Abstract
The invention relates to an ultrasonic correlation-type water meter. A water inlet of a water meter body (1) is parallel to a water outlet of the water meter body (1), and the water meter body (1) is perpendicular to a measurement passage. An upper ultrasonic transducer (2) and a lower ultrasonic transducer (3) are connected with an ultrasonic timing module (4) through signal lines, and the lengths of connecting lines are equal. The ultrasonic timing module (4) is controlled by a single-chip microcomputer (5). Parameters such as flow velocity, flow rate and the accumulated flow rate of the water meter are displayed through a liquid crystal display module (6). The flow velocity of water is acquired through a time-difference method, and measurement accuracy will not be affected by the fair current or counter current of the water.
