What instruments are used to measure the speed and flow rate of the air? What’s the difference?

Air velocity and flow rate are important factors to consider in an HVAC system, especially in the pharmaceutical industry where air quality is critical to the safety of people and products.

There are several options available for measuring air velocity and flow rate, including:

Instruments for measuring air speed

There are several options available for measuring air velocity and flow rate, including:

Anemometer: It is an instrument that uses a small propeller to measure air velocity.

Balometer: It is an instrument that uses a constant airflow to measure the flow rate of air.

Thermistor: This is a component that uses resistance change to measure air velocity.

Pitot measurement: This is a technology that uses differential pressure to measure air velocity.

The differences between speed and range

The main difference between air velocity and flow rate is that velocity refers to the speed at which air moves through a specific point, while flow rate refers to the amount of air that passes through a specific area in a given period of time.

In an HVAC system, it is important to keep the air velocity and flow rate at adequate levels to ensure the quality of the air inside a building. The balometer is a very useful tool for this purpose, as it allows you to measure the air flow rate accurately and reliably.

In conclusion, the choice of instruments for measuring air velocity and flow rate depends on the specific needs of an HVAC system. However, anemometers, balometers, thermistors, and pitot measurement are all reliable tools that can help maintain an efficient and reliable HVAC system in the pharmaceutical industry.
