what is the mass air flow sensor used for

Flow Sensor - an overview | ScienceDirect Topics

Mass flow sensors are widely-used to control the exact dosing of gases or liquids in many technical systems. The size of the sensor is adapted to the diameter of the pipe through which the fluid or gas is transported. Small diameter tubes make it necessary to use miniaturized sensors which are usually fabricated by exploiting silicon technology. A rather new application field for mass flow ...

What Does the Mass Airflow Sensor Do? | YourMechanic Advice

· How often does the mass airflow sensor need to be replaced? Mass airflow sensors (MAF) have no expiration date. They are not included on the manufacturer’s scheduled maintenance list of things to replace based on mileage, like spark plugs or filters. They can remain in service indefinitely as long as they continue to function correctly.

MASS AIR FLOW SENSOR (MAF) - Autoditex

A mass air flow (MAF) sensor responds to the amount of air flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the air. The sensor for volume consumption of air is used in many systems for management of engines for measuring value of the transitory cost of air.

Mass airflow sensor basics | MAF sensor working

Definition: The sensor used to determine mass flow rate of the air is known as mass airflow sensor. The air mass details are required in order to balance correct amount of fuel mass to the vehicle engine. As air density depends on temperature, altitude as well as application of forced induction, MAF sensors are more useful and more appropriate to determine quantity of air intake in each of the ...

What Does a Performance MAF Do? | AutoAnything Resource Center

· Your mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the ...

Mass Air Flow Sensor Performance -

The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine. The direct measurement of the air entering the engine is more accurate than calculating the airflow from the Manifold Absulte Pressure (MAP), the Intake Air Temperature (IAT), and the engine speed (speed/density). The MAF sensor has a battery feed, a ground, and a signal circuit. The MAF sensor used …
