The differential pressure level gauge shows fluctuations

2012-07-15View Original

Thread Content

The differential pressure level gauge used to monitor the liquid oxygen level in the distillation tower of the air separation unit has an EJA transmitter; after shutdown for maintenance, the level reading shows regular fluctuations. What could be the reason? Seeking advice from experts.

If it’s irregular, investigate the cause; if it’s regular, use filtering to eliminate interference~~~~~~~~~~~~~~~~~~~~~~~~

Check it against the on-site level gauge; if it matches, then it’s basically a matter of process operation
