Flow meter

This post was last edited by lv051302 on 2017-1-4 13:50. What are the reasons for the large fluctuations in the inlet flow rate of the rich gas compressor in the catalytic unit? (The raw materials are in good condition, and the reaction and distillation proceed smoothly as well.)
Could the operating conditions be described in more detail? Also, if there are trend charts, it will be easier for everyone to analyze them
A float? Not adding damping might……
By large fluctuations in traffic, does the poster mean fluctuations that occur all the time, or only in recent times or over a certain period? Amplitude of fluctuation? Explain these in detail, and the operating conditions should also be described in detail (for example, what is the type of flow meter, its diameter, and its flow range?) Compressor type? Medium? Distance between the flow meter and the compressor? Wait, etc.), so that an accurate analysis can be made.
What kind of flow meter is it? What is the medium? What are the operating conditions?
It’s too abstract; I don’t know where to start
Orifice plate flow meter, rich gas from the top of the distillation tower; inlet pressure not exceeding 0.2 Mpa, temperature around 35 degrees Celsius
Does the flow rate under actual operating conditions fluctuate on its own? Is there pressure measurement? Are there any fluctuations in pressure? Are all the pressure guide tubes unobstructed? Or is there any leakage? The damping time of the differential pressure transmitter is increased.
