Some of the most crucial pieces of equipment aboard your tanker barge are cargo-gauging tools.  These monitor the level of cargo, ensuring that it’s safely contained.  Equipment which isn’t doing its job exposes you to the potential for environmental hazard.

Your tanker barge needs the most accurate cargo-gauging/barge-gauging equipment and protocols possible, to protect both your company and the environment from erroneous readings that can put you and the waters you ply at risk.  ERL is continually engaging in development and evolutionary innovation to ensure our products meet the challenge.
