2. Air flow meter - Wikipedia

   en.wikipedia.org/wiki/Air_flow_meter

   An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

3. Mass flow sensor - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_sensor

   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. Air changes its density with temperature and pressure.

5. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   Anemometer; Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.

6. Thermal mass flow meter - Wikipedia

   en.wikipedia.org/wiki/Thermal_mass_flow_meter

   Furthermore, a thermal mass flow meter can be built by measuring temperature differential across a silicon-based MEMS chip. Both types measure fluid mass flow rate by means of the heat convected from a heated surface to the flowing fluid. In the case of the thermal dispersion, or immersible, type of flow meter, the heat is transferred to the ...

7. Air flow bench - Wikipedia

   en.wikipedia.org/wiki/Air_flow_bench

   A flow bench is one of the primary tools of high performance engine builders, and porting cylinder heads would be strictly hit or miss without it. A flow bench consists of an air pump of some sort, a metering element, pressure and temperature measuring instruments such as manometers, and various controls. The test piece is attached in series ...
