What types of faults can occur during the calibration period of insert-type electromagnetic flowmeters? There are also faults related to the initial calibration of split-type electromagnetic flowmeters, but once these faults are resolved, they generally do not reoccur under the same conditions. Common faults are mainly related to the installation and commissioning period, with environmental interference and the effects of fluid properties being the three main causes. For tasks such as pipeline system installation, common faults arise from incorrect installation locations of electromagnetic flow meters; for example, flow meters are installed in natural gas pipeline networks where it is easy to accumulate high levels of residue ； The insert-type electromagnetic flowmeter sensor experiences no pressure; the liquid flows directly into the atmosphere, thus forming a complete measurement tube ； Installing a flow meter in the space that may arise due to dirt on the vertical lines is special, as it is located underwater, to ensure there is no floating. Factors such as the environment, stray current interference from main pipelines, spatial electromagnetic wave interference, and magnetic field interference from large motors – for stray current interference from pipelines, good grounding practices usually yield satisfactory measurement results; however, this approach does not work in cases where there is a high level of stray current (such as in electrolysis plant production lines), and special measures involving the use of insert-type electromagnetic flowmeter sensors positioned at the pipeline edges are necessary. Introduction to electromagnetic wave-space signal cables: they usually have one or multiple shielding layers for protection, but there are cases where such shielding cannot overcome certain issues. Fluid liquids contain tiny bubbles that are usually evenly distributed and do not affect normal measurements; this is only the case with volumetric flow rates where liquids and gases are combined ； Bubbles increase the fluctuations in the output signal. If large bubbles cover the entire electrode surface through which the current flows, causing the electrode’s signal to momentarily break the circuit, the output signal will experience significant fluctuations. Rectangular-wave excitation split-type electromagnetic flowmeters operating at low frequencies (50/16 Hz to 50/6 Hz) generate noise when measuring slurries containing a certain amount or more of solids in the liquid, and the output signal also experiences some degree of fluctuation.
