Requirements for online calibration of pipeline electromagnetic flowmeters

　　Electromagnetic flowmeters are widely used in industry, manufacturing and other industries, and play an irreplaceable and important role in liquid flow measurement. Since the accuracy of flowmeter measurement directly affects the production quality, measurement errors may cause huge economic losses in the production process. Therefore, it is of great significance to study the factors affecting the accuracy of electromagnetic flowmeters, analyze methods to improve measurement accuracy and anti-interference ability during the measurement process.

　　Electromagnetic flowmeter is the main tool for pipeline measurement in my country and has been widely used. In order to meet the objective requirements of social development, it is necessary to have a full understanding of the online calibration requirements of current pipeline electromagnetic flowmeters. The measurement principle of pipeline electromagnetic flowmeters is mainly based on Faraday's law of electromagnetic induction. The main components are sensors and converters. The sensors are generally installed directly on the measured pipeline, and the converters can be connected with the sensors to form an integrated electromagnetic flowmeter. If the connection between the two is achieved through a shielded cable, they will be collectively referred to as separate electromagnetic flowmeters.

　　Its online calibration is mainly carried out through the electrical parameter method and the standard table method. Regardless of which calibration method is used, it must be carried out in accordance with local specifications and industry standards. This article conducts a detailed analysis of this, hoping to promote the improvement of the online calibration quality of pipeline electromagnetic flowmeters.
