3.1.4 Additive Injection
Additive injection is a process in which small amounts of additives are
added to the final product. The additive product is injected in pace with
the product flow. That is, the additive injection occurs after an interval of
configured pacing volume until the end of the batch. The recipe
configured on the MSC-L controls the rate of additive being injected into
the product stream.
When the MSC-L determines that an additive cycle is required, it opens
the solenoid control valve and injects a small quantity of additive into
the product stream. When the amount of additive is reached for that
cycle, the solenoid valve is closed and the instrument waits until the
next additive cycle is required. The additive injection cycle repeats in
this manner, which keeps the additive synchronised with the product
flow.
MSC-L also supports additive injection by interfacing with External
additive controller. For more details, see chapter 5.11 "Interfacing With
External Additive Controller".
NOTE: The MSC-L assumes that the additive piping is done
in such a way that additives comes in upstream
(before) the custody transfer flow meter.
When the additive piping is done in such a way that
additives comes in downstream (after) the custody
transfer flow meter the additive is not a part of the
finalized product volume but the individual additive
volumes are measured and are part of the trans
-
action record and therefore available when viewing
transactions or for printing additive reports by the
Fusion4 Portal.
3.1.5 Loading Principle
The loading arm of the MSC-L supports the control of the following as
described in the following figure.
Maximum 7 product streams
Maximum 12 additive streams (inclusive of internal additive streams
and upto 6 external additive streams)
