1. When choosing a large-caliber IC card intelligent water meter, the flow rate of the pipeline frequently used should be close to or less than that of the water meter, and the caliber of the water meter can not be determined simply by the caliber of the pipeline.
2, the new pipeline should first remove the gravel, sediment and other debris in the pipeline before the installation of large caliber IC card intelligent water meter, in order to prevent large caliber IC card intelligent water meter damage or failure. You are advised to install a filter.
3, large caliber IC card intelligent water meter dial upward horizontal installation, the arrow direction of the case should be consistent with the direction of water flow in the pipeline, water meter upstream should be installed flow straightening device or rectifier straight pipe section, rectifier straight pipe section length is greater than 5 times the caliber of the water meter.
4, large caliber IC card intelligent water meter should not bear excessive stress caused by the pipe, when necessary, the water meter should be installed on the base or bracket.
