Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia

Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… … Wikipedia
Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate 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… … Wikipedia
Compressible flow — is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number (the ratio of the flow… … Wikipedia
