ABSTRACT:
A mass flow rate sensor for providing an output signal related to mass flow rate past the sensor includes a bridge circuit for generating a first mass flow rate-related signal containing temperature-related errors and mass flow rate-related errors, a resistance for generating a second signal providing temperature error correction, and a resistance for generating a third signal providing mass flow rate error correction. Electrical circuitry operatively couples the bridge circuit and resistances together to provide the output signal. A method for providing an output signal related to mass flow rate includes the steps of generating a first mass flow rate-related signal containing temperature-related errors and mass flow rate-related errors, generating a second signal providing temperature error correction, generating a third signal providing mass flow rate error correction, and combining the first, second and third signals together to provide the output signal.
