Blockage of the pressure lead pipe caused failure of both the on-site and remote level gauges
Thread Content
The interior of the acid gas knock-out drum in the venting pipeline network contains sludge and crystalline particles. This frequently causes IO failures in both glass plate level gauges and remote level transmitters, making it impossible to monitor the actual liquid level. Under normal operating conditions, is there any effective way to clean the interior of this drum?
1) Optional first-stage bore connection, larger channel size； 2) Add low-point sewage outlets for regular discharge ； 3) When the temperature is low, trace heating and insulation measures can be considered ； 4) Install a filter screen at the liquid level port ； There’s always a way to solve it. For in-depth discussions, I, Chuan You, can provide answers for you.
It is advisable to consider replacing it with a double-flange differential pressure level gauge equipped with capillaries
There is a problem with the selection itself: whether the sludge will stick or not. If it doesn’t stick, then a differential diaphragm type should be chosen; however, it’s difficult to ensure that no liquid gets into the level gauge, and this increases the cost as well
