Tracer Gas Airflow Measurement System with High Turndown Ratio

Abstract

Traditional designs for tracer gas airflow measurement systems are cumbersome, can only be used in certain circumstances, and are limited to measuring a relatively narrow band of airflow rates. Researchers at the University of California, Davis have developed a novel method for measuring tracer gas airflow in a number of scenarios with varied bands of airflow rates.

Full Description

Current methods to measure airflow rates in duct systems require careful use and substantial time to produce accurate measurements. Traditional measurement systems use anemometers to measure velocities at several locations in a cross section of an airstream. However, because of the limited detection limits of anemometers, it is very difficult to accurately measure airflow rates when there are large spatial variations in air velocities. This also limits the number of applications for which a particular instrument can be used.

Researchers at the University of California, Davis have developed a unique method to accurately measure tracer gas airflow. This method, unlike others, has been shown to have applications in a wide range of flowrates (50 cfm- 30,000cfm) and in a variety of scenarios. Furthermore, the device allows for a high throughput easily adjustable air flow CO₂ based calibration system.
