2. Air flow bench - Wikipedia

   en.wikipedia.org/wiki/Air_flow_bench

   A flow bench consists of an air pump of some sort, a metering element, pressure and temperature measuring instruments such as manometers, and various controls. The test piece is attached in series with the pump and measuring element and air is pumped through the whole system.

3. Pitot tube - Wikipedia

   Air-flow is right to left. Types of pitot tubes A pitot-static tube connected to a manometer Pitot tube on Kamov Ka-26 helicopter A Formula One car during testing with frames holding many pitot tubes Location of pitot tubes on a Boeing 777. A pitot tube (/ ˈ p iː t oʊ / PEE-toh; also pitot probe) measures fluid flow velocity.

4. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   The most common choices for a manometer's fluid are mercury (Hg) and water; water is nontoxic and readily available, while mercury's density allows for a shorter column (and so a smaller manometer) to measure a given pressure. The abbreviation "W.C." or the words "water column" are often printed on gauges and measurements that use water for the ...

5. Blower door - Wikipedia

   en.wikipedia.org/wiki/Blower_door

   There are three primary components to a blower door: a calibrated, variable-speed blower or fan, capable of inducing a range of airflows sufficient to pressurize and depressurize a variety of building sizes; a pressure measurement instrument, called a manometer, to simultaneously measure the pressure differential induced across the face of the ...

6. Pressure head - Wikipedia

   en.wikipedia.org/wiki/Pressure_head

   The meter is "read" as a differential pressure head in centimeters or inches of water. The venturi meter and manometer is a common type of flow meter which can be used in many fluid applications to convert differential pressure heads into volumetric flow rate, linear fluid speed, or mass flow rate using Bernoulli's principle.

7. Air flow meter - Wikipedia

   en.wikipedia.org/wiki/Air_flow_meter

   An air flow meter is a device similar to an anemometer 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 mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...
