Air Flow Meter

Air changes its density with temperature and pressure. An air flow meter is used in some automobiles to measure the quantity of air going into the internal combustion engine all modern electronically controlled diesel engines use an air flow meter citation needed as it is the only possible means of determining the air intake for them. A mass air flow sensor maf is a sensor used to determine the mass flow rate of air entering a fuel injected internal combustion engine.
