A mass flow meter operating by the Coriolis principle, with a measuring tube through which flows a medium, at least one exciter associated with and exciting the measuring tube, and at least one sensor associated with the measuring tube for capturing the Coriolis forces andor the Coriolis-force-induced oscillations. When the cell voltage is decreased, the apparatus of the present invention recovers the cell voltage by making the negative pressure large to accelerate the discharge of the produced water with minimized power consumption. Upon determining the data field size, an RLC PDU is generated such that it matches the requested data from the E-TFC selection. When the firmware receives input from a graphical user interface that includes at least a first FRU selected for virtual removal from the computer system, the firmware adds the RID number of the selected FRU to the memory directory and recollects VPD.
