Bouncing Level Indicator
Bouncing Level Indicator
(OP)
We have several liquid nitrogen tanks equipped with Barton level indicators. One of the tanks is pressurized with nitrogen gas through a regulator and solenoid valve. When the solenoid is opened the level indicator starts bouncing 1-2 times per second. Bouncing stops after the solenoid closes. This same tank used to be pressurized with a pressure-build coil. I never saw the indicator bounce.
Seems like there is something related to heat leak, but I don't understand what is happening. Any insights?

If the rate of pressurization is the same between the PB coil and new method of pressurization, the above might not provide a satisfying answer.
