We too have numerous Micromotion meters, and some of them we bought
specifically to get a density reading along with the flow. They work
well. You can get them with a variety of outputs; we typically use two
4-20mA, but they can be had with HART, FF, RS-485 Modbus, etc.
I think some other plants out here have some E+H ones measuring density
also.
As for Foxboro's claim to be able to measure 2-phase flow, that would be
useful in a few applications I know of, but I would have to have one in my
process for awhile to believe that. I'd be leery of doing the test,
however, as the last time I had a problem with a Foxboro meter, TAC was
not very helpful and the ultimate solution was to remove it and buy a
Rosemount. That meter was a vortex, and coriolis meters are even more
complex.

I am involved on a project in China and there is a control engineer over
there saying they can use a mass flow meter to measure density. I have
never heard of such a thing, has anyone out there in control world seen
such an application. If so could you point me to some literature on how
it is accomplished?
