[0002] As the shortage of water resources becomes increasingly prominent, improving the accuracy and intelligence of water meter measurement has become the current development trend. Ultrasonic water meters have advantages that other water meters cannot match, such as small starting flow, high accuracy, wide range ratio, and easy maintenance, which all meet the new standards of modern measurement. In the modern society where information technology is developing rapidly, the use of ultrasonic water meters combined with electronic communication technology can enable water companies to achieve a qualitative leap in economic benefits, social benefits and scientific management level.
[0003] The structure of an ultrasonic water meter generally consists of a measuring pipe at the bottom and a meter housing installed on the measuring pipe. The specific method of measuring water flow is to install ultrasonic transducers at both ends of the measuring pipe, transmit ultrasonic waves at one end, and receive ultrasonic signals at the other end, and then feed the signal data back to the processor inside the meter housing to obtain the water flow. In the current installation structure, the ultrasonic transducer lines at both ends of the measuring pipe are directly connected from the outside of the pipe to the meter housing, and the cables are exposed, lacking reliability and having poor appearance quality.

With the above structure, the ultrasonic transducer cable is constrained, and the smooth surface can reduce cable wear.
[0011] Preferably, the measuring pipe has a thickened structure at a position corresponding to the circular channel, and the thickened structure is trapezoidal. The above structure can enhance the strength of the pipe and compensate for the low wall strength of the measuring pipe caused by the transverse channel.
[0012] As a preferred embodiment, the end of the measuring pipe is equipped with an end cover, and the end cover is arranged on the notch and the arc-shaped groove section. The above structure is adopted to protect the ultrasonic transducer.

With the above structure, the water meter mounting threads cooperate with the nuts to firmly mount the meter housing.
[0015] As a preferred embodiment, a sealing ring installation groove is provided at the shaft shoulder of the installation column, and a sealing ring is installed in the sealing ring installation groove. With the above structure, the inside of the meter head housing is sealed and protected to prevent water from entering under special circumstances and causing damage to the water meter.
[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: a vertical channel is provided inside the mounting column, the lower part of the vertical channel is connected to the transverse channel on the measuring pipe, the ultrasonic transducer circuit enters the water meter assembly in a fully enclosed manner through the transverse channel and the vertical channel in turn, without any exposure, which can make the water meter more beautiful and improve safety and reliability.
