1.1 Product Description
The AccuLoad provides accurate, reliable control and measurement of liquid petroleum blending and
transfer operations. While primarily intended for use in refined petroleum distribution terminals, it can be
easily configured for a wide variety of liquid transfer applications.
Operators can select an amount of product to transfer and the AccuLoad monitors and controls the
configured pumps, valves, and additive injectors to safely and efficiently transfer the precise recipe and
amount. During the transfer, all processing parameters are monitored to provide operators with an
accurate amount of each component of the recipe delivered.
In addition to real-time control of the loading process, the AccuLoad also calculates averages and live
quantities of all products and additives delivered. This information is stored in a runtime database that can
be monitored by a supervisory host system. Whenever a transaction is completed, the AccuLoad stores a
detailed record in an internal transaction log for subsequent retrieval or printing.
