The piston type flow switch can be used for water flow detection and standby or abnormal flow alarm. Because of the high performance SS304 spring, the piston flow switch could work for oil,
The operating principle is based on a spring-propped magnetic piston which responds only to the motion of fluids within the line, not to static or system pressures. In the presence of fluid flow, controlled movement of the piston actuates an external hermetically sealed reed switch. This switch can be used to actuate audible or visual alarms, as well as relays, or other controls.
