Fixed Set Point Flow Switches
Extreme accuracy is a highlight of Malema Fixed Set Point Flow Switch models. When triggered, these piston flow switches will be within 10% of the desired set point, all while offering repeatability of 5%. Malema Fixed Set Point Flow Switch models offer a custom set point calibration option that can be programed at our Malema facility before shipping. Standard pre-calibrated set point ranges on these inline flow switches are also available for immediate use and distribution. Options for SPST and SPDT flow switch configurations are available.

M-64 Series Fixed Set Point Flow Switches
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.
