LEVEL CONTROL DEVICE FOR A SUMP TANK

摘要

The present invention relates to a level control device for a liquid in a sump and a method of controlling the level of liquid in a sump. The device is suitable for use with an on board system for scrubbing marine exhaust gases. A system (1) for controlling the level of liquid in a sump comprises a sump (2) and a conduit (5) connected to the sump at a first level (23). The conduit (5) defines a flow path for liquid flowing from the sump (2) and extends to a second level (24), which is at a higher level than the first level (23). The conduit (5) then extends from the second level (24) to a third level (25) which is at a lower level than the first level (23). As fluid flows down the conduit (5) from the second level (24) to the third level (25) it may be aerated.
