Online maintenance of plug-in electromagnetic flowmeter:
During the commissioning of plug-in electromagnetic flowmeter, the environmental conditions are still good (for example, there is no interference source) and the flowmeter works normally. At this time, it is often easy to ignore the installation conditions ( For example, the grounding is not very good). In this case, once the environmental conditions change and new sources of interference appear during operation (such as electric welding on the pipeline near the flow meter, large transformers installed nearby, etc.), it will interfere with the normal operation of the meter and the output of the flow meter. The signal will fluctuate.
Although the plug-in electromagnetic flowmeter is simple to operate and requires less maintenance, long-term use will still cause the electricity to become dirty or worn. Therefore, to ensure accurate measurement, it is very necessary to conduct regular maintenance of the plug-in electromagnetic flowmeter. For plug-in electromagnetic flowmeters, the system must be shut down for each maintenance and the liquid in the pipeline must be drained before disassembly. If a malfunction occurs during abnormal maintenance, the disassembly and assembly of the plug-in electromagnetic flowmeter will have a great impact on continuous production efficiency. Therefore, an isolation ball valve can be installed on the mounting base to achieve online plugging and unplugging without the system being shut down to ensure continuous and stable operation of the system.
