New all Stainless Steel Fuel and Water Sender fitted as original equipment by most major UK boat builders where corrosion resistance is important.

Made from 316 grade stainless steel they are reliable & easy to install.

A float, holding twin magnets, rises & falls with the water level and triggers a series of electronic switches housed & sealed within the tube.

The system is simple, with no mechanical moving parts to wear, so it is very durable and can withstand the constant movement of the contents much better than the 'car type' floating arm sender.

The sender head has a 1 1/4" BSP male thread, with double 'O' rings for an efficient seal and we offer a series of fitting flanges to suit most situations.

Our senders can be used to replace faulty floating arm units.

The sender is supplied to suit the depth of the tank and is calibrated during manufacture.

Fitting is as easy as screwing in the sender and joining two wires to the gauge.

We can supply senders to trigger any type of gauge, or have special calibration for heavily shaped tanks.

Senders come in a variety of sizes, if the size you want is not listed please contact us for a made to order quote.
