Most boats suffer badly from unreliable tank level gauges, this is a particular problem with dirty water tanks. The main problem is the corrosive nature of the salt water and that float meters are damaged in the tanks. The measuring device must not be effected by the movement or the corrosive nature of the fluid it is measuring. The best way to achieve this is the way ships and other quality tank meters work by using pneumatics. This has always proved too expensive to miniaturize for leisure craft, use until now.

This works on the principle that the back pressure on a liquid is directly proportional to its depth and the depth can be calculated using a complex software programme.

For a more accurate analysis the L.E.D display can be connected to the optional L.C.D display which will scan up to 8 tanks and display the depth in % full in rotation, when the fill button is pushed on the tank, for example tank 6, then the L.C.D. display will lock onto that channel.

Fully programmable. The user programmes in 1) tank depth 2) fluid density (water, diesel, dirty water, petrol) 3) operation mode. When these three pieces of information are set simply connect the unit to a pipe which is about 10 mm off the bottom of the tank and the L.E.D. display will give a good indication of the depth.

The system must only be used where the pump sensor unit can be fitted above the level of the highest point on the tank system, i.e. above the height of the deck filler system or a U bend in the tube going above the filler, i.e. in an over fill condition liquid must not run into the unit.
