Air Flow Meters: A Computer's Best-Friend

Among the many applications that air flow meters are involved in monitoring and managing, there is one that strikes a particularly consonant chord of importance as I type this blog into being on my keyboard and computer. For many technologically advanced machines, a certain amount of air intake is key to keeping it from overheating; when a machine such as a computer is working at such speed and efficiency it is using a lot of energy, which causes the machine itself to get very warm. If it were not for... Read More

Flow Meter Suppliers: Knowing Your Products

Flow meter suppliers must know their products as well as the companies that manufacture them. Understanding how each flow meter model works and which one will best suit specific applications allows these suppliers to offer customers assistance as well as excellent products. Variations in flow meters consist of materials, size and a few differing techniques. Since there is such a wide variety of industries that require flow meter capabilities, such as the automotive, medical, chemical, food and beverage processing, utility services, petroleum and gas industries, flow meter suppliers who know...

Turbine Flow Meters: Within the Aerospace Industry

When watching a space shuttle launch from a pillow of red and orange and gray smoke, slowly rising to pierce through our atmosphere and into the vast solar system, turbine flow meters never cross my mind. However, they play a part in getting that space shuttle, as well as other aerospace crafts such as rockets into the great beyond. The engines that drive these large and powerful machines must be tested and tested well. Turbine flow meters play a part in the testing process to ensure the rocket and/or space... Read More

Sub-Metering of Natural Gas

Sub-Metering of Natural Gas Flexible Flow Measurement Delivers Improved Accuracy and Substantial Savings Unlike oil, natural gas exists in abundance in the United States. Of the natural gas consumed in the United States in 2011, 95% was produced domestically. The U.S. Energy Information Administration projects U.S. natural gas production to increase from 23.0 trillion cubic feet in 2011 to 33.1 trillion cubic feet in 2040, a 44% increase. Almost all of this increase in domestic natural gas production is due to projected growth in shale gas production, which will grow... Read More

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 plastic or metal parts that work together to produce a reading. The parts are manufactured to very close tolerances in order to provide readings with an accuracy as low as 2%. Air flow meters come in several types. Besides variations such as size or material, they may vary in pressure range, switching technology, and the presence and type of transmitters. These variations allow air flow meters to have applications in several industries. In the medical industry, flow meters are used to measure patients' air intake, allowing physicians to further determine the severity of any illness. These types of flow meters are called peak flow meters and are particularly beneficial for asthma patients. Air flow meters are also common in the automotive, petroleum and gas, utility services, HVAC, food processing and raw materials industries.

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