Liquid Level in Halon Bottles

Colleagues -
Has anyone had success in applying UT techniques to detect the liquid level in vertically mounted halon cylinders? Available equipment is Epoch III flaw detector and standard contact probes. Thus far I have had no success due to uncertainty of acoustic properties of halon and lack of a perceptible change in bottle/halon interface using existing instrumentation. Before I embark on further research, I am posting this request.
Thanks in advance for any replies.

Velocity in liquid Halon is around ~800m/s
Calibrate your PE system for the far side of the container.
Alternatively try a through transmission technique.

Re: Liquid Level in Halon Bottles
Tim:
We have had success using infrared scanners and/or non-contact temperature probes along with hot water to measure halon levels in vertical cylinders located in oil facilities in Alaska. Hot water is poured down the outside of the cylinder, then the surface temperature is scanned with a non-contact IR sensor to discover the halon liquid level in the cylinder.

Thanks to all for the prompt & informed responses. I will try some of them next week and let the group know it turns out.
