[0025] In existing ultrasonic water meters, the transducer is generally installed at the top of the pipe section, and the water flow directly passes through the lower pipe section. This installation method causes the ultrasonic signal emitted by the top transducer to be affected by air bubbles, and the medium through which the ultrasonic signal travels during the measurement process cannot be completely unified, affecting the measurement accuracy.

[0026] Therefore, referring to Figures 1 to 4 , the present utility model provides a side-mounted transducer ultrasonic water meter, including an ultrasonic pipe section 1. A set of transducer sleeves 11 are symmetrically arranged obliquely on the side wall of the ultrasonic pipe section 1. A plug rod 2 is embedded in the transducer sleeve 11, and a transducer assembly 3 is embedded in the plug rod 2. The transducer assembly 3 includes a ceramic wafer 31 and a plug rod cover 32. A rubber gasket 33 is embedded between the ceramic wafer 31 and the plug rod cover 32. A measuring pipe 4 is embedded in the ultrasonic pipe section 1. The ceramic wafer 31 and the reflecting mirror 41 correspondingly arranged in the measuring pipe 4 face each other directly. The ultrasonic signal emitted by the ceramic wafer 31 is reflected by one end reflecting mirror 41 and transmitted horizontally in the ultrasonic pipe section 1 to the other end reflecting mirror 41. Fixing screws 5 are screwed on the transducer sleeves 11, and a backing plate 6 is embedded between the fixing screws 5. A water meter assembly 7 is arranged on the backing plate 6.

[0027] It should be noted that the water meter assembly 7 adopts a conventional ultrasonic water meter assembly, including a housing. A junction box for installing a transfer board and a battery for power supply are arranged in the inner cavity of the housing. An electrical box for installing a circuit board is arranged on the top of the housing. A wide-screen transparent bracket is arranged on the top of the electrical box, and a housing cover is arranged on the wide-screen transparent bracket. The transducer assembly 3 is signal-connected to the transfer board, and the transfer board is signal-connected to the circuit board.

[0028] Among them, participating Figure 2 and Figure 3 , a set of buckling rings 32a are arranged on the end wall of the plug rod cover 32, and a set of corresponding buckling parts 21 are arranged on the end wall of the plug rod 2. The buckling parts 21 buckle the corresponding buckling rings 32a to complete the fixation of the plug rod cover 32 and the plug rod 2.

[0029] Additionally, it should be noted that the main body of the plug rod 2 is made of plastic, which has a lower cost.

[0030] Among them, a set of plastic explosion-proof parts 12 are also arranged at the bottom of the ultrasonic pipe section 1, and the plastic explosion-proof parts 12 block the bottom pipe opening of the ultrasonic pipe section 1.

[0031] Among them, the plastic explosion-proof part 12 is a plastic plug, and a sealing O-ring is arranged on it.

[0032] When the environmental temperature is relatively low, the water in the pipe section is likely to freeze. The setting of the plastic explosion-proof part 12 can prevent the pipe section from being burst by ice, effectively preventing the occurrence of freezing and bursting.

[0033] Among them, a sealing O-ring is arranged between the fixing screw 5 and the transducer sleeve 11.

A limiting hole 42 corresponding to the sleeve hole 14 is arranged on the measuring pipe 4. The small sleeve 8 and the wire pressing sleeve 9 are inserted into the sleeve hole 14 and the limiting hole 42 in cooperation.

[0036] It should be additionally noted that the cooperation between the small sleeve 8 and the wire pressing sleeve 9 can, on the one hand, play a certain limiting role. On the other hand, since it is a hollow hole inside, generally a temperature sensor or the like is installed in the hole to measure the temperature condition inside the pipe section and the like.

[0037] Among them, a sealing O-ring is arranged between the small sleeve 8 and the wire pressing sleeve 9.

[0038] Refer to Figure 4 , during the use process, the adapter plate sends out a signal instruction. The ceramic wafer 31 in the transducer assembly 3 emits an ultrasonic signal. One end mirror 41 reflects the ultrasonic signal and transmits it horizontally in the ultrasonic pipe section to the other end mirror 41, thereby completing the measurement of the flow rate.

[0039] The utility model provides a side-mounted transducer ultrasonic water meter. Compared with the traditional installation scheme, the utility model creatively adopts a structure with side-mounted transducers. In the side-mounted structure, one end mirror reflects the ultrasonic signal emitted by the ceramic wafer and transmits it horizontally in the ultrasonic pipe section to the other end mirror. The transmission medium passed by the ultrasonic signal is all water, which ensures the constancy of the medium during the transmission process and avoids the influence of air bubbles at the top of the pipe section. It ingeniously solves the problem that in the existing ultrasonic water meter, when the transducer is installed at the top of the pipe section, the ultrasonic signal emitted by the top transducer is affected by air bubbles, and the medium through which the ultrasonic signal travels during the measurement process cannot be completely unified, affecting the measurement accuracy.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit them.
