2. Common faults during the operation of split type _600x400.jpg)
Common faults and causes during the operation of split type electromagnetic flowmeter. Split type electromagnetic flowmeter may encounter various faults during operation, which are usually caused by internal connection layer problems, lightning strikes, and changes in environmental conditions.
. The following is a detailed analysis of these common faults and their causes:1. Internal connection layer fault phenomenon: When measuring fluids containing suspended solids or internal dirty particles, the internal connection of the split electromagnetic flowmeter is prone to failure. This failure may result in measurement errors or malfunction of the instrument. Reason analysis: Conductivity adhesion layer: If the conductivity and liquid conductivity adhesion layer are tightly packed, although the instrument can output normal signals, it will change the flow field and form an implicit fault of measurement error. High conductivity adhesion layer: The high conductivity adhesion layer may cause a short circuit of electromotive force between the electrodes, making the instrument unable to function properly. Insulation layer connection: Insulation layer connection may cause insulation on the electrode surface and disconnect the circuit, which can also render the instrument inoperable.
2. Lightning strike fault phenomenon: Lightning strikes may cause damage to the internal circuit of the split electromagnetic flowmeter, making the instrument unable to work properly.
. Reason analysis: Lightning strike method: There are three main ways in which lightning strikes damage instruments: through power lines, excitation signal lines between sensors and converters, and streamline lines. Hig
