Come on," I can tell when the tanks are half full or less in quarterly increments?" T.I.Terry - you should suss this one out.

3 lights?

Don't know Shirley, just along the Murray somewhere around Berri I think, have to be home for the 9th May. Just need to escape for a wee bit.

Well, ya can't blame me this time.... haven't been near your dunny for a while!!

But who knows, you may have been into a dunny that we may visit.

Hi, all.

T.I.Terry - should have said 4 lights actually displaying eighths, not as intended but a result of the fitting.

Shonky, we have had those type of gauges on the Coaster since it was converted, we had them on our yacht tanks years ago.
Good to know how much water that you have in your tanks.
I wasn't "there" was at the Dr getting a flu shot, the iPad was on charge home alone.

"tanks" here--more details please, what type of guage, how difficult to fit etc.

Hi, all.

Tanks - that'd be telling. The person who works it out receives a dozen best lamingtons emailed to him/her. Time for the thinking cap.

So do you have eight light indicators?

If you had said it measure from full to empty I'd have said 4 lights and 5 probes, all 4 lights on says the water level is between full and 3/4 full, 3 lights between 3/4 and half, 2 lights between 1/2 and 1/4, 1 light between 1/4 and empty. The probes are positioned 1 at the very bottom and 1 just off the bottom, 1 at 1/4, 1 at 1/2 and one at 3/4. The probe at the very bottom goes to battery negative, next one up empty, next 1/4, next 1/2, next 3/4, each of these wires going to the negative side of an LED. The other side of the LED has a suitable resistor and from there to bat positive. The water is a conductor, the probe that is in the water will connect through the water to the very bottom probe and back to bat negative, completing the circuit and powering the LED.

How'd I go Shonky, did you miss fitting the very bottom probe?

Hi, all.

T.I.Terry - nice try but no lamingtons. So the probe has 4 sensors 4.5cm apart, and measures about 18cm. It's inserted into the tank 15 cm up the side of the tank then swivelled until it touches the tank floor at a slight angle. This then allows the water in the tank to be measured in quarters, which is fine if your tank's 17cm high, not 35cm like ours. The result is the sensor indicates the tank is full until it's only 3/8ths full, or 5/8 empty. Depends whether you're Irish or not.

Ah, so you didn't order the correct sensor, nothing fitted wrong, just the wrong part fitted. I've never heard of that type of sensor array, doesn't sound like it's a one size fits all design like the individual probe type I was referring to that is the most common type used. The beauty of the individual probe design is a simple stainless machine screw through a piece of rubber hose does the job just fine, as long as you remember to put the screw head end in the tank, not the threaded end with the nuts on it, kind hard to stop the nut spinning as you tighten and no where to attach the wire once it's in
