Mass Air Flow (MAF) Sensor
The miromechanical Mass Air Flow (MAF) sensor is a hot film thermal flowmeter with an integrated temperature sensor which detects the intake air temperature. The sensor is designed for recording load on combustion engines with diesel fuel injection and has a cylinder size in accordance with the required air flow rate. The MAF Sensor is mounted inline in the air intake between the air filter and the turbocharger. See Fig 1.
