typically used in the system chain, or cut-off protection places. Measure liquid flow in pipe (pipe diameter greater than 2")
