Non-Adjustable Flow Switches

Operation
The operating principle is based on a free floating 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.
