    Abstract - (Show below) - (Hide below)

    Describes the metrological and technical requirements for the pattern approval and verification of instruments used to determine the mass of liquid contained in a tank using methods which measure mass-related properties of the liquid while it is in a static state, e.g. the hydrostatic pressure of the liquid and gases in the tank.
