Flow meter for Crop sprayers

Hey everyone, I’ve heard lots of feedback in the spraying community of people needing a flow meter integrated into their system. They want to know exactly how much pesticide they are applying, as well as know when the tank is not spraying any more and can automatically RTL. Can anyone help or let me know of a way to do this/hack it together?

There are two liquid fuel type sensors supported, but both drivers are implemented as battery monitor back ends (to trigger the right failsafes).
See https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_BattMonitor
You could use either flow or level. Depending on use case, leaving as a battery backend might work well, to trigger rtl when low.

Great! I’ll have to get this tested to see how it works. Thanks james_pattison!
