Air Flow Meters

Air flow meters are devices used to measure various aspects of the flow of air. Air flow meters may measure the volume of the air, the speed of the air or the mass of the air, depending on the type. Air flow meters are most frequently used to infer mass flow after taking various flow measurements such as absolute pressure, differential pressure, viscosity and temperature as air flows through a tube. Besides air, these flow meters can also measure many different types of gases including nitrogen, oxygen, argon, helium, hydrogen, natural gas and carbon dioxide.

Air flowmeters have many plasticor metal parts that work together to produce a reading. The parts aremanufactured to very close tolerances in order to provide readings with anaccuracy as low as 2%. Air flow meters come in several types. Besidesvariations such as size or material, they may vary in pressure range, switchingtechnology, and the presence and type of transmitters. These variations allowair flow meters to have applications in several industries. In the medicalindustry, flow meters are used to measure patients' air intake, allowingphysicians to further determine the severity of any illness. These types offlow meters are called peak flow meters and are particularly beneficial forasthma patients. Air flow meters are also common in the automotive, petroleumand gas, utility services, HVAC, food processing and raw materials industries.

There are four main categories of air flow meters that areidentified based on how they obtain a reading of the flow rate or quantity ofair. Differential pressure air flow metersare the most common type. These devices take both a primary and a secondarymeasurement and report the difference. The first measurement causes a change inkinetic energy by directing the air through a hole or orifice in the flow meterwhich is measured by the second element. Positive displacement meters separatethe air flow into specific volumes which are then counted. Vanes, gears,pistons, or diaphragms are commonly used to divide the air which is countedmechanically or electronically. Velocity air flow meters use a depthmeasurement and the average air velocity of the flow to produce a reading. Theyhave a greater range than differential pressure devices. The last category istrue mass air flow meters. They directly measure the mass of the fluid, not thevolume; two common kinds are thermal meters and Coriolis flow meters. Air flowmeters vary in how they obtain and report a reading but the list of parts mayinclude pressure ports, bellows, spindles, pinions, gear mechanisms, gauges,cell caps, magnets, sensors, pistons, nuts, seals, levers and more.
