What is a normal mass air flow reading?

What is a normal mass air flow reading?

With the engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds.

How is an airflow meter used in a duct?

Calibrated for compressed air. With a probe on a cord, these meters access hard-to-reach places in duct. This meter is often used to test airflow through supply and return grilles and air filters.

How is the PCE-VA 11 air flow meter used?

The Air Flow Meter PCE-VA 11 is an extensively used measuring instrument. This air flow meter offers the opportunity to determine air speeds, air temperature and infrared temperature. The illuminated LCD allows comfortable readings and facilitates use in dimly lit areas.

How does an air flow meter work in a car?

In automobiles. The vane (flap) type air flow meters (Bosch L- Jetronic and early Motronic EFI systems or Hitachi) actually measure air volume, whereas the later “hot wire” and “hot film” air mass meters measure the mass of air flow. The flap-type meter includes a spring which returns the internal flap to the initial position.

How does a flap type air flow meter work?

The flap-type meter includes a spring which returns the internal flap to the initial position. Sometimes if the spring is tensioned too tightly, it can restrict the incoming air and it would cause the intake air speed to increase when not opened fully.
