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. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine.
Oct 8, 2020 · A flow sensor is a component that measures the flow of a fluid such as a gas or liquid. Flow sensors utilize both mechanical and electrical subsystems to measure changes in the fluid's physical attributes and calculate its flow.
The mass airflow sensor is a critical part of the internal combustion engine. Its primary role is to detect the air mass flow rate getting into the engine. The information helps the engine control unit to determine the fuel level supplied to the engine.
Usually the amount of a substance flowing (mass flow) is the most important, and if the fluid's density is constant, a volume flow measurement is a useful substitute that is generally easier to perform.
