1.0 INTRODUCTION

1.1 SCOPE OF THIS MANUAL

A SolarFlow Plus unit delivered from the factory is fitted with a set of erasable, programmable,

read-only memories (EPROMs) configured for the application or applications for which the

SolarFlow Plus is intended. The Hand Held Data Terminal (HHDT) provided with a SolarFlow

Plus unit is compatible with the same application or applications.

Basic reference information on the Model 2470 SolarFlow Plus system is provided in the System

Reference Manual (Daniel part number 3-9000-451). The System Reference Manual includes

sections on system hardware, software, installation, and operating procedures for both the

SolarFlow Plus computer and the HHDT.

Information on each application of the Model 2470 SolarFlow Plus is provided in a separate

application manual. The application manual also provides references to the System Reference

Manual whenever more detailed information is available in the reference manual. The application

manual together with the System Reference manual, provides a complete information package

for a specific installation of the Model 2470 SolarFlow Plus system.

This application manual provides specific information on a Model 2470 SolarFlow Plus unit and

the associated HHDT configured for the ENRON dual-meter AGA-3 application. Because an

individual configuration of a SolarFlow Plus unit may differ in some respects from the basic

system, information provided by the basic reference manual and this application manual may also

differ. When differences are noted, the information contained in the application manual takes

precedence.

1.3 INSTALLATION CONFIGURATION FOR THE ENRON DUAL METER RUN

AGA-3 APPLICATION WITH ONE DP TRANSMITTER PER METER TUBE

The SolarFlow Plus ENRON dual-meter run AGA-3 application is designed for installations with

two orifice-meter tubes. The application has:

- One differential pressure (DP) transmitter per tube

- One static pressure transmitter per tube

- A common temperature transmitter

- A common specific gravity input

Figure 1 shows the installation configuration for the transmitters in the ENRON dual-meter

AGA-3 application.

2.0 ENRON DUAL AGA-3 (AGA-3 DUAL) CALCULATION MODULE

This manual supports a SolarFlow Plus computer configured to calculate orifice-meter

measurements in accordance with the American Gas Association (AGA) Gas Measurement

Committee Report No.3 (AGA-3), Orifice Metering of Natural Gas, (ANSI/API 2530 Second

Edition, September 1985). Supercompressibility is calculated in accordance with AGA Standard

NX-19 - Manual for the Determination of Supercompressibility Factors for Natural Gas.

2.1 FLOW RATE

In general, the equation for calculating flow rate is:

Where:

= corrected flow rate in thousands of standard cubic feet per hour (MCF/HR)

= orifice flow constant calculated using the equation in 2.2

= differential pressure in inches of water

= static pressure in pounds per square inch, absolute (PSIA)

____________________________________________________ MODELMODEL 24702470 SOLARFLOWSOLARFLOW PLUSPLUS ENRONENRON AGA-3AGA-3 DUALDUAL

MAYMAY 19971997

2.2 ORIFICE FLOW CONSTANT (C

)

The equation for calculating the orifice flow constant (C

) is:

Where:

= basic orifice factor

= specific gravity factor

= supercompressibility factor

= flowing temperature factor

= result of multiplying: F

,Y,F

Where:

= pressure base factor

= temperature base factor

= Reynolds number factor

Y = expansion factor

= orifice thermal expansion factor

NOTE:NOTE: F

calculations are limited to adjusted pressures of 0 to 2000

pounds per square inch (PSI) and adjusted temperatures of -40 to

240 degrees Fahrenheit (

F).

The calculation methods of Channels 59, 63, 70, and 74 have been modified especially for

ENRON. They represent the average extension factors for the last hour or last day over the

flowing time period. The Extension Factor is defined as the square root of the product of

differential pressure and static pressure, i.e.

2.3 CALCULATION CYCLES

During normal SolarFlow Plus operation, calculations are performed continuously. Each

complete set of calculations is based on a calculation cycle. The time required to complete a

calculation cycle depends on processor speed and the extent of data communication required by

the application calculation module.

The SolarFlow Plus computer calculates the critical part of the flow rate calculation, extension

factor, ( h

)

, every half second. The computer calculates the factors included in the flow

constant (C

), at an interval defined by the application program, typically every 15 to 25 seconds.

The factors in C

that are dependent upon sampled input values use the average of the 0.5-second

samples in each calculation.

For example, if an application takes 20 seconds to calculate a new C

value, a total of 40

extension factors are calculated during the C

calculation interval. In addition, 40 samples of

each analog input are obtained and averaged during the same period of time. SolarFlow Plus

sums up and averages the individual extension factors then multiplies the result by the latest

calculated value of C

to produce an updated value for flow rate.

At the end of each flow rate calculation cycle, SolarFlow Plus updates channel values that are

dependent on the calculated value of flow rate, such as flow rate, and total volume.
