Description

The TWM trailing wire flow switch is supplied with a 316 stainless steel process connection and is available in 3/4” or 1” with BSP or NPT threads. The switch housing is machined from solid billet Aluminium. A 500V Single Pole Double Throw (S.P.D.T) microswitch for general control circuit applications is supplied as standard with the TWM.

In addition a low voltage low wetting current model is available for signalling applications. A unique feature of the TWM flow switch is its built in manual override. Using the manual override allows the system to be manually started at any time by simply pressing the button. It also makes testing and commissioning of systems very simple.

The TWM flow switch is available with wire sensors in various lengths from 50mm to 300mm (2” to 12”). The required wire length must be specified when ordering. The flow rate required to actuate the TWM will depend on many variables such as turbulence, liquid viscosity and the surface area of sensor wire exposed to the flow.
