The AccuLoad III-N4 provides a unique solution for controlling<br />
the batch loading of products through multiple<br />
load arms. Two loading arms and three meters can be<br />
controlled with the AccuLoad III-N4. The unit is ideal for<br />
truck, barge, or rail car loading at loading racks, bulk<br />
plants, shipping docks, processing installations, and<br />
tank farms where straight products, as well as blended<br />
products, must be accurately loaded.<br />
Standard Features<br />
AccuLoad ® III-N4<br />
Specifications<br />
The following descriptions of straight product, sequentially-blended<br />
product, ratio-blended product, and side<br />
stream blended product loading are written as if all<br />
loading arms are programmed for that type of loading.<br />
In reality, all the following combinations of loading arm<br />
configurations are available in the AccuLoad III-N4.<br />
Straight Product<br />
The AccuLoad III-N4 is designed to handle two arms of<br />
straight products. Both arms can be loaded simultaneously.<br />
Sequential Blending<br />
The AccuLoad III-N4 is designed to sequentially control<br />
the loading of up to six petroleum or chemical products<br />
through each of two loading arms. Both of the loading<br />
arms can be loaded simultaneously.<br />
Ratio Blending<br />
The AccuLoad III-N4 is designed to control the blending<br />
of up to three petroleum products through a single<br />
The Most Trusted Name In <strong>Measurement</strong>
loading arm. All products flow through a metering<br />
system, are co-mingled downstream of the metering<br />
system, and flow through a single loading arm into<br />
a transport or into storage. Since both of the loading<br />
arms are programmable, the unit could be programmed<br />
for two load arms, one of which could be programmed<br />
as a two-product blender and the other as a straight<br />
product arm.<br />
Side Stream Blending<br />
The AccuLoad III-N4 is designed to control the blending<br />
of a minor product and a major product. The minor<br />
product is metered and controlled by a valve and the<br />
main product is free flowing. A second meter and control<br />
valve is located down stream of the blending point<br />
and measures/controls the flow of the blended product.<br />
The second arm could be programmed as a straight<br />
product arm.<br />
Wild Stream Blending<br />
The AccuLoad also supports Wild Stream Blending,<br />
which allows for continuous (no preset entered) ratio<br />
blending of products. One of the products can be uncontrolled<br />
(wild stream). This option is also available with the<br />
hybrid arm configuration. Wild Stream Blending supports<br />
“on the fly” blend percent changes and also for changing<br />
meters to accommodate varying flow rates.<br />
Temperature Compensation<br />
The temperature compensation option provides the<br />
customer with the capability of compensating for the<br />
variance in temperature from a reference temperature.<br />
This option is used with an RTD input or a temperature<br />
transducer and, excluding the accuracy of the fluid temperature<br />
measurement, will exactly match the proper<br />
volume correction factor of ASTM-D-1250-04 and API<br />
MPMS CH 11.1 - 2004 over the fluid temperature range<br />
of -40°F to 572°F (-40°C to 300°C). The following API<br />
tables can be programmed in the AccuLoad III: 5A,<br />
5B, 5D, 6, 6A, 6B, 6C, 6D, 23, 23A, 23B, 23D, 23E, 24,<br />
24A, 24B, 24D, 24E, 53, 53A, 53B, 53D, 54, 54A, 54B,<br />
54C, 54D, 59A, 59B, 59D, 60A, 60B, 60D, BR1A, BR1P,<br />
and BR2P.<br />
Pressure Compensation<br />
The pressure compensation option provides the customer<br />
with the capability of compensating the volume<br />
of product delivered at varying pressures per API Tables<br />
11.2.1 and 11.2.2, using a 4-20 mA pressure transducer<br />
input per preset position. This option also contains realtime<br />
control functions for maintaining system pressures<br />
at the meter to a minimally-acceptable, user-definable<br />
level (pressure transducer not included). This option<br />
is particularly useful for light products, such as LPG,<br />
where the compressibility factor varies a great deal with<br />
different pressures.<br />
Density Correction<br />
The density correction option provides the customer<br />
with the capability of correcting the volume of product<br />
delivered at varying densities. This can be either a frequency<br />
input or a 4-20 mA input.<br />
Metered Injectors, Piston Injectors and Smart<br />
Additives<br />
The AccuLoad III has been designed to provide maximum<br />
flexibility when it comes to additive control. The unit<br />
is capable of handling metered injectors, piston injectors<br />
and smart additives simultaneously.<br />
The AccuLoad is capable of controlling four additive<br />
injector metered systems. (See Hardware Options for<br />
additional injector systems.) The AccuLoad controls<br />
the additive solenoids to precisely inject the additive into<br />
the main product. It monitors the pulses of the additive<br />
meter and controls the amount of the additive, based<br />
on the incoming pulses from the additive meter and the<br />
main product meter.<br />
Additive monitoring and smart additives provide the<br />
capability for the AccuLoad to monitor the feedback<br />
from the piston injectors of the additive products. The<br />
AccuLoad monitors the injector feedback switches for<br />
a change of state and counts the errors and alarms if<br />
no change is detected within the cycle or a period of<br />
