Project overview

Gas Composition Measurement using Ultrasonic Sensors

Traditional methods to determine the composition of gas mixtures have several deficiencies, including higher price, slow response, tricky calibration, etc. As an alternative, ultrasound-based technique is not only very accurate and sensitive, but also much cheaper. Moreover, it avoids the tricky calibration.

This project is aimed at measuring speed of sound in binary or ternary gas mixtures, and then figuring out the composition by using appropriate models.
