Research on Flow sensor of Ultrasonic Gas Meter

Abstract

By reviewing the development of gas meter, the application prospect of ultrasonic gas meter is forecasted, the key technology and research and development difficulties of ultrasonic flow sensor, as well as the key application technology problems to be solved are discussed. The paper focuses on the design and selection of timing scheme of flow sensor, design of flow field characteristics of flow channel of flow sensor, electro-acoustic performance of flow sensor, linearity and repeatability of gas flow sensor. Through the exchange of theoretical research and practical application experience, the promotion of ultrasonic sensing technology, so as to promote the batch production and application of ultrasonic gas meters.
