A differential pressure (DP) multivariable meter will measure static pressure, differential pressure, and temperature. If you have a digital protocol like HART, then you can read this data using the primary variable (PV), secondary variable (SV), tertiary variable (TV), and quaternary variable (QV).
If you don’t have HART or some other digital protocol, then you can buy a device to split this data for more than one analog output. The market has several brands offering devices for signal conversion.
Basically, the converter will read the data in the PV, SV, TV, and QV and dedicate one output to each. The Triloop from Emerson can give you up to three outputs, and Pepperl+Fuchs has a similar device.
On one hand, this sort of solution comes up a lot for multivariable meters in analog systems. On the other, it still doesn’t offer you the best way to get your data. Digital communication gives you the best of the worlds, so if you have it, then try it. It might surprise you.
