ABSTRACT:
A transmitter configured to measure a process variable of an industrial process, includes a pressure sensor configured to couple to a pressure of a fluid. An acoustic detector receives an acoustic signal from the fluid. Measurement circuitry coupled to the pressure sensor and the acoustic detector provides an output related to pressure of the fluid.
