a twin set of microwave doppler radar thingies repurposed from pissoir
flushing activators ( you retreat and flushing advances ) arranged in a 45°
forward and 45° backward looking setup to remove attitude influences.
That was ~30 years ago.
The sensors where (afair) Panasonic microwave pissoir flushing activators.
Taken apart to get at the doppler signal and arranged pairwise
looking 45° forward and back down onto the road. ( $ forward - $backward
= true forward speed )
New to me. Since you know, you have a catalog or website about such radar
sensors, so I don't have to Google on this? Preferably with a digital fluid
level output?
today probably two of these would work ( IANAL or the TEC equiv ):

Could their microwave radiation detonate N2O vapor inside its pressurized
tank?
1mW ERP or thereabouts ?
But it is _Doppler_ as in SPEED detection ;-)
A Level sensor would not be a proper application for these.
Maybe if the level change is fast enough to give a useful doppler
signal? Long thin tank? could work ;-)
