What are the reasons for errors in the verification process of electronic remote water meters?
Many people have found that errors will occur in the verification process of electronic remote water meters. What are the reasons? In fact, the occurrence of errors has a lot to do with the water meter itself, the external environment, and human use. Why do you say this? Let's analyze it carefully.
On the whole, the main reasons for errors in the verification of electronic remote water meters are as follows:
1. Errors caused by the water meter itself
First of all, the quality of the water meter itself is not good enough. Since the water meter is a high-precision measuring instrument, it can have a high level of verification, which is directly related to the quality of the accessories used inside. At present, the types of water meters are complex, and the operating mechanisms and accessories used inside are also very different. , If there is a mismatch between the water meter material selected by the manufacturer and the assembly process itself, it will inevitably lead to a decrease in the accuracy of the water meter verification.
In the assembly process of the whole structure of water meter accessories, if the assembly process is not correct, it will also affect the accuracy of the water meter verification. There is a large error in the verification.
Secondly, the water meter verification device will also affect the accuracy of the verification results. The error caused by the verification device mainly has two parts, one of which is due to the poor quality of the verification device itself, resulting in certain abnormal performance during the actual operation process, and the other part is caused by the environment in which the verification device itself is located. verification error.
The verification device has a certain sensitivity to the surrounding environment. If it is in a good environment, such as low air humidity and good ventilation, then the accuracy of the verification device is relatively high. On the contrary, if the environment around the verification device is not good, then There will also be errors in the test results.
2. Errors caused by external environmental factors
External environmental factors mainly include environmental humidity, ventilation effect, light intensity and environmental temperature, these environmental factors will affect the accuracy of water meter verification. If the ambient temperature is above 30°C and below 0°C, there will be certain errors in the verification results, which requires us to strictly control the ambient temperature of the verification device during verification.
In addition, when the water pressure of the water supply is in an unstable state, it will also lead to a decrease in the accuracy of the verification. At the same time, the water quality of the water supply will also affect the accuracy of the water meter verification. Once the water quality is relatively poor, for example, the water contains a lot of floating objects, these floating objects will interfere with the results of the water meter verification.
3. Errors caused by human subjective factors
When the water meter is verified, the operator's own technical level and business ability also affect the verification result. If the operator does not operate correctly, it will inevitably affect the verification result. Some operators do not pay attention to the verification work. During the actual operation, there are illegal operations, which may lead to inaccurate verification results. Before the verification work, the residual air from the water pipes and water meters is not collected and discharged, which will affect the verification results. accuracy.
In addition, some operators did not work carefully during the verification and neglected the maintenance of related equipment. Some equipment was already aging during the inspection, and these aging equipment were not dealt with in time, resulting in errors in the verification process. In order to rush to complete the work, there are also some operators who make mistakes in copying the verification values, which will also lead to errors in the verification results.
It can be known that there are many reasons for errors in the verification process of electronic remote water meters, among which the water meter itself, external environmental factors and human subjective factors are the main reasons for the large errors in the verification results.
