Re: REFLECTOR: Fuel gauges
I am looking at another approach to this idea. There has been many things
done with ultrasound. Anyone given this a thought? I have a contact that
has done many studies on ultrasound. Time to ask for his opinion.
Ultrasound should be able to penetrate glass and foam. I have heard that
they use ultrasound to check fluids in large containers.
