Flow Switches

ATEX_IECEX       

Malema™ flow switches are used to determine if the flow rate is above or below a certain flow rate. This value (the set point) can be fixed or adjustable. When the set point is reached, the response can be the actuation of an electric circuit. When the flow switch is actuated, it will stay in that condition until the flow rate moves back from the set point by some amount.

Malema offers the adjustable and fixed set point flow switches in piston and paddle style working principle. They are available in a variety of flow ranges, sizes and materials. The salient feature of buying a Malema™ flow switch is that it comes with a custom calibration option to precisely suit your application.  

The inline and by-pass style configurations, standard and custom fittings options offered make Malema™ flow switches a versatile flow measurement solution for various applications for gases and liquids. In addition, they are also available in explosion proof designs to install in hazardous locations.

Malema's customer support and application engineers are well trained and are ready to offer you the guidance when requested to select the right product to suit the application. 

M-50T/M-55T Series Fixed Set Point Flow Switches

Fixed setting PTFE flow switch with in-line flow. The M-50T Series low flow, flow switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system. These switches are suitable for a wide range of applications in industrial, biomedical, and OEM products. The flow monitors operate only when fluid is positively established.

M-61-F Series Fixed Set Point Flow Switches

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.
