In this two-minute video, David demonstrates how to set up a balometer capture hood for testing a ventilation system. For demonstration purposes, David uses the TSI Alnor Balometer EBT731.
A balometer identifies opportunities for improving air flow distribution within a duct system. A balometer can identify the source of indoor air quality issues as well as comfort issues relating to improper ventilation.
A balometer will give you a digital readout as well as an analog. On the side of the instrument is a red button that will lock the reading into place. So, once you’ve taken a reading, you can bring the instrument down to see the reading easier.
The TSI Alnor EBT731 capture hood is used to take direct air volume readings at diffusers and grilles. The detachable digital micromanometer and optional probes makes it suitable for a wide variety of measurement applications.
A velometer is an accelerometer with an analog signal integration circuit. The device provides a voltage reading based on the air velocity in an area.
Flow hoods—also called balometers–are used in the HVAC industry to measure the air flows at registers.
To balance your HVAC airflow, here are a few things you can try:
