Product Description
Made of SUS304 material, with 1"NPT threads, this flow switch is applied to cooling water flow monitor of welding machine and purge flows of high-pressure washing machine. Ideal for critical low flow protection application such as pump seal cooling water
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.
The setting flow is in 100mL/min to 200 L/min ranges, it is made of stainless steel, plastic or brass material, the mounting thread can be selected G1/8", NPT1/2", BSPP1/2", BSPT1/2", NPT3/4", BSP3/4", NPT1",NPT2" Female or male thread.
