Abstract: A method for correcting an oscillator frequency of in particular a digital transmitter/receiver interface for transmitting measurement signals of a sensor to a control unit. The method includes outputting of a first reference frequency signal by the sensor, the first reference frequency signal and comparing it with a second reference frequency signal by the control unit, calculating a correction factor on the basis of the first and second reference frequency signals, and correcting the frequency signals representing actual measured quantities subsequently sent by the sensor and received by the control unit based on the calculated correction factor to obtain corrected frequency signals.

Abstract: Methods and/or devices for detecting the flow rate of a flowing medium, in particular the flow rate of a flowing air mass, are described, in which the flowing medium is detected with two evaluation methods that operate according to different principles and the two measurement signals obtained are set in relation to each other in order to determine correction methods. Since the two measurement methods react differently to interference effects, the comparison of the two output signals permits conclusions to be drawn as to the type and the order of magnitude of the interference effects and a corrected measurement signal can be obtained, which is independent of the interference effects.
