Can a double-flange differential pressure transmitter be used as a densitometer?

Can a double-flange differential pressure transmitter be used as a densitometer? What is the measurement principle?
Does anyone have any practical experience in this area? Please share. Why is the atmosphere so dull?
Yes, it’s mainly a problem with the range setting
It can be used if high precision is not required. It's still P=9.8*density*height
It can still be used for liquids with basically stable density.
If the density remains relatively stable, it’s feasible; all that’s needed is to add simple calculations to the DCS system. If it’s not stable, then repeatedly adjusting the range of the measurements becomes a major hassle
The formula for the principle is P=9.8*density*height. So, the prerequisite is that you have another gauge to measure the liquid level; otherwise, with just one formula and two variables, how can you solve it?
I haven’t used it yet. Can it be made more widespread? Thank you
It can be used; for applications requiring high precision, one might consider Rosemount’s 3051SAM series of variable-range advanced measurement transmitters.
