Water Supply Metering (Hefei Electromagnetic Water Meter) Case

Company：Hefei Water Supply Group Co. LTD
Project：Hefei Water Supply Group 2021-2023 electromagnetic water meter fixed supplier procurement items
Project background：In order to facilitate the design, planning and organization of construction of the new project, Hefei Water Supply Group chooses the intelligent electromagnetic water meter with remote transmission function to realize the online monitoring and data analysis of water consumption. Based on the real-time online monitoring of the flow, pressure and water quality of each zone through the zoning measurement of the water supply network, it calculates and analyzes the minimum flow at night by combining the transmission data. The minimum flow at night is less affected by seasonal changes. Through the analysis of the minimum flow at night, the reported or unreported leakage water can be identified to assist leak detection personnel to optimize leak detection procedures and improve the efficiency of pipe network operation and maintenance management. In addition, through real-time monitoring of water supply flow, the areas with possible leakage points can be analyzed and identified in advance. Thus prevention in advance, timely control, effectively reduce pipe network leakage rate, improve water supply efficiency, and save precious water resources.
Project requirement：It can accurately measure the large flow rate at peak and small flow rate at night, and the remote data can be compatible with various software platforms of the company. In some working conditions, the installation mode without straight pipe section should be adopted, which can be used in harsh downhole environment for a long time. The sensor adopts all-pass structure, zero pressure loss, no wear; Large scale ratio is conducive to water supply enterprises to improve water supply recovery rate, reduce leakage rate and improve water resource utilization efficiency.
Special needs：
Product application：A+K electromagnetic water meter has the characteristics of wide range, low initial flow rate and high precision. Drip measurement is more suitable for non-resident users' trade settlement and DMA cell night minimum flow monitoring. There are pressure and remote transmission modules available for users to choose, and its own remote transmission module can realize fast docking with the three-party system. At present, the ETFE spraying technology, compared with the traditional rubber and PTFE lining process, has obvious advantages in acid and alkali resistance, corrosion resistance, anti-chapping, anti-falling, friction resistance, impact resistance, no scaling, long life and so on. Its theoretical service life is as long as 30 years. The most important is: the use of ETFE lining coating process, due to the liquid connection area is hundreds of times larger than rubber or tetrafluoride lining, its grounding performance and lightning protection function has been geometrically improved.
Customer evaluation：Installation condition requirements are low, accurate and reliable measurement, professional service level.
