1. When using Emerson quality flow meters, attention should be paid to the impact of the environment. The electromagnetic flow meter of Emerson quality flow meters is often used to measure dirty fluids. After running for a period of time, it often accumulates adhesion layers on the inner wall of the sensor and causes malfunctions. These faults are often caused by the conductivity of the adhesion layer being too high or too low. If the attachment is an insulation layer, the electrode circuit will break and the instrument will not work properly; If the conductivity of the adhesion layer is significantly higher than that of the fluid, the electrode circuit will experience a short circuit and the instrument will not function properly. Therefore, it is necessary to promptly remove the attached scale layer inside the measuring tube of the electromagnetic flowmeter. In addition, lightning strikes can easily induce high branch voltage and surge current in the instrument circuit, causing damage to the instrument. It is mainly introduced through power lines, excitation coils, or flow signal lines between sensors and converters, especially from the control room power lines, which account for the vast majority. Sometimes the operating environment is good and the flowmeter can work normally, but it is easy to overlook the installation conditions (such as poor grounding). In this case, once the environmental conditions change and new interference sources appear during operation (such as welding on pipelines near the flowmeter, installing large transformers nearby, etc.), it will interfere with the normal operation of the instrument, and the output signal of the flowmeter will fluctuate. Therefore, it is necessary to regularly chec
