Funny vessel design with level gauge!
Funny vessel design with level gauge!
(OP)
This sounds funny to me but is there any such thing where the level gauge is connected between bottom head (top of bottom) to the shell. In fact what sounds funnier to me is that the bottom nozzle also serve as an outlet connection. Have a look at this picture:
Is there any vessel design like this? The reason the level gauge is at the bottom is that the requirement by client is to make sure the vessel is fully empty and they dont want a deadstock left inside the tank, it means complete drain and is indicated by the level gauge.

If this is a drain then I can see why they would want / need this so that the lower part of the level guage is not always full to the level of the bottom of the tank or just above.
It is not usual to connect the bottom part to a normally flowing nozzle as this distorts the level reading, but as a drain to drain off the level guage and then isolate it again so that any liquid in the tank is measured seems Ok to me.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I questioned my process team, as this design was proposed by the process team. However my proposed design was to connect the level gauge between the nozzle as normal vessel did because whatever is left inside the tank will be drained out completely so I dont think it should be monitored. Again that's just my opinion.
RE: Funny vessel design with level gauge!
From your explanation I understand that an instrument connection shall not be interfere with a process connection, correct?
