In any liquid-based manufacturing unit, such as a refinery or chemical facility, tanks are used to store feed stocks, intermediate and final products. It is important to know tank contents, in terms of both quantity and quality, allowing business and operational decisions to be made in a timely manner, thus minimizing bottom-line impact. While real-time tank inventory can be obtained online with an automatic tank-gauging system, it is not easy to get real-time information about tank qualities that can affect plant operational decisions.
