Paddle Trimming Calculator

The Paddles and Trailing Wires for our switches come in set lengths. These Paddles and Trailing Wires can be cut down to suit your pipework and flow rate. We recommend using our Paddle Trimming Calculator to find the correct paddle length for your application.

Chemical Compatibility Guides

The majority of our products have no wetted metal parts, meaning that can be used reliably in aggressive liquids such as acids and alkalis, sea water and saline ground water. Please see our Chemical Compatibility guides for more information about the suitability of our switches in your application.
