FS Flow Switch is made of metal shell and switch element. The principle of the product is to install a permanent magnet with reliable performance inside, and the flowing medium pushes the magnetic moving parts inside the switch, then the switch action is triggered by magnetism to achieve the alarm function. It is often used to control the start and stop of pump valves and the cut-off protection of cooling circulation system.
·Mechanical parts are completely isolated from electronic parts
·Minimal pressure loss
·Great repeatability
·Dual-use for vapor and liquid , can be used for water-cooling system and hydraulic system
