Malema M-64 Fixed Set Point In Line Flow Switch

The Malema M-64 Fixed Set Point Flow Switches model, when triggered will be within 10% of the desired set point, all while offering repeatability of 2%. Available in 3/8”,1/2” and 3/4” sizes with stainless steel and PVC material options, the M-64 Flow Switches offer a water flow range of 400 to 26,000 CCM and air flow range of 28,500 to 1,980,000 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

Sample flow monitoring
Alarm actuation
Purge flows
Loss of flow protection
Semiconductor etch tools
Laser cooling equipment
