ABSTRACT:
A flow meter for measuring flow rate and flow composition of a process fluid includes a microwave source configured to generate a microwave signal. A probe tip is coupled to the microwave source and in near field proximity to the process fluid. The probe tip is configured to apply the microwave signal to the process fluid. A microwave detector coupled to the probe tip is configured to detect a near field microwave signal from the process fluid in response to the applied microwave signal. Flow calculation circuitry determines flow rate and/or composition of the process fluid as a function of the detected microwave signal.
