Abstract:
The present disclosure provides a method for measuring air mass flow using an air mass flow meter. The air mass flow meter comprises a sensor element for detecting an air mass flow (Q) and for generating a signal (S), and an electronic circuit for processing the signal (S) from the sensor element, wherein the sensor element generates a non-linear signal characteristic. The method may include converting the non-linear signal into a correcting, non-linear signal characteristic, then filtering the correcting, non-linear signal characteristic, then converting the filtered non-linear signal characteristic into a non-linear signal characteristic, and then generating an output signal relaying the signals (S) detected by the sensor element and processed by the linearization element, the filter element, and the conversion element.
