Common failures in the use of electromagnetic flowmeters are caused by damage to the components of the instrument itself, or caused by improper selection, improper installation, environmental conditions, fluid characteristics, and other factors, such as display fluctuations, reduced accuracy, and even instrument damage . It can generally be divided into two types: faults that occur during installation and commissioning (failures during commissioning) and faults that occur during normal operation (faults during operation).
The electromagnetic flowmeter is composed of a transmitter and a converter, and the two are connected to each other with connecting wires (including excitation wires and signal wires). The transmitter works based on the law of electromagnetic induction. As shown in Figure 1, the measured medium flows perpendicular to the direction of the magnetic lines of force. Therefore, an induced electromotive force ex is generated in the direction in which the medium flows and the lines of magnetic force are perpendicular.
