Air Flow Meter Hvac Duct

Air velocity meters commonly called anemometers are used to measure the speed and or volume of air movement.

Air flow meter hvac duct.

A multi point self averaging pitot traverse station. Mechanical ductwork is the most common means for distributing the conditioned air throughout most commercial buildings. Low and medium pressure. Duct flow meters for air gas rheotherm flow sensing probes for duct gases are easy to install and provide long term service with little or no maintenance.

Measuring air flow with anemometers has been limited in the past by time. A combination air equalizer straightener with self averaging pitot tube traverse station. Since the air pressure in a duct directly affects the flow of air measuring the air pressure is important. Air pressure in a tire is measured in psi pounds per square inch.

The duct system provides the best opportunities for accurate airflow measurement due to its controlled dimensions and the typical obstructions found within a duct system are generally well defined. The amp series ampliflow air velocity sensor is designed to measure air flow velocity in hvac duct systems. Both psi and inches wg measure the same thing the amount of pressure on a given amount of area. Amazon s choice for hvac duct flow meter btmeter bt 100 handheld anemometer digital wind speed meter gauge for hvac cfm tester air flow velocity wind chill 14 113 wind temperature 4 5 out of 5 stars 571.

Doubling the duct diameter reduces the friction loss by factor 32. Lo flo ss pitot traverse station. However anemometers are also critical instruments for applications such as balancing forced hot air hvac systems the analysis of ventilation systems aerodynamics testing and fume hood verification. Low velocity design is very important for the energy efficiency of the air distribution system.

Air pressure in a duct is measured in inches water gauge inches wg. Accu flo nozzle pitot flow station. Ideal for building automation systems bas and hvac applications the design of the airflow sensor allows it to amplify the velocity pressure by a factor of three which in turn allows accurate measurement of low air flow velocities.
