Regarding the drum level issue
Thread Content
There are two sets of level gauges for monitoring the liquid level in the drum of the catalytic external heat exchanger: one uses magnetic float technology and the other uses a double-flange design. These gauges are installed on both sides of the drum, and the differences in their readings are more than 20%. Each set comes with both remote and local reading capabilities. The process specifications state that the levels inside the drum should be consistent; a difference of over 20% is not acceptable according to these specifications. Need an explanation?
The liquid level difference is over 20. I analyze the reasons as follows: 1. The design of the feed inlet – the level displayed will be higher on the side that is closer to the corresponding level gauge. 2. The internal components within the steam drum prevent smooth flow of the medium inside, resulting in deviations in the liquid level. 3. An uneven pressure within the steam drum can also lead to inconsistent readings of the liquid level
1 First, confirm that there is nothing wrong with the instrument; clearly tell the process team that my instrument is fine and ask them to find the cause； 2 To find out exactly what causes it, go and look at the equipment drawings to examine its internal structure.
Your approach is incorrect. The fact that the remote transmission and local reading for each set correspond to each other only indicates that there are no issues with the signal transmission from those two level gauges; it does not tell us which set is being used and which one is not. Therefore, the proper approach is to determine which level reading is accurate, and to adjust the inaccurate one as soon as possible!
I wrote it wrong; it’s not \"prepare\" but \"accurate\"
