An air flow meter, is a device 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 actual speed of the air flowing through the device in a defined time segment. Thus air flow meters are simply an application of mass flow meters for a special medium. Typically, mass air flow measurements are expressed in the units of kilograms per second (kg/s).
Famous quotes containing the words air, flow and/or meter:
“Mothers of America
let your kids go to the movies!
get them out of the house so they won’t know what you’re up to
it’s true that fresh air is good for the body
but what about the soul
that grows in darkness, embossed by silvery images”
—Frank O’Hara (1926–1966)
“There St. John mingles with my friendly bowl
The feast of reason and the flow of soul;”
—Alexander Pope (1688–1744)
“Much poetry seems to be aware of its situation in time and of its relation to the metronome, the clock, and the calendar. ... The season or month is there to be felt; the day is there to be seized. Poems beginning “When” are much more numerous than those beginning “Where” of “If.” As the meter is running, the recurrent message tapped out by the passing of measured time is mortality.”
—William Harmon (b. 1938)
