What is an Air Flow Meter?

According to Wikipedia (which offers a great geeky definition) – “an air flow meter, is a device that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the actual speed of the air flowing through the device in a defined time segment.
