The first type of electromagnetic flowmeter malfunction in the instrument itself, namely the failure of the instrument structure or component damage; the second category is caused by external causes of failure, such as improper installation of flow distortion, deposition and scaling, etc. . Here is a discussion of the application and the above second category of external causes of failure. In accordance with the classification of the time of the failure, can be divided into: ①commissioning of the fault; ② run-time fault. Debugging fault appears in the initial installation after commissioning, the main reason is the improper selection or improper installation, installation and so on. Run-time fault foot in operation after a period of time, mainly due to impurities in the fluid electrode attached to the liner, changes in environmental conditions, new sources of interference and so on. According to the source of the external fault analysis from three aspects: ①pipeline system and installation caused; ② caused by the environment; ③ fluid caused. Source ①is mainly shown during the commissioning period; sources ② and ③ both occur during the commissioning and operation periods. First, the commissioning of the fault This type of fault in the initial installation of the electromagnetic flowmeter used to appear when debugging, but improved troubleshooting, after the same conditions in general will not appear again. Common debugging problems mainly improper installation, environmental interference, fluid characteristics of the three reasons. 1, the piping system and installation are usually caused by improper installation of electromagnetic flow sensor fault, the common example of the flow sensor installed in the gas pool is easy to accumulate gas pipe network high point; flow sensor without back pressure, liquid 迳 straight row The atmosphere, the formation of its measuring tube non-full tube; installed in the vertical flow from top to bottom, may appear to empty. 2, the environmental aspects of the main pipe stray current interference, space electromagnetic interference, large motor magnetic field interference. Pipeline stray current disturbances are generally measured with good individual earthing for satisfactory measurements. However, in the event of a strong stray current in the pipe (eg electrolysis workshop pipelines) it may not be able to overcome the need to take measures to minimize the flow sensor and pipe edge. Space electromagnetic interference - usually introduced via signal cables, is usually protected by a single or multiple shields, but it has not been overcome by the shield protection.
