Abstract
A method for locking out load cells includes dispensing a fluid into a collapsible bag that is supported within a support housing, the support housing resting on a plurality of load cells that sense the weight of the fluid; manipulating a plurality of lockouts located adjacent to corresponding load cells from a first position to a second position so that the lockouts remove at least a portion of the weight of the fluid from the plurality of load cells; moving the support housing containing the collapsible bag with the fluid therein to a new location; and further manipulating the plurality of lockouts from the second position back to the first position so that the plurality of load cells again sense the full weight of the fluid within the collapsible bag.
