Technical Field

The utility model relates to a transducer structure for improving water measuring precision, and belongs to the technical field of ultrasonic water measuring.

Background

Two modes, namely a weir trough water level method and a flow velocity area method, are generally adopted in the current stage of open channel water surveying.

The flow rate area method is to determine the flow rate by measuring the flow rate of a water passing section and the area of the water passing section, generally, a radar or a Doppler current meter is used for measuring the surface flow rate, and the lower-layer flow rate is estimated through a fluid formula, so that the accuracy cannot be ensured.

The ultrasonic layered flow measurement speed is combined with a water level and an overflowing area to calculate flow, the mode is generally an ultrasonic matrix structure, but the ultrasonic transducer structure is generally a cylinder-like body, and a transmitting surface is perpendicular to the cylinder, so that the ultrasonic transducer in the measuring box generally protrudes out of a side wall or a pit exists on the side wall, and the fluid state and the flow measurement precision are influenced under any condition. Therefore, the prior art can not meet the use requirements of people.
