Abstract
The invention discloses an ultrasonic wave opposite irradiation type water meter. The ultrasonic wave opposite irradiation type water meter is structurally characterized in that two opposite irradiation type energy converters are installed inside a water meter body, a measurement tube is connected between the two opposite irradiation type energy converters, and the two opposite irradiation type energy converters are completely attached to the tube wall of the measurement tube. The front ultrasonic wave energy converter and the back ultrasonic wave energy converter are connected with an ultrasonic wave timing module through signal lines, the connection lines are the same in length, the ultrasonic wave timing module is connected with a single chip microcomputer, and the single chip microcomputer is connected with a liquid crystal display module. The ultrasonic wave opposite irradiation type water meter has the advantages that two opposite irradiation type energy converters perform direct opposite irradiation measurement, so paths for sound wave transmission are shortened, losses for sound wave transmission are reduced, 100% sound wave opposite irradiation can be achieved, and measurement is more accurate and product quality is more stable accordingly; streamline type appearance is adopted in the opposite irradiation type energy converters, the opposite irradiation type energy converters can be completely attached to a tube section of a basic meter, so water resistance is reduced, turbulent flow is quite small, and through measurement tube rectification, measurement errors are small.
Description
