What should we pay attention to when installing the prepaid IC card water meter

Smart IC card water meters have many functions that mechanical water meter do not have, so many new buildings use them to replace traditional water meters. Then, those aspects should be paid attention to when installing smart IC card prepaid water meters. 1. Please pay attention to the cleanliness of the pipeline. IC card prepaid water meter needs to be connected to a water pipe, so the pipe must be cleaned before installing the water meter. Especially the scum in the pipeline, such as rust, cotton fiber, stones, etc., so it is best to clean the scum before installing the water meter. 2. Keep away from interference sources. IC card prepaid water meter is a smart device controlled by a precision system, so the installation site should be far away from vibration interference, electromagnetic interference, noise interference and other interference sources to ensure the accuracy of water meter measurement. 3. Confirm the same pipe diameter. Make sure that the pipe diameter of the water pipe matches the diameter of the water meter during installation. In addition, in order to prevent inconvenience in installation due to inconsistent diameters, rubber gaskets with the same diameter should be used between connections.