time, depending on how the unit is programmed. The<br />
AccuLoad will totalize the additive volume based on<br />
confirmation signals and a programmable volume per<br />
cycle. The totalized volume will print on the emulated<br />
load ticket printed on the shared printer output.<br />
For Smart additives, the firmware has also been designed<br />
with a Master/Slave type of communications,<br />
with the AccuLoad being the master and the Additive<br />
Injector System being the slave. The AccuLoad constantly<br />
interrogates the Additive Injector System for<br />
a change in status. The AccuLoad can be operated<br />
with communications control over the Smart Additive<br />
Injector System or with communication/pulse control.<br />
When the AccuLoad has communication control over the<br />
Additive System, it will constantly monitor the Additive<br />
System for its status, poll the additive totals, and signal<br />
the system when to inject the additive -- all through the<br />
communications line.<br />
The AccuLoad communications package has also been<br />
designed with a pass-through communications mode. In<br />
this mode of operation the supervisory computer can talk<br />
to the Additive Injector System through the communication<br />
lines that have been run to the AccuLoad and from<br />
the AccuLoad to the Additive Injector System(s).<br />
Dual Pulse Security<br />
This option provides continuous monitoring, error indication<br />
alarm, and correction of the pulse transmission for<br />
each preset position per API Petroleum <strong>Measurement</strong><br />
Standard, Chapter 5.5, Level A, and Institute of Petroleum<br />
Standard, IP 252/76, Part XIII, Section 1, Level A<br />
(PPS High-Security Pulse Transmitter is not included).<br />
The PPS High-Security Transmitter provides four signals:<br />
“A,” “A inverted,” “B,” and “B inverted.” The “A” and<br />
“B” signals are 90 electrical degrees out-of-phase and<br />
used for dual-pulse security. The “A” and “A inverted,”<br />
and “B” and “B inverted” signals are 180 electrical degrees<br />
out-of-phase and are used for transmitter power<br />
sensing. If power sensing is not required, only “A” and<br />
“B” are used for dual-pulse security.<br />

Automated Proving Mode<br />
The AccuLoad III firmware provides an automated proving<br />
mode of operation. When the automated proving<br />
mode is activated the AccuLoad will calculate the meter<br />
factor for a proving run based on information that is<br />
obtained during the prove. The operator can select the<br />
flow rate and meter factor that is being proved through<br />
the keypad of the AccuLoad. After the prove is complete<br />
the operator enters the prover volume and prover<br />
temperature and the AccuLoad will calculate the new<br />
meter factor. The operator has the choice of downloading<br />
it to the program or ignoring it. The AccuLoad also<br />
has the capability of providing an average meter factor<br />
over a maximum of ten proves. This feature allows the<br />
operator to prove the meter on all four products, and<br />
four meter factors and associated flow rates for each<br />
product without having to enter the program mode for<br />
each product and meter factor.<br />
Boolean and Algebraic Processing<br />
The AccuLoad III provides the customer the flexibility to<br />
set-up inputs and outputs for tasks that are not standard<br />
in the unit. Through Boolean processing, relays can be<br />
turned on and off through equations and events set up<br />
by the customer. For example, a relay is required to<br />
close at the first trip point of the load. This can be set up<br />
using Boolean processing and does not require special<br />
software from Smith.<br />
Algebraic processing is also a feature that the customer<br />
can use to do simple mathematical calculations that are<br />
not in the unit. These calculations can then be used on<br />
the configurable reports for the current batch being run<br />
by the unit.<br />
Hardware Options<br />
AccuLoad Interface Control Board<br />
The AccuLoad Remote Mounted Interface Control Board<br />
provides additional flexibility to the AccuLoad's standard<br />
features. The optional AICB Board provides either ten<br />
additional metered additive injector systems or twenty<br />
additional programmable outputs per board set. With<br />
the optional AICB Board, the AccuLoad III with firmware<br />
has the capability of handling up to twelve metered<br />
injectors, twelve meter inputs, twelve solenoid valve<br />
outputs, and twelve additive pump outputs. One of the<br />
four communication ports is required to communicate<br />
with the AICB Board.<br />
ComFlash Mass Storage Expansion Board<br />
The optional hardware module provides additional nonvolatile<br />
memory to store transaction data. The module<br />
come with a 512 M SD card that has the capability of<br />
storing thousands of additional transactions. The module<br />
is only available on COM 4 and uses RS232 communications.<br />
The A3X also provides alarms for the expansion<br />
board to ensure proper operation. The Smith Meter ®<br />
Proximity Card Reader can also operate on COM 4 in<br />
conjunction with the ComFlash board.<br />
Card Reader<br />
The Smith Meter ® Card Reader can be added to the face<br />
of the AccuLoad III-N4. This option provides an integrally<br />
mounted RF-based proximity reader to the AccuLoad<br />
III. It is capable of interpreting multiple card formats<br />
and transmitting card data either to the AccuLoad III or<br />
directly to an automation system.<br />
