Research on Ultrasonic Measurement of Residential Gas Meter

摘要

Ultrasonic Gas Flow Meters have been used in the flow measurement for high flow rate gases.In order to develop the technology of Ultrasonic Gas Meters this paper is going to focus on the residential gas measurement by using ultrasonic wave with transit time-differential technology.The paper mainly consists of the following parts: reasoning an applicable formula for measuring residential gas flow; analyzing and designing the shape and the form of measuring sound transmit path and analyzing the design outlines of the circuits.
