Before Installing Your Equipment:
1. It is essential to install an effective earth ground. In some
areas the soil may need to be treated to obtain the required
conductivity. See section 2 - Installation.
2. SolarFlow Plus should be insulated from any existing
cathodic protection system, e.g., an insulating flange kit at
each end of the meter tube. See section 2 - Installation.
3. Select a site so that the solar panel receives direct
(unshaded) exposure from the sun from 9:00 A.M. to
4:00 P.M. See section 2 - Installation.
IMPORTANT SOLARFLOW
PLUS OPERATIONS NOTICE
A MINOR DESIGN FLAW HAS BEEN DISCOVERED IN AN
INTEGRATED CIRCUIT, WHICH IS SUPPLIED TO DANIEL INDUSTRIES
BY A THIRD PARTY MANUFACTURER. ALTHOUGH THIS CHIP IS
CURRENTLY USED IN VARIOUS DANIEL INDUSTRIES SOLARFLOW
PLUS UNITS, SOLARFLOW USERS ARE ADVISED THAT THIS
CONDITION DOES NOT ADVERSELY COMPROMISE THE OPERATION
OF THE UNIT. NO DATA WILL BE LOST AND NO MEASUREMENT
ERRORS WILL OCCUR. HOWEVER, IT IS POSSIBLE UNDER CERTAIN
CONDITIONS THAT THE DATE STAMP ON INDIVIDUAL DATA LOGS
MAY BE IN ERROR.
THE DANIEL INDUSTRIES PROGRAMMING STAFF IS WORKING TO
MODIFY THE SOLARFLOW SOFTWARE TO CORRECT THIS
SITUATION, BUT UNTIL THIS WORK IS COMPLETED, SOLARFLOW
USERS ARE ASKED TO MANUALLY SET THE REAL TIME CLOCKS IN
THEIR UNITS BETWEEN JANUARY 1 AND FEBRUARY 28 OF EACH
YEAR. INSTRUCTIONS FOR SETTING THE REAL TIME CLOCK ARE
FOUND IN THE SOLARFLOW PLUS SYSTEM REFERENCE MANUAL.

MODEL 2480 APPLICATION MANUAL
The Application Manual is specific to the application installed in the SolarFlow Plus whereas the
System Reference Manual is general in nature. Throughout the Application Manual the user will
be directed to sections in the System Reference Manual if more detailed information is desired.
The Application Manual lists all of the inputs and outputs for the application along with
termination points. In addition the Application Manual will list all of the default parameters
within the SolarFlow Plus so that the user may modify them, if required, to match the installation
requirements.
BEFORE INSTALLING YOUR EQUIPMENT:
1. It is essential to install an effective earth ground. In some areas the soil
may need to be treated to obtain the required conductivity. See section
2--Installation.
2. SolarFlow Plus should be insulated from any existing cathodic protection
system, e.g.,an insulating flange kit at each end of the meter tube. See
section 2--Installation.
3. Select a site so that the solar panel receives direct (unshaded) exposure
from the sun from 9:00 A.M. to 4:00 P.M. See section 2--Installation.

SOLARFLOW PLUS STARTUP
Refer to section 4 of the System Reference Manual for an outline of the start-up procedure.
Information relating to the specific menus for your application will be found in the Application
Manual.
1.2 SYSTEM DESCRIPTION
The Model 2480 SolarFlow Plus computer, together with associated equipment and software
programs, comprises a versatile measurement system that can calculate flow data from a variety
of input signals. The system can provide output information of various types in a variety of
forms. In addition, the system includes an elaborate audit trail capability as well as alarm and
data logging.
1.2.1 CALCULATIONS AND DATA INPUT
SolarFlow Plus calculations are based on inputs that define the properties and flow of the product
being measured. The computer accepts inputs from various primary elements such as temperature
and pressure transmitters and orifice and positive displacement meters. Input data can be in the
form of analog voltages, pulse inputs, operator-entered fixed values, or a combination of these.
The system also provides on-line correction of pressure, temperature and other varying
parameters. Either two- or three-point calibration is provided for all analog inputs with the
exception of differential pressure. Differential pressure inputs are calibrated using either a two-,
three-, or four-point calibration technique.
1.2.2 DATA AND EVENT LOGS
The SolarFlow Plus computer stores information in the form of data and event logs. Data logs
record both input and calculated data such as pressure, temperature, and flow rates. Data logs
are updated at user defined intervals. Event logs provide a record of significant events such as
changes to operator-entered data and the occurrence of alarm conditions. Event logs are
continuously updated by the SolarFlow Plus program.

OCT 1997
1.2.3 DATA OUTPUT
Model 2480 SolarFlow Plus provides output information in the form of digital signals, printed
reports, and local data display. Depending on the specific application, remote access to data can
be provided over telephone lines, radio links, and other media. Two primary methods of local
display are available: a liquid-crystal display (LCD) on the front panel of the SolarFlow Plus
enclosure, and the hand-held data terminal (HHDT). The LCD display scrolls through a
factory-defined report list that can include up to fifteen variables and also displays existing alarm
conditions. The HHDT provides operator access to a broad range of data through a menu system.
The operator can also collect data and event logs with the HHDT.
Figure 1-1 illustrates the maximum input/output (I/O) capability of the Model 2480 SolarFlow
Plus computer. The I/O options of the Model 2480 are dependent on the requirements of the
applications. Figure 1-2 illustrates I/O functions of the HHDT.

1.2.4 COMMUNICATIONS OPTIONS
The SolarFlow Plus design provides for several means of communication, including telephone
line, radio, cellular units, and satellite. Communications options include packages that provide
for digital communications to and from a SolarFlow Plus installation. The manual supplement
for a specific application provides a description of any special communications options provided
with the application.
Various software programs are available that provide specialized ways to access data from either
the SolarFlow Plus computer or the Hand Held Data Terminal. Brief descriptions of these
programs are provided in Appendix A. More detailed information is available from Daniel
Industries, Inc.
1.2.5 HARDWARE
SolarFlow Plus system hardware includes the Model 2480 flow computer, the required
transmitters, and a hand-held data terminal. A SolarFlow Plus system may also include modems
for data transmission over land lines, or an interface to customer supplied communications media.
Random-access memory (RAM) chips are provided with battery backup as standard.
The SolarFlow Plus computer operates on electrical power supplied by a 6-volt direct current
(VDC) battery pack. System design includes a solar panel array to recharge the battery pack.
The Model 2480 SolarFlow Plus system is designed as intrinsically safe for Class I, Division 1,
Group D environments.
