[0001] The utility model relates to ultrasonic water meter technical field, especially a kind of high-precision ultrasonic water meter. BACKGROUND

[0002] With the continuous development of industrial economy and city scale, water meter as the instrument for measuring water flow is being more and more widely installed and used in industry and residential life. With the development of technology, electronic water meter is increasingly used in production and life, and ultrasonic water meter is a new type of water meter that calculates the flow rate of water by detecting the time difference generated by the change of speed when ultrasonic sound beam propagates downstream and upstream in water, and analyzing and processing the flow rate of water to further calculate the flow of water.
