Guided Wave Radar Interface

[roydm]

Hi everyone, I have a couple of questions on GWR.
Has anyone used Guided Wave Radar to measure interface where the Upper level is acidic water and the lower level Hydrocarbon. My intuition tells me the radar will not be able to penetrate the highly conductive water layer, am I correct?
Where you have an emulsion at the interface would you get a good echo?
We normally use bubhle tubes for this application but a new customer is asking for radar.
Personaly I think displacer type transmitters would work better, any thoughts on that type?

Thanks & Regards

Yes, air would be bad, we use Nitrogen.
Both bubble tubes are below the surface, each has it's own purge supply, both HP & LP see the vessel pressure.
We can measure interface or density.

OK Cheers.

Is it a packed vessel or do you compensate for overall level?
