How To Ensure the Accuracy of Smart Water Meters?
The accuracy of smart water meter measurement is a common concern of water users and water suppliers. Because the number of smart water meters is high or low, it will affect the interests of different parties. At the same time, accurate measurement can urge users to control water consumption to a certain extent and save water resources. Therefore, in order to ensure the interests of users and protect water resources, the accuracy of smart water meter measurement is extremely important. So, what should users do to better ensure the accuracy of the smart water meter when using the smart water meter?
The first is to choose different types of smart water meters according to different use environments when purchasing. Among them, the diameter of the water meter is an important parameter to be considered when purchasing, and the appropriate diameter should be selected according to the water consumption. For example, the industrial water consumption is relatively large, and the diameter of the drainage pipe is generally relatively large. Therefore, if the diameter of the water meter is too small, it is easy to cause the wear of the water meter gear due to overloading. For civil water, the diameter of the water meter is too large, and the water consumption of small flow will be difficult to measure. Therefore, when purchasing a smart water meter, you must first confirm the diameter of the water meter and the diameter of the pipe.
Secondly, the installation of water meters should be strictly implemented in accordance with the requirements of the national standard GB/T778.2-1996. Before the water meter is installed, the sediment in the pipeline should be emptied to prevent the water meter from being blocked. Clear the water flow direction of the water meter to prevent reverse installation. The installation location should be considered to avoid corrosive places and places with poor drainage. A check valve should be added behind the installed water meter to prevent the backflow of water in the pipeline behind the meter, which may damage the water meter or contaminate the water supply network. The above operations are to try to avoid the blockage of the pipeline due to impurities and other reasons, resulting in internal damage to the water meter, resulting in total measurement deviation.
Furthermore, the service life of smart water meters will also affect the measurement. At present, the lifespan of water meters on the domestic market is generally 6 years for civil use and 4 years for industrial use. If it exceeds this period, it is recommended to replace it in time. Because the smart water meter is used for a certain period of time, due to the influence of uncertain factors such as the quality of the environment, the degree of water pollution, the size of water consumption, etc., the movement and wear of the water meter will be caused, and the measurement accuracy will be reduced.
The above describes how to ensure the accuracy of the smart water meter from three aspects: the size of the smart water meter diameter, installation points, and service life. With the development of science, new smart water meters continue to appear, and the application of technologies such as remote control and remote meter reading is becoming more and more common. This requires us to continuously improve the management level, from the selection and installation to dynamic management to ensure the accurate measurement of the water meter, so as to ensure the fairness of the interests of all parties.
