Issue with liquid level gauge in inter-stage liquid separation tank of new hydrogen compressor
Thread Content
The level gauge (of the float type) always shows full scale even though there is no liquid in the liquid being discharged – how to deal with this?
What kind of level gauge? Only by knowing the specific model can the problem be resolved
The float inside is stuck there; contact the maintenance staff to handle it
We left the separator drain valve closed, there was frost on the outside of the pipeline, but the operations were not in accordance with the specifications.
Check whether the signal for remote transmission of the instrument is connected incorrectly, or whether the current signal value is incorrect； Is the float of the on-site instrument stuck? ； Re-calibrating it should do the trick.
Well, it’s more likely that there’s an issue with the card...
What medium are you using? Generally, only the inter-stage liquid removal tanks in the last two stages contain liquid. What was said above is correct – you need to have the instrumentation team handle it. You’re not an instrumentation specialist, are you? You can just calibrate it by referring to the glass panels on site
Based on an approximate estimation of the medium density, it’s sufficient if the liquid level is roughly the same as the actual value; it’s also okay if the observations don’t fluctuate in line with the actual values
Full scale displayed, no liquid in the drain------false level
