An air flow meter is a device used to measure how much air is flowing through a tube. It is not the volume of the air passing through the tube that is measured. What is measured is the speed of air flowing through it in a defined time segment. Air flow meters are also known as air consumption meters. They are generally used for engines and other automotive purposes. Most modern, electronically controlled diesel engines rely on air flow meters ,as they are the only means of determining air intake. After measuring the amount of air passing into the engine, the computer can work out how much fuel to inject so as to get the perfect mixture for that specific throttle opening. The air flow meter also checks how much current is required to keep a wire at a specific temperature.
