Fluctuations in the flow rate of the lean methanol pump

The outlet flow rate of the lean methanol pump fluctuated momentarily (over 30 seconds) to several dozen cubic meters (the normal value being 300 cubic meters), before returning to its normal level quickly. No fluctuations in outlet pressure were detected during on-site inspections, nor were any current fluctuations observed in electrical checks. So what caused the flow rate fluctuations in the lean methanol pump? Have other sailors encountered similar situations? How did they resolve them? Seeking to share experiences.

The flow meter was calibrated online, and no issues were detected; it’s likely not a problem with the instrument

Could there be large fluctuations in the volume of gas carried?
