Abstract

A process variable transmitter (10) for measuring a process variable of a process fluid in a vessel includes first and second pressure couplings (166,168) arranged to receive a first pressure P1 and a second pressure P2 of process fluid in the vessel. These pressures are related to the density of the process fluid. A sensor (204) provides a sensor output related to the process fluid in the vessel. Measurement circuitry (202) is configured to calculate a calculated process variable of the process fluid in the vessel based upon the first and second pressures P1, P2 and the sensed process variable.
