The M-50X Explosion Proof Series low flow, flow switch monitors increasing and decreasing flow. It utilizes a single moving part that responds to fluid (liquid or gas) flowing within a system. This switch is suitable for a wide range of applications in industrial, biomedical, and OEM products. The flow monitor operates only when fluid is positively established.

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 thus producing the required signal. This signal can be used to actuate audible or visual alarms as well as relays, or other control. Piston travel is short which insures low hysteresis. Pressure drop across flow switch varies from 0.035 to 2 psi (at maximum flow rates for air and for liquid). Universal mounted units are outfitted with a spring that resets the piston.
