Has anyone ever seen any specifications for the accuracy of external capacitive (foil) sensors ?
My current tank monitor uses the external capacitive setup and it seems less than accurate, possibly because there is only one trim resistor.
Measuring of my black water tank seems to be all over the place and I would LOVE to have something more accurate than the current 4 LED display.
In any case, I would like accuracy to be within maybe plus or minus 2-4% for the integration with OpenPlotter to make any sense.
Measuring at a particular level (inductive ?) seems pretty useless to me except maybe as a warning level (with a great big red flashing alarm light in the loo) before overflowing the black tank or similar.
