Air Velocity Measurement | Dwyer Instruments

In air conditioning, heating and ventilating work, it is helpful to understand the techniques used to determine air velocity. In this field, air velocity (distance traveled per unit of time) is usually expressed in feet per minute (FPM).By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time.

Air Velocity an overview | ScienceDirect Topics

Air velocity in a space influences the convective heat exchange between occupant and the indoor environment (Seppanen and Kurnitski, 2013). There are two main types of air velocity or natural air velocity. The first is the air flow caused by natural air flow, buoyancy or mainly atmospheric circulation. In contrast, the second entails air forced air velocity generated by mechanical systems ...

Air Velocity Meters | Instrumart

Air velocity meters use vane, cup, hot wire, or differential pressure technology to measure the speed and/or volume of air movement. They are commonly found in weather stations but are also important tools for analyzing ventilation systems, aerodynamics testing, HVAC balancing, fume hood verification, and other applications in which the movement of air is a primary concern.

Basics of Air Velocity, Pressure and Flow Pressure Sensors

Air velocity can be measured by sensing the pressure produced by the movement of the air. This application note will describe the basic relationships between air velocity and the pressure generated by air flow. Anyone who has put their hand out the window of a moving car has experienced the force applied by moving air. This force can be sensed as a pressure by connecting a tube from the ...

Accurate Airflow Measuring With the FlowStar™ Sensor

The airflow sensor should be able to generate this signal with only 400 to 450 FPM air velocity through the inlet collar. Conventional airflow sensors without amplification capabilities require approximately 700 FPM to generate a inch signal. If 700 FPM represents a 20% minimum condition, the inlet velocity would be 3500 FPM at the ...
