Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic water meters, in particular to a novel coaxial ultrasonic water meter. Background Art

[0002] Ultrasonic water meters do not wear out during use because they have no mechanical rotating parts. Ultrasonic water meters also use non-contact measurement to measure water flow by emitting ultrasonic signals and receiving echoes, which means that they do not need to physically contact the water flow, will not affect the water quality, and reduce the possibility of wear and blockage.

[0003] However, the existing ultrasonic water meters are large in size, not convenient to install, and the pipes need to be disassembled during maintenance. Considering that the coaxial water meter adopts a coaxial structure, the water inlet and the water outlet are designed on the same axis, so that the volume of the entire water meter is relatively small, easy to install, and saves space. In addition, a coaxial manifold is installed on the pipeline, so that when replacing the metering mechanism, the user's pipeline does not need to be disassembled, which is convenient for the user to replace and update the water meter. Therefore, the utility model considers the development of a coaxial ultrasonic water meter. On the one hand, the coaxial structure is used to improve the installation efficiency, and on the other hand, the ultrasonic measurement method is used to improve the detection accuracy.
