Air Flow Measurement

Using the right tools and the right process can simplify what may otherwise seem a daunting process.

Air flow measurement.

The newest microprocessor based instruments complete duct hvac air flow measurement data collection accurately even before the patience of the hvac tech wears out. Air behaves in a wave like manner meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Read the screen on the bottom of the hood to get your measurement. Some can even detect the wind direction.

It will look like a square or rectangular piece of metal with slats running across it. You ll typically find the exhaust fan grille on the ceiling. We include examples of manufacturer s air flow rate or cfm data for hvac equipment like air conditioners and furnaces. The primary cause of airflow is the existence of air.

Make sure air is not able to escape from the top of the hood as this will make your air flow measurement less accurate. You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters. Air flow rate data. Airflow or air flow is the movement of air.

Airflow instruments are accurate high quality professional grade instruments used by a wide range of customers including building service contractors commissioning specialists facility engineers and research professionals. When selecting an airflow measurement instrument it is important to consider your application. Especially with respect to iaq requirements for minimum ventilation of occupied spaces the need for accurate reliable air flow measurement is a must have. An air flow meter measures air velocity as well as air pressure.

At tsi precision measurement devices are our specialty and our line of air flow measurement instruments is unbeatable in terms of accuracy. This article defines air flow rate or cubic feet per minute cfm as the term is used to describe building air conditioners heating systems or building air movement rates. Measuring air flow with anemometers has been limited in the past by time. Measuring airflow is easy measuring airflow accurately however is a challenge.

The newest microprocessor based anemometers complete duct air flow measurement data collection accurately even before the patience of the hvac tech wears out. Atmospheric difference atmospheric air pressure is directly related to altitude temperature and composition. Achieve precision flow measurement and process control flow measurement is the process of measuring fluid in your plant or industry. Depending on the type of application the air flow meter is made as a hot wire air flow meter a vane air flow meter a cup anemometer a pitot tube air flow meter or a pocket weather flow meter all of which can measure air velocity as well as air pressure.

The more precise question is how to acquire the average flow rate. We offer two methods of hvac air flow measurement differential pressure and thermal dispersion giving you the option to choose how you measure your hvac air flow.
