• BSRIA Opens New Airflow Testing Rig

09 October 2023

The Building Services Research and Information Association has announced the opening of a new Airflow Calibration Rig at its North facility in Preston, Lancashire.

This will offer high-precision calibration services for Balometers, commonly known as Flow Capture Hoods. Balometers help to balance indoor airflows, ensuring uniform air exchange throughout spaces and facilitating the consistent removal of pollutants. It measures the flow rate of air leaving or entering a ventilation outlet, and regular calibration is essential to maintain accurate readings.

The facility uses technology based on Orifice Plates in a duct to calculate the volume flow rate. It utilises various inputs, such as local barometric pressure, temperature and humidity, alongside Orifice Plate pressure readings to calculate accurate airflow. This approach leverages the fundamental design parameters adhering to methodologies defined in ISO 5167.

The announcement has received official endorsement from the United Kingdom Accreditation Service (UKAS).

For those wanting to learn more about indoor air quality, BSRIA is hosting a briefing on 17 November 2023 which will explore innovative strategies and technologies aimed at improving air quality in built environments.
