Is this the sort of thing you are after?
TANK GAUGE FRESH WATER | Midland Chandlers
They are made by Henderson and cheaper direct.
I have one for water. Always on and very accurate

Thanks Guys - 3 posts with the same product kinda gives a recommendation. Just looking at them now and thinking i'll go for the thru tank one if I go this way - add it to the drain bung. I'm running hose from the tank so the 15mm Hep type fitting wont work for me (even though its cheaper!)
