The advantages of intelligent electromagnetic flowmeters are recognized throughout the industry. However, many users do not experience these advantages in practice after purchasing them. In fact, to fully utilize the benefits of intelligent electromagnetic flowmeters, it is necessary to follow the installation instructions carefully, and scientific data management must also be implemented during subsequent maintenance. 1. Regarding the installation of intelligent electromagnetic flowmeters: ① There should be a certain length of straight pipe section in front of and behind the sensor of the intelligent electromagnetic flowmeter; the requirements for this distance are not as strict as those for vortex flowmeters. At least, the upstream straight pipe section should be at least 5D in length (where D is the diameter of the pipe), while the downstream straight pipe section should be at least 2D long. ② It is necessary to avoid installing intelligent electromagnetic flowmeters on pipes that are subject to severe vibrations, to prevent measurement errors ； ③Avoid installing intelligent electromagnetic flowmeters in areas with strong interference sources, to prevent electromagnetic interference ； ④1. The fluid within the pipe must fill the entire pipe, that is, it should be in a fully filled state. For specific instructions on how to install intelligent electromagnetic flowmeters, refer to: “How to Install Electromagnetic Flowmeters Correctly”. 2. Data maintenance over time: ① Due to the long-term operation of intelligent electromagnetic flowmeters, a large amount of data is generated; therefore, it is necessary to create a separate database for these flowmeter records. This database can include information such as the manufacturer, model, date of production, installation environment and location, pipe diameter, and the time when the instrument was calibrated ； ②The operating condition of intelligent electromagnetic flowmeters should be checked regularly, and testing and calibration should be carried out; generally, the following two methods can be used for such testing and calibration ； 3. Finally, compare and analyze the data obtained from testing and calibration with previous data. If any suspicious differences are found between the two sets of data, it is necessary to identify the cause of such discrepancies and address them. After resolving the issues, prepare a report analyzing the performance of the instrument. In summary: To ensure the efficient operation of intelligent electromagnetic flowmeters, careful attention must be paid to their selection, installation, and maintenance; carelessness must be avoided, as it can otherwise lead to unnecessary financial losses.
