A method for locking out load cells, the method comprising: dispensing a fluid into a collapsible bag or container or semi-rigid container 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 or container or semi-rigid container 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, container or semi-rigid container, wherein each load cell is disposed between a lower support and an upper support, the weight of the fluid being transferred through the upper support to each of the load cells; each lockout comprising: a receiver coupled with one of the lower support or the upper support, the receiver having an end surface with an opening formed thereon; and a stem coupled with the other of the lower support or the upper support, at least a portion of the stem being freely received within the opening of the receiver so that the stem can freely slide within the opening; characterized by a lockout nut threaded onto the stem such that rotation of the lockout nut in a first direction causes the lockout nut to rotate on the receiver and the lockout to be in the second position and rotation of the lockout nut in an opposing second direction causes the lockout to be in the first position. dispensing a fluid into a collapsible bag or container or semi-rigid container 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 or container or semi-rigid container 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, container or semi-rigid container, wherein each load cell is disposed between a lower support and an upper support, the weight of the fluid being transferred through the upper support to each of the load cells; each lockout comprising: a receiver coupled with one of the lower support or the upper support, the receiver having an end surface with an opening formed thereon; and a stem coupled with the other of the lower support or the upper support, at least a portion of the stem being freely received within the opening of the receiver so that the stem can freely slide within the opening; characterized by a lockout nut threaded onto the stem such that rotation of the lockout nut in a first direction causes the lockout nut to rotate on the receiver and the lockout to be in the second position and rotation of the lockout nut in an opposing second direction causes the lockout to be in the first position. a receiver coupled with one of the lower support or the upper support, the receiver having an end surface with an opening formed thereon; and a stem coupled with the other of the lower support or the upper support, at least a portion of the stem being freely received within the opening of the receiver so that the stem can freely slide within the opening; characterized by a lockout nut threaded onto the stem such that rotation of the lockout nut in a first direction causes the lockout nut to rotate on the receiver and the lockout to be in the second position and rotation of the lockout nut in an opposing second direction causes the lockout to be in the first position.
