A mass air flow sensor is one of the numerous tiny widgets and gewgaws that make up a modern automobile's electronic fuel injection system. In the MAF's case, it tells the car's computer how much ...

That's particularly true of the engine's Mass Air Flow (MAF) sensor. As part of the performance-boosting air intake system, the MAF monitors how much air is entering the engine, helping regulate ...

self-heated thermal flow sensors are simple, cheap, rugged, and sensitive. They rely on the relationship between airspeed (AF) and thermal impedance (ZT = o C/W) of a heated sensor as shown in the ...
