ABSTRACT:
A method and system is provided for removing hazardous liquid from a wet line of a cargo tanker truck. The system includes a sight glass module positioned at the outboard end of the wet line. The sight glass module includes a vent, a drain, and an optical sensor. When the optical sensor senses liquid in the module, a control system operates to pump the liquid from the drain into the cargo tank.
