Overview

The FM series flow switch is built tough for the most arduous industrial and mining applications.

It is a rugged but highly sensitive paddle flow switch suitable for a wide range of flow sensing applications. The FM series flow switch can be supplied with a glass fibre reinforced Polypropylene paddle or a Stainless Steel paddle.

A unique feature of the FM flow switch is its built in manual override. The manual override allows the flow switch to be switched on at any time at the press of a button regardless of lack of flow.

A magnetic coupling system is built into each FM flow switch and couples the paddles movement to the high compliance switch through a solid wall of stainless steel and aluminum. The result is a high-pressure flow switch with no seals diaphragms or bellows or other points of potential failure. The switch is suitable for use in bore water, sea water and in many chemical solutions.

There is also a dedicated Diesel and high temperature compatible version available with a stainless steel paddle.
