5.8 Unloading Application Overview
The Fusion4 MSC-L supports unloading (offloading) application.The
unloading assemblies cover a range of requirements, starting with
simple single-unit, standalone unloading skids for the emptying of road
tankers and transferring product from vehicle to site storage.
The MSC-L have a configuration parameter to configure the device for
unloading with preset or unloading without preset.
These systems can be fully automated with dual redundancy,
integrating multiple functions into the offloading process such as de-
aeration, denaturing, additivation or blending. Multiple metering
technologies can be utilized in these systems including positive
displacement and Coriolis for custody transfer, with both local and
remote data reconciliation. Ethanol and biodiesel offloading can be
facilitated from both road tanker and rail car, as can LPG.
During unloading operation, the MSC-L controls the centrifugal pump,
flow meter, direct control valve, high flow switch, low flow switch, stop
flow switch, and dry run switch. Refer to the figure 5-22 for unloading
product flow.
NOTE: when a centrifugal pump is used the flow rate may be
adjusted by using a digital control valve. But, when a
positive displacement valve is used the flow rate may
not be controlled by a DCV. However, by configuring
a two stage valve, the two provided control signal
may be used by device external to the MSC-L to
derive the proper frequency to control the pump.
