Applications
Standard Features
Applications include batch loading of alcohols, gasolines,
antifreeze, lube oils, fuel oils, solvents, fertilizers, LPG, LNG
and chemicals. The system is ideal for truck, barge, or rail
car loading at loading racks, bulk plants, shipping docks,
processing installations and tank farms where straight
products, as well as blended products, must be loaded.
The AccuLoad loading arm functions are individually programmable providing flexibility for how each arm can be
configured. The following charts and descriptions define
the types of loading including straight product and various
styles of blending. The AccuLoad III-S hardware has three
product meters that can be used among two load arms
while the AccuLoad III-Q hardware has six product meters
available to be used among six load arms.

Note: Two product ratio can be either two product ratio or two product side stream blending.
Straight Product
The AccuLoad III is designed to handle loading of straight
products. All products can be loaded simultaneously.
Sequential Blending
The AccuLoad III is designed to sequentially control the
loading of up to six petroleum or chemical products
through each loading arm. All loading arms can be loaded
simultaneously.
Ratio Blending
The AccuLoad III-Q is designed to control the blending of
up to six petroleum products and the AccuLoad III-S up to
three products through a single loading arm. All products
flow through a metering system, are co-mingled downstream of the metering system, and flow through a single
loading arm into a transport or into storage.

Bulletin SS06036 Issue/Rev. 1.0 (8/14)
Side Stream Blending
The AccuLoad III is designed to control the blending of a
minor product and a major product. The minor product is
metered and controlled by a valve and the main product is
free flowing. A second meter and control valve is located
down stream of the blending point and measures/controls
the flow of the blended product.
Hybrid Blending
The AccuLoad III supports hybrid blending which is defined
as a combination of sequential blending and ratio blending. A typical hybrid blending arm configuration may be
three sequential products and one or two ratio products.
The sequential products flow one at a time and in most
cases one of the ratio products would flow simultaneously
with each of the sequential prducts. The ratio products(s)
can be plumbed either upstream or down stream of the
sequential product meter. On a hybrid arm there must be
at least one sequential product configured.
Wild Stream Blending
The AccuLoad also supports Wild Stream Blending,
which allows for continuous (no preset entered) ratio
blending of products. One of the products can be
uncontrolled (wild stream). This option is available with
the hybrid arm configuration. Wild Stream Blending
supports “on the fly” blend percent changes and also for
changing meters to accommodate varying flow rates.
Temperature Compensation
The temperature compensation option provides the
customer with the capability of compensating for the
variance in temperature from a reference temperature.
This option is used with an RTD input or a temperature
transducer and, excluding the accuracy of the fluid
temperature measurement, will exactly match the proper
volume correction factor of ASTM-D-1250-04 and API
MPMS CH 11.1-2004 over the fluid temperature range of
-58°F to 302°F (-50°C to 150°C). The following API tables
can be programmed in the AccuLoad II: 5A, 5B, 5D, 6A,
6B, 6C, 6D, 23A, 23B, 23D, 24, 24A, 24B, 24D, 53A, 53B,
53D, 53E, 54, 54A, 54B, 54C, 54D, 54E, 59A, 59B, 59D,
59E, 60A, 60B, 60D, 60E, BR1A, BR1P, and BR2P.
Pressure Compensation
The pressure compensation option provides the customer
with the capability of compensating the volume of product delivered at varying pressures per API Tables 11.1,
11.2.1 and 11.2.2, using a 4-20 mA pressure transducer
input per preset position. This option also contains realtime control functions for maintaining system pressures
at the meter to a minimally-acceptable, user-definable
level (pressure transducer not included). This option is
particularly useful for light products, such as LPG, where
the compressibility factor varies a great deal with different
pressures.
Density Correction
The density correction option provides the customer
with the capability of correcting the volume of product
delivered at varying densities. This can be either a
frequency input or a 4-20 mA input.
Metered Injectors, Piston Injectors and
Smart Additives
The AccuLoad III has been designed to provide maximum
flexibility when it comes to additive control. The unit is
capable of handling metered injectors, piston injectors and
smart additives simultaneously.
Additive monitoring and smart additives provide the
capability for the AccuLoad to monitor the feedback from
the piston injectors of the additive products. The AccuLoad
monitors the injector feedback switches for a change of
state and counts the errors and alarms if no change is
detected within the cycle or a period of time, depending
on how the unit is programmed. The AccuLoad will totalize
the additive volume based on confirmation signals and a
programmable volume per cycle. The totalized volume will
print on the emulated load ticket printed on the shared
printer output.
For Smart additives, the firmware has also been designed
with a Master/Slave type of communications, with the
AccuLoad being the master and the Additive Injector
System being the slave. The AccuLoad constantly
interrogates the Additive Injector System for a change
in status. The AccuLoad can be operated with communications control over the Smart Additive Injector System or
with communication/pulse control. When the AccuLoad
has communication control over the Additive System, it
will constantly monitor the Additive System for its status,
poll the additive totals, and signal the system when to
inject the additive all through the communications line.
The AccuLoad communications package has also been
designed with a pass-through communications mode.
In this mode of operation the supervisory computer can
talk to the Additive Injector System through the communication lines that have been run to the AccuLoad and from
the AccuLoad to the Additive Injector System(s).
Dual Pulse Security
This option provides continuous monitoring, error indication alarm, and correction of the pulse transmission for
each preset position per API Petroleum Measurement
Standard, Chapter 5.5, Level A, and Institute of Petroleum
Standard, IP 252/76, Part XIII, Section 1, Level A (PPS HighSecurity Pulse Transmitter is not included). The PPS HighSecurity Transmitter provides four signals: “A,” “A
inverted,” “B,” and “B inverted.” The “A” and “B” signals
are 90 electrical degrees out-of-phase and used for dualpulse security. The “A” and “A inverted,” and “B” and “B
inverted” signals are 180 electrical degrees out-of-phase
and are used for transmitter power sensing. If power
sensing is not required, only “A” and “B” are used for
dual-pulse security.
The AccuLoad is capable of controlling four additive injector
metered systems. (See Hardware Options for additional
injector systems.) The AccuLoad controls the additive solenoids to precisely inject the additive into the main product.
It monitors the pulses of the additive meter and controls the
amount of the additive, based on the incoming pulses from
the additive meter and the main product meter.

