You now have the ability to customise the kit to suit your requirements with a range of single tank, double tank and triple tank gauges to be matched with 2.5 metre, 5 metre or 7.5 metre lead sender probes. 

With one push of the test button you are able to monitor the water levels of up to three tanks.

There is no need to wire in a 12 volt supply as the top indicator gauge comes complete with its own battery, which is easily replaced when the need arises.

The water gauge measures only H65mm x W65mm x D16mm so it is small enough to fit any application.

This easy to fit tank sender probe only requires one 22mm (7/8″) hole in the side of the tank and suits tanks from 100mm to 280mm (4″ to 11″) deep. 

The sender probe is sealed by a special grommet which is compressed in the hole when the nut is tightened and measures the water level by contact with the 5 sensors along the arm.

 It has no moving parts.
