Air flow meter
From Wikipedia, the free encyclopedia
An air flow meter, also know as air consumption meter, is a device that measures how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the amount of mass flowing through the device in a defined time segment. So, an air flow meter is just an application of mass flow meters for a special medium.
The typical physical value is kg/h.

[edit] Air flow meter in cars
An air flow meter is used in some cars to measure the quantity of air going to the engine. The electronic control unit then calculates how much fuel is needed to inject into the intake manifold.
[edit] Air flow meter for R&D of cars
In the development process of combustion engines with engine test stands an air flow meter/air flow measuring unit is used for measuring the continuous gravimetric air consumption of combustion engines.
