Water Flow Switches:- 

General Indroduction :-

The paddle type WFS series flow controllers are specifically designed for use on liquid lines such as water, ethylene glycol or any other fluid which is not harmful to brass or phosphor bronze and which is not classified as a hazardous fluid.

When a WFS series flow controller is used as an operating control device and where an operating control device failure would result in personal injury and/or loss of property, it is the responsibility of the user to add safety devices that protect against control device failure.

The flow controller can be mounted in a horizontal or vertical pipeline but must be located in a section of pipe where there is a straight run of at least 5 pipe diameters on each side of the switch.
