Description

The TW Series flow switches are available with various lengths of the flexible stainless steel wire from 50mm to 300mm (2” to 12”). The required wire length must be specified when ordering.

The flow rate required to actuate the TW flow switch will depend on many variables such as turbulence, liquid viscosity and the exact surface area of sensor wire exposed to the flow.

Wire Trimming Calculator

As with our Paddle Flow Switches,  the Trailing Wires for our TW Series can be cut down in length to suit your pipework if needed. Please refer to our Paddle Trimming Calculator to find the correct wire length for your application. The width of the wires is 2mm.

Please note that if you do cut down the length of your trailing wire, you must either silver solder or tig weld the end of the wire to prevent fraying.
