    Image of Specification. Front orientation. ZoomedIn view. Contains Annotated, MultipleImages. Liquid-Level Tape Measures. Measures Liquid Removed from Tank.
    Liquid removed from tank tape measures have a rectangular plumb bob. To find the amount of liquid removed from a tank, lower the plumb bob until it makes contact with the liquid’s surface, then add the measurement from the plumb bob to the measurement from the blade. To determine the amount of liquid in the tank, subtract the liquid removed from tank measurement from the overall tank height.
