There are many error factors that may occur in the process of verifying the water meter. What errors will the water meter have during the verification process?
We now analyze the structure of the water meter itself, the material and processing of the water meter parts, the assembly of the water meter, the verification device of the water meter, the human operation, and the verification environment.
First of all, the quality of the water meter is not good enough. The water meter is a relatively high-precision measuring instrument. Whether the water meter has a high verification level will largely depend on the quality of the various components inside the water meter. At present, the types of water meters are very complicated, and there are also great differences in materials and operating mechanisms. If the selected water meter materials and assembly processes have insufficient compatibility, it will inevitably have an adverse effect on the accuracy of water meter verification. In the process of water meter parts assembly and overall structure assembly, if the assembly process is not correct, it will also affect the accuracy of water meter verification. For example, there are a large number of unpolished metal business cards in the parts, the unsatisfactory meshing state of the gears, and the unreasonable tightness of the water surface, all of which will have an important impact on the water meter verification results.
Secondly, the water meter verification device will also have a key impact on the accuracy of the verification results. For the error factors caused by the verification device, part of the reason is that the quality of the verification device itself is not good enough, and there are abnormal performance problems in actual operation; the other part is the verification error caused by the environment of the verification device. The quality of the surrounding environment of the verification device has relatively highly sensitive parts. Under normal circumstances, the verification device needs to be in a relatively dry environment, such as low air temperature and good ventilation. However, once the environment around the verification device lacks light exposure for a long time, Poor ventilation and high air humidity will cause errors in the verification device.
Secondly, the error is caused by external environmental factors. In addition to ambient humidity, ventilation effect, and light intensity, the ambient temperature will also have a great impact on the accuracy of water meter verification. When the ambient temperature is below the freezing point or above 30°C, it will have a more obvious impact on the water meter verification results. This requires strict control of the ambient temperature around the verification device. When the water supply pressure is unstable, it will also have a more obvious impact on the accuracy of the water meter verification. In addition, the quality of the water supply will also have a key impact on the accuracy of water meter verification. Once the water quality is not up to standard, such as too much algae, floating objects, and other impurities in the water, it will significantly interfere with the water meter verification results, resulting in a decrease in the accuracy of the verification results.
The personnel does not pay enough attention to the water meter verification work, and there are phenomena such as illegal operations in the actual verification process, which will directly lead to inaccurate verification results. For example, the residual air in the water supply pipes and water meters could not be completely exhausted before the verification work started. In addition, there are individual operators who are not meticulous in their work. During the water meter verification process, they neglected the operation inspection and maintenance management of related facilities and equipment. Many parts have aging problems, but they have not been effectively dealt with. These factors will lead to water meter verification. An error occurred in the process. Even individual operators are eager to complete their work tasks in order to cope with the work. When transcribing the verification values, there are transcription errors, which will also cause the accuracy of the water meter verification results.
