That's the water level gauge for your water tank/tanks, showing half full.. Be surprised if it's 180 lt for one tank, usually about 90 lt each.

it looks like a large l shaped tank held up with marine ply. I measured it and hubby did the math

I suggest you include more meaningful headings on your posts if you want more members to read them. I usually skim past such posts ..... so many posts, so little time sort of thing.
Anyway there is a simple way to determine your tank capacity and understand how many litres each of those graduations on the gauge actually mean.
Start with the campervan/van level and run the water out. Don't do it by removing the bung because the pump may not fully empty it. You want to know your useable capacity so call it empty when the pump starts sucking air.
Get a bucket of known capacity (say 10 litres). Then run the hose slowly to fill it and time it. Adjust the flow rate so you know exactly how long it takes (say 2 minutes). That means 12 seconds per lite. Do it again to ensure accuracy.
Then transfer that running hose to start filling the tank. Inside, keep pressing the gauge button repeatedly until you see the next light come on. Note the time and do the same as each light comes on progressively. You can now calculate the tank capacity fairly accurately and what level it is when each of those lights goes out.

Depending on size of van, it is possible for larger tanks, Bob. I have a 20' Aluminium Tent and 2 X 190lt water tanks and 1 X 190lt grey water tank.
Keep Safe Bob.

Hi Douglas.
Just to let you know, I am a little envious, we only have common 85 litres water tanks.
2 off which will last about 4 days without being careful.

I know I'm in trouble when someone calls me Douglas.
You got me thinking there mate. I think 'Uncle Al' got up before me today as I have put a 1 in front of the 9. Therefore have lead you and others up the garden path. I have 2x90lt water tanks and 1x90lt grey water tank. I've had enough of bloody 'Uncle Al' lately. So, no need to be envious mate.
Take care both You and Mrs Radar.

That would be over 400 kg payload, including the tanks Doug, a lot for a 20 footer without anything else.
Mine are 90 lt, and I think that is standard size now, Jayco may be 80 lt.
We all get confused Al, make sure you have enough room for beers.
Stay safe Doug.

If this water tank is in a VW camper I doubt very much that it is 180 litres.
One thing with that type of gauge is that it only gives a rough indication - Essentially two lights on can mean anything from 'just on ½ full, to 'just under ¾ full. Assuming reading taken whilst on level ground.
We have a gauge which shows how many litres have been used. Useful povided you know how much 'useable' water a full tank holds & that you remember to reset it each time you fill up. (Yes I have forgotten the latter a few times!).
Rough drawing below not to scale, but shows how your gauge works.

Hoselink have flow metres.
They say minimum 20psi water pressure. I have no idea what caravans' water pressure is, but might be worth experimenting on the output side. If it doesn't work then use it on the input side filling up the tank.
This is the flow meter we have, I don't think any mimimum pressure is required & the readout itself can be mounted somewhere easy to see rather than on the hose itself which is handy when being used to measure usage. (rather than input). Topargee do one very similar aimed at the RV market (& charge considerably more - they also do a flush mounted one for a bit more again). The impeller fits just after the water pump & readout wherever you want. It's very accurate. Uses two AA batteries. I have replaced our batteries 2 or 3 times so far in over 5 years. Shows flow in real time (litres per minute) and total amount used. Reset to zero each time we fill the tank.
trying to figure out what this means , no idea what the reservoir is
We tried to measure the tank which looks like 180lt been away for 2.5 days notused a lot just drinking one 12lt shower small toilet flushing

I bought one of these to measure water input. It did the job for me. I think Bunnings may also carry them

The 4 lights indicates a reserve tank, which is no longer lit.
We filled till overflowing then tried again and it is still not lit.
We filled very slow like 2minitues for 8lt with the taps open, therefore we do not think there is any air in the tank
If you read the gauge as the first light is a reserve tank, which you don't have, that will probably never light up.
Then the next 4 lights are 1/4, 1/2, 3/4, full. The lights go out as the water level goes down.
So your 1st picture shows the tank is half full, there may be a slight delay with the lights as the water level goes down, it is only a guide.
It should light up from left to right as you fill it also.
Cheers Bob
Can only assume it is a faulty moniter
