Not accurate enough. I want to be able to quantify e.g how much water was used to water the garden. In a 25K litre tank, that's a very small change in level.

- groby_b 5y agoYou'll have the same issue with pressure sensors, though? Maybe a flow meter is a better choice for that. (Bonus, you can use that to cross-calibrate with the pressure/level sensor)
- snovv_crash 5y agoYep, if you use flow plus pressure, you can run an EKF to get much more accurate results.
