How to calculate custom tank "Sensor Level" percentage.

OBJECTIVE:

Set the custom parameters for an irregular shaped tank with a 600mm 30-240ohm KUS tank sender.

Cerbo GX.

QUESTION:

How does a user calculate with mathematical certainty the "Sensor Level" in % to calibrate a known volume in %?

EXAMPLE:

The photo attached show the set points that have been added for my particular installation to work correctly.

Take Note the sensor value at Point 1 is 52% and the volume is at 10% which corresponds to approximately 120mm of rise in the float at 100 Litres.

(I have calibrated all these values to work correctly by trial and error)

Since it is an irregular shape a linear answer is not possible as you know.

You would have to fill the tank with known quantities step by step. Take a reading at each step. And make that work on your scale.

So if your tank is 100litres and you want 10% increment steps. Fill with 10l take the reading. Add 10l take a reading. Repeat.

Unless you really want to math the math.