Automated Proving Mode
The AccuLoad III firmware provides an automated proving
mode of operation. When the automated proving mode is
activated the AccuLoad will calculate the meter factor for a
proving run based on information that is obtained during
the prove. The operator can select the flow rate and
meter factor that is being proved through the keypad of
the AccuLoad. After the prove is complete the operator
enters the prover volume and prover temperature and
the AccuLoad will calculate the new meter factor and the
operator has the choice of downloading it to the program
or to ignore it. The AccuLoad also has the capability of
providing an average meter factor over a maximum of
six proves. This feature allows the operator to prove the
meter on all four products, and four meter factors and
associated flow rates for each product without having
to enter the program mode for each product and
meter factor.
Boolean and Algebraic Processing
The AccuLoad III provides the customer the flexibility to
set-up inputs and outputs for tasks that are not standard
in the unit. Through Boolean processing, relays can be
turned on and off through equations and events set-up
by the customer. For example, a relay is required to close
at the first trip point of the load. This can be set-up using
Boolean processing and does not require special software
from Smith Meter.
Algebraic processing is also an area that the customer
can use to do simple mathematical calculations that are
not in the unit. These calculations can then be used on
the configurable reports for the current batch being run
by the unit.
Unloading
When using Firmware Revision 10.01 and above, the
AccuLoad III allows a truck compartment to be unloaded
without entering a preset volume. Implementing this
feature requires that a load arm be identified as
“unloading”; up to six load arms can be so configured.
Hardware Options
AccuLoad Interface Control Board
The AccuLoad Interface Control Board provides additional
flexibility to the AccuLoad’s standard features. The
optional AICB Board provides either ten additional
metered additive injector systems or twenty additional
programmable outputs. With the optional AICB Board,
the AccuLoad III with firmware has the capability of
handling up to fourteen metered injectors, fourteen meter
inputs, fourteen solenoid valve outputs, and fourteen
additive pump outputs. Adding two AICB Boards provides
the capability of this unit to handle up to twenty-four
4
Bulletin SS06036 Issue/Rev. 1.0 (8/14)
additive injector systems (meters, additive pumps, and
solenoid valves) or an additional forty programmable AC
outputs. The optional AICB Board(s) are designed to either
be mounted in the AccuLoad III housing or in a standalone enclosure. One of the four communication ports is
required to communicate with the AICB Board.
ComFlash Mass Storage Expansion Board
This optional hardware module provides additional nonvolatile memory to store transaction data. The module
comes with a 512 M SD card that has the capability of
storing thousands of additional transactions. The module
is only available on COM 4 and uses RS232 communications. The A3X also provides alarms for the expansion
board to ensure proper operation. The Smith Meter
Proximity Card Reader can also operate on COM 4 in
conjunction with the ComFlash board.
Card Reader Interface
When using Firmware Revision 10.01 and above, the
AccuLoad III can obtain proximity card data through a
proprietary interface board. The AccuLoad can also pass
card data and status to a host computer. The card reader
interface is activated by choosing the card reader option
in the serial communications function program code. This
new interface offers the potential for enhanced functionality and security ranging from simple transaction-stamping
with driver card data to a mini automation system with
validation and authorization.
