N2 - Based on the transit-time ultrasonic gas flowrate measurement principle and the model-fitting method, a model-based Time-of-Flight measurement method is proposed. A single acoustic path ultrasonic gas flow measurement system is developed and an empirical model of the ultrasonic detection signal is established. The least-squares curve fitting criterion and the modified steepest descent method are introduced to implement the optimal Time-of-Flight estimation. Static and dynamic experiments are carried out respectively in a pipe with the inner diameter of 100.0 mm. The preliminary experimental results verify the feasibility of the new model-based ultrasonic gas flow measurement method and show that the measurement performance of the gas flowrate measurement system is satisfactory.
