Influencing factors of measurement accuracy of smart water meters
The measurement accuracy of smart water meters is very important, whether it is from the long-term protection of water resources or from the interests of users. Accurate measurement can control water consumption, thereby better protecting water resources and benefiting human development; accurate measurement can guarantee the interests of users and allow people to pay water fees with confidence. Do you know what factors affect the measurement of smart water meters, and what should water meter users do?
The choice of smart water meter caliber is the premise. The caliber of the water meter should be selected according to the water consumption of the water users. It is advisable that the water consumption is close to the common flow rate of the selected caliber, and avoid too large or too small. If it is small, the water meter will be overloaded, and the gears will be easily worn, which will affect the measurement accuracy. Therefore, before purchasing a water meter, users must understand the caliber of the water meter used, or the caliber of the pipe.
The installation of smart water meters should not be underestimated. The installation of the water meter should be installed in strict accordance with the local installation standards. The installation location should be strictly prohibited from being close to septic tanks, sewers and other places that are prone to sewage pollution, as well as places with large vibrations such as roads, and the water meter wells are well drained and not easy to get wet. The installation technology includes that the water meter cannot be tilted, there should be enough straight pipe sections at both ends of the water meter, the distance between the meters should not be too short, and the sundries should be removed before the water meter is installed. It is recommended to install meters in the community or where the water meters are more concentrated. Installing a water meter box for the water meter can not only protect the water meter from wind and rain, but also have relatively stable performance in metering and other aspects, and at the same time have a certain anti-theft effect.
Regular replacement of smart water meters is the key point. After the water meter has been used for a period of time, due to the influence of uncertain factors such as the environment, pollution, water quality, water consumption, and pressure fluctuations, the movement of the water meter will be worn and the gap will increase, resulting in a decrease in measurement accuracy and even an increase in error. Table is an important means to solve this problem. The use time of household water meters is 6 years, and the use time of industrial water meters is 4 years.
Regular testing of smart water meters is the key. The sensitivity of the water meter directly affects the measurement accuracy of the water meter, and the long-term wear and tear of the water meter movement greatly reduces its sensitivity. Therefore, it is recommended that the maintenance of the periodic table movement is mainly based on replacement. The sensitivity of the water meter movement is an important indicator for verifying the measurement accuracy of the water meter. Only when the sensitivity meets the requirements can it be allowed to continue to be used.
The state stipulates that small-caliber smart water meters should be tested every two years and replaced every 4-6 years. There is a certain basis for use. Many users have certain resistance to regular testing and replacement of water meters. The various measures taken above are mainly from the perspective of water meter users. Regular detection and replacement of smart water meters not only ensures its good measurement accuracy, but also provides protection for users' drinking water safety.
