Answer / sam

Capillary level transmitters are the best for just about any
application but they are very expensive compare to a normal
DP Cell with tubing.
The problem with these capillary transmitter installations
are that a lot of installations and designs are done without
flushing rings and equalization tubing and valves. This then
have to be installed afterwords since they are needed during
calibration once you start working on vessels with a process
pressure of 10bar and up. Without these the calibration will
become more inaccurate the higher your vessel process
pressure is. Be aware we still have static alignment
problems even in this day and age of smart technology.
Unless you do a process zero before your calibration you are
going to pick up problems and the only way to do a process
zero is if these flushing rings and tubing is installed from
the HP to the LP tap off points.
Good Luck
