Fuel Gauge Calibration

[Dockhead]

I'm planning to use my Cerbo, not yet installed, the same way. Only for black water and a second 475l water tank, not for fuel. I will not do this kind of calibration, because in my case both these tanks have straight sides and flat bottoms, but for fuel in an irregular tank I can see that it's worthwhile.

Note that Cerbo also takes inexpensive temperature sensors. I wish I had known that before I spent £££ on the Maretron temperature box years ago.

it looks like it shows 0-100% on the chart plotter. seems quite a good idea to me

It’s better than that, it shows 0-125 litres on the plotter, although percentage is also possible.

Eh? I think you’ve completely misunderstood the OP’s post.

The column with three decimals is sensor reading therefore it’ll be ohms. The variable resistance is calibrated to give a reading showing how full the tank is and it looks like it shows 0-100% on the chart plotter. seems quite a good idea to me.

Yes, I'm sure you're correct, but surely the fact that I stupidly took the three decimal points figure incorrectly, didn't warrant all the personal abuse from the op. But hey ho.

Posting a useful thread about calibrating sensors didn’t warrant pointless snarky posts from people uninterested in the topic.

We are where we are though. Perhaps next time just keep your thoughts to yourself rather than post unhelpful snark. Or post again, and we’ll be right back here with your hurt feelings.
