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 ...
Airflow, or air flow, ... In engineering, airflow is a measurement of the amount of air per unit of time that flows through a particular device. It can be described ...
A new parameter, effective Air Changes per Hour (called ACHH by Mojtaba Zabihi et. al. [8]), which incorporates both the flow rate and large-scale airflow patterns, could provide a more accurate measure of how efficiently air is supplied and circulated within a room. This is particularly important for effectively managing airborne disease spread.
Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters ...
Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified design airflow or water flow. When beginning the balance of a system, you must locate the terminal with the least amount of flow in regards to the engineer's drawing.
Single fan blower door system. A blower door is a machine used to perform a building air leakage test. It can also be used to measure airflow between building zones, to test ductwork airtightness and to help physically locate air leakage sites in the building envelope.
A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. 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.
Airwatt or air watt is a unit of measurement that represents the true suction power of vacuum cleaners. It is calculated by multiplying the airflow (in cubic metres per second ) by the suction pressure (in pascals ).
