This document details the equipment to be used for closed, restricted and open manual level measurement, and gives procedures for manual level measurement of petroleum liquids in fixed-roof tanks, floating-roof tanks and vessel's cargo tanks, and for manually gauging the level of free water.

Measurement accuracy is essential for the sale, purchase and handling of petroleum products, and demands the use of standard equipment and procedures. It reduces the likelihood of disputes between buyer and seller and facilitates control of losses.
