A vortex sensor senses the generated vortices and provides a vortex signal. A filtering circuit is coupling to the vortex sensor to receive the vortex signal and provide an output indicative of fluid flow. A temperature sensor senses a temperature of the fluid and provides a temperature value, while a pressure sensor senses a pressure of the fluid and provides a pressure value. A processor is operably coupled to the filtering circuit, the temperature sensor, and the pressure sensor for receiving the output, the temperature value, and the pressure value, respectively. The processor calculates a calibration factor as a function of the output, the temperature value, and the pressure value for use in calculating the output value indicative of the flow rate of the fluid.
