One end of the liquid guide pipe 2 is a U-shaped structure, and an ultrasonic transceiver structure 4 is provided in the pipeline of the liquid guide pipe 2. A heat meter electronic processing unit 3 is fixedly installed on the outer surface of the liquid guide pipe 2, and the ultrasonic transceiver structure 4 is electrically connected to the heat meter electronic processing unit 3. A mounting hole is provided at the lower arc point of the outer surface of the liquid guide pipe 2, and a temperature sensor 5 (PT100) is installed at the mounting hole. The temperature sensor 5 is electrically connected to the heat meter. The sub-processing unit 3 is electrically connected, and the heat meter can be installed in the heating pipeline when it is working. The hot water first enters the interior of the exhaust tank 1 before passing through the ultrasonic transceiver structure 4, and then enters the interior of the liquid guide tube 2, and then flows along the liquid guide tube 2 and passes through the ultrasonic transceiver structure 4. Since the liquid inlet end of the liquid guide tube 2 is U-shaped, the air mixed in the water can be separated from the water and gathered to the upper end of the interior of the exhaust tank 1, so that the water passing through the liquid guide tube 2 does not contain air, which can effectively improve the ultrasonic transceiver structure 4. When the flowing water does not contain air, the accuracy of the detection data can be effectively improved, and the anti-interference performance of the heat meter can be effectively improved.

[0027] 1 , a feeding pipe 7 and a discharge pipe 8 are fixedly connected to the side surface of the liquid guiding pipe 2. The discharge pipe 8 is located at the lower end of the liquid guiding pipe 2. End caps are threadedly installed at the ports of the feeding pipe 7 and the discharge pipe 8. A control valve 6 is provided at the liquid inlet port of the liquid inlet pipe 9 and the liquid outlet port of the liquid guiding pipe 2. After a long period of work, the control valve 6 on the liquid guiding pipe 2 can be closed first, and then a certain amount of water is injected into the interior of the exhaust tank 1. Then the control valve 6 on the liquid inlet pipe 9 is closed, and then the end cap of the upper port of the feeding pipe 7 is opened. Since the upper end of the feeding pipe 7 is flush with the upper end surface of the exhaust tank 1, there will be no water overflow. Then, a descaling agent is added to the interior of the liquid guiding pipe 2 through the feeding pipe 7, and the descaling agent is used to remove the scale attached to the inner wall of the liquid guiding pipe 2. Then, the end cap of the discharge pipe 8 is opened to discharge the water in the liquid guiding pipe 2 and the exhaust tank 1. This structure can flexibly and conveniently remove the scale in the liquid guiding pipe 2, further improve the accuracy of the detection data, and effectively improve the overall practicality.

[0028] Reference Figure 2 3 , the exhaust valve 10 includes a valve seat 11, a valve core 12 is slidably installed inside the valve seat 11, a valve cover 16 is threadedly installed at the upper end of the valve seat 11, a spring 13 is sleeved on the outer side of the upper end of the valve core 12, one end of the spring 13 is against the inner end surface of the valve cover 16, one end of the valve core 12 is fixedly connected to a slide rod 14, a float 15 is slidably installed on the outer side of the slide rod 14, wherein the exhaust tank 1 can be used to collect air, when the air pressure is too high, the spring 13 is compressed, the valve core 12 is pushed open, and the air inside the exhaust tank 1 is discharged from the exhaust valve 10, when there is too much water inside the exhaust tank 1, when water enters the interior of the exhaust valve 10, the float 15 is raised with the water, and then blocked at the exhaust hole of the valve cover 16, which can effectively prevent water from flowing out of the exhaust valve 10.

[0029] Working principle: When in use, first install the heat meter at the end of the heating pipe, and at the same time install one of the temperature sensors 5 at the liquid inlet port of the heating pipe. At this time, it can be used normally. When working, hot water first enters the interior of the exhaust tank 1 after passing through the ultrasonic transceiver structure 4, and then enters the interior of the liquid guide tube 2, and then flows along the liquid guide tube 2 and passes through the ultrasonic transceiver structure 4. Since the liquid inlet end of the liquid guide tube 2 is U-shaped, the air mixed in the water can be separated from the water and collected to the upper end of the interior of the exhaust tank 1, so that the water passing through the liquid guide tube 2 does not contain air. At this time, the mutual cooperation between the ultrasonic transceiver structure 4 and the heat meter electronic processing unit 3 can effectively detect the water flow between the units in the liquid guide tube 2, and the temperature The temperature sensor 5 can effectively detect the temperature difference in the heating pipe, and then effectively calculate the heat in the heating pipe. After a period of work, first close the control valve 6 on the liquid guide pipe 2, and then inject a certain amount of water into the exhaust tank 1, then close the control valve 6 on the liquid inlet pipe 9, and then open the end cover of the upper port of the feeding pipe 7. Since the upper end of the feeding pipe 7 is flush with the upper end surface of the exhaust tank 1, there will be no water overflow. Then, add a descaling agent to the inside of the liquid guide pipe 2 through the feeding pipe 7, and use the descaling agent to remove the scale attached to the inner wall of the liquid guide pipe 2. Then open the end cover of the discharge pipe 8 to discharge the water in the liquid guide pipe 2 and the exhaust tank 1. This structure can flexibly and conveniently remove the scale in the liquid guide pipe 2, further improving the accuracy of the detection data.
