The on-site magnetostrictive level gauge keeps shutting down and needing to be restarted
Thread Content
The material in question is ethylene oxide; this issue has occurred twice this year, with power outages and restarts taking place, and the indicator showed \"NO FLOAT\". Since this instrument is connected to the SIS system, it causes interlocks to activate in the middle of the night, which puts everyone on edge. Moreover, whenever a fault occurs, it’s necessary to transfer the liquid to another container. Do magnetostrictive level gauges often experience similar problems? Has anyone encountered such cases?
A power restart of a magnetostrictive level gauge along with the display of NO FLOAT usually indicates an abnormal float or a system fault. The material properties of ethylene oxide can affect the proper operation of equipment; for example, viscosity or corrosivity may influence the movement of floats. It is recommended to check whether the float is stuck or damaged, whether the power supply is stable, and whether all wire connections are secure. If the problem occurs frequently, consider using a gauge model better suited for harsh environments or increasing the frequency of maintenance. At the same time, you can consult the manufacturer or professional technicians for further diagnosis and problem resolution. .
Float jamming or leakage: The float may get stuck in a certain position due to impurities or deposits in the ethylene oxide, or the float itself may leak, preventing it from accurately reflecting changes in liquid level. When the level gauge detects an abnormal float, it may display “NO FLOAT”. Incorrect selection of float material: If the material of the float is not suitable for an environment with ethylene oxide, it may fail to function properly due to issues such as corrosion or expansion.
