The Malema M-60 Fixed Set Point Flow Switch with inline flow monitors increasing and decreasing flow. The flow switch will be within 10% of the desired set point with a repeatability of 2% when triggered. It utilizes a single moving part which responds to fluid (liquid or gas) flowing within a system.

The flow switch is suitable for a wide range of applications used in semiconductor, industrial, biomedical, and OEM products with single-pole, dual-throw (SPDT) configuration and models available in acrylic and stainless steel. The M-60 is available standard with 1/4" FNPT connections. The M-60 Flow Switch has a water flow range of 10 to 1,600 CCM and air flow range of 300 to 55,000 SCCM.

The operating principle is based on a 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. Applications include sample flow monitoring, alarm actuation, purge flows, loss of flow protection, semiconductor etch tools, and laser cooling equipment.
