Air-flow meter for measuring mass flow rate of fluid in air intake manifold of e.g. diesel engine, has transfer element transferring signals processed by linearization element, filter element and conversion element

摘要

The air-flow meter (6) has a sensor element (1) producing a non-linear signal characteristic curve. An electronic circuit (7) comprises a linearization element (2) for converting the non-linear signal characteristic curve from the sensor element into a linear signal characteristic curve. A conversion element (4) converts the linear signal characteristic curve into the non-linear signal characteristic curve. A transfer element (5) transfers signals processed by the linearization element, a filter element (3) and the conversion element. An independent claim is also included for a method for processing signals of an air-flow meter.
