2. 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 ...

3. Fluke Corporation - Wikipedia

   en.wikipedia.org/wiki/Fluke_Corporation

   Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .

4. Blower door - Wikipedia

   en.wikipedia.org/wiki/Blower_door

   The manual test consists of adjusting the fan to maintain a series of indoor/outdoor pressure differentials and recording the resulting average fan and indoor/outdoor pressures. Alternatively, a single-point test can be performed, where the blower door fan is ramped up to a reference indoor/outdoor pressure differential and the fan pressure is ...

5. Duct leakage testing - Wikipedia

   en.wikipedia.org/wiki/Duct_leakage_testing

   A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow. The combination of pressure and fan flow measurements are used to determine the ductwork airtightness.

6. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   Air flow control (CAV or VAV air handlers) Zone control (single zone or multi zone air handlers) Fan location (draw-through or blow-through) Direction of outlet air flow (front, up, or down) Package model (horizontal or vertical) But, the first method is very usual in HVAC market. In fact, most of the company advertise their products by air ...

7. Flow conditioning - Wikipedia

   en.wikipedia.org/wiki/Flow_conditioning

   The fundamental difference between the orifice meter and the turbine meter is the flow equation derivation. The orifice meter flow calculation is based on fluid flow fundamentals (a 1st Law of Thermodynamics derivation utilizing the pipe diameter and vena contracta diameters for the continuity equation). Deviations from theoretical expectation ...

8. Actual cubic feet per minute - Wikipedia

   en.wikipedia.org/wiki/Actual_cubic_feet_per_minute

   Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
