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:
“I date the end of the old republic and the birth of the empire to the invention, in the late thirties, of air conditioning. Before air conditioning, Washington was deserted from mid-June to September.... But after air conditioning and the Second World War arrived, more or less at the same time, Congress sits and sits while the presidents—or at least their staffs—never stop making mischief.”
—Gore Vidal (b. 1925)
“The joys of the evil flow away like a torrent.”
—Jean Racine (1639–1699)
“His meter was bitter, and ironic and spectacular and inviting: so was life. There wasn’t much other life during those times than to what his pen paid the tribute of poetic tragic glamour and offered the reconciliation of the familiarities of tragedy.”
—Zelda Fitzgerald (1900–1948)
