Product Description

Stainless Steel Piston Flow Switch
Description
FS series flow switches is low cost switches with proven accuracy, ideal for critical low flow or high flow protection applications such as pump seal cooling water, pump inlet flow protection, cooling circuit protection, High and low flow rate alarm, valve failure, pump starting or failure, pipe blockage or rupture.  Using these in-line flow switches to monitor min/max values of liquid flow in order to switches a valve or to establish an on or off control loop, electrical circuit is isolated from the fluid path.

The operating principle is based on a free-floating magnetic piston, which responds only to the motion of fluid within the pipe line. Not to static or system pressure, in the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch, thus producing the required signal this signal can be used to actuate audible or visual alarms as well as relays or other

A piston operated flow switch is a device which utilizes the force exerted on a piston of flow switch in a flowing fluid to actuate an electric switch at a predetermined rate of flow. The electric switch may be used to start or stop pumps, open or close valves, actuate a warning lamp, sound on alarm, etc.
