Abstract: A sensor system (100) for sensing a process variable of fluid at a first location including a variable resonator (200, 220) disposed at the first location (106) having a resonant frequency (110) which varies in response to the process variable of the fluid and responsively provides a resonant acoustic signal at the resonant frequency indicative of the process variable. An acoustic sensor (118) disposed at a second location which is spaced apart from the variable resonator is configured to receive the resonant acoustic signal transmitted from the variable resonator (110). Measurement circuitry (102) coupled to the acoustic sensor (118) configured to provide a process variable output related to the process variable of the fluid in response to the received resonant acoustic signal.
