Have to agree with Naman that this is not the best way to do
it and there are other devices that will work better if the
current instillation can be modified to accommodate a
different type of instrument like a capillary type of DP Tx
or a level troll.
According to question, the DPT is already in place and needs
to be used so above is the way to do it, and yes it is
possible to do since I have done it myself on a d-aerator
column under constant 0,98Bar vacuum and a span of only
300mm. My situation was the same in that I could not just
modify the installation and had to work with what was
installed.
Keep in mind that once the wet leg is filled the vacuum is
pulling against a closed end. Test this the next time you
drink a Coke out of a can . Suck the straw full and close
the end with your finger and try and suck the Coke
out.(please use a metal tube and not a plastic straw, LOL)
Good luck
