4 1 INTRODUCTION 1.1 Scope and Organization This document serves as the user manual for the MI-2667 Annubar Flow Calculation User Program (QER 05Q038), which is intended for use in a FloBoss 103. This manual describes how to download and configure this program (referred to as the Annubar Calculation program or the program throughout the rest of this manual). You access and configure this program using ROCLINK 800 Configuration Software (version 1.50 or greater) loaded on an IBM-compatible personal computer running Windows 98, ME, NT 4.0 (with Service Pack 6), 2000 (with Service Pack 2), or XP. The sections in this manual provide information in a sequence appropriate for first-time users. Once you become familiar with the procedures and the software running in a FloBoss 103, the manual becomes a reference tool. This manual has the following major sections: Section 1 Introduction Section 2 Installation Section 3 Configuration Section 4 Reference This manual assumes that you are familiar with the FloBoss unit and its configuration. For more information, refer to the FloBoss 103 Flow Manager Instruction Manual (Form A6114) or the ROCLINK 800 Configuration Software User Manual (Form A6121). 1.2 Product Overview The MI-2667 Annubar Flow Calculation user program enables a FloBoss 103 to calculate flow rates, integrate volumes, and store historical values determined using the Russian MI-2667 standard. The program provides flow calculations for gas, steam/water, and fluid applications in Metric units. It supports installations implementing either an Annubar Diamond II or an Annubar 485 T-shaped element type. This program provides a program-specific Annubar Calculation screen (see Figure 14) for entering additional program-specific parameters. The FloBoss 103 reads flow inputs (differential pressure, temperature, and static pressure) once every second. The program performs Annubar instantaneous flow rate calculation once every second. You configure the program using the standard Meter Setup screen and the Annubar Calculation screen. The program itself does not perform gas or fluid property calculations. It obtains gas properties from FloBoss firmware, using AGA standards, or from a separate user program installed in the FloBoss. The gas calculation requires you to provide compressibility, gas correction factors, and heating values. For steam, water, or fluid applications, you must install a separate user program to calculate and provide the necessary fluid properties, including density and heating value. The Annubar Calculation program accumulates volume (or mass) and energy and provides the accumulations to the FloBoss 103 to be archived into the periodic and daily databases. Values saved to the historical database will be in the units shown below. Issued Oct-05 1

5 Volume/Mass Units Energy Units Gas volume calculation km 3 GJoules Mass rate calculation 1000 kg GJoules Annubar Flow Calculations The MI-2667 Annubar Flow Calculation program provides an instantaneous flow rate for Annubar installations. In gas applications, the program calculates an instantaneous volume flow rate, corrected to base conditions and provided in m 3 /hour. In steam, water and fluid applications, the program calculates an instantaneous mass flow rate in or kg/hour. Equations used for the gas (volume) and mass calculations are shown below. Gas Volume Equation The program uses the following equation for determining gas volume: q C D P P TC P T K Where: D Internal pipe diameter at working condition Meters Annubar flow coefficient - Expansion factor - K Compressibility coefficient - P Absolute pressure Pa P c Absolute pressure at standard condition Pa P Differential pressure Pa q c Volume flowrate at standard condition m 3 /hour T c Temperature at standard condition Kelvin T Thermodynamic temperature Kelvin с Density at standard condition kg/m 3 C C x 3600 Mass Rate Equation The program uses the following equation for determine mass rate: 2 q m D 2 P x Where: D Internal pipe diameter at working condition Meters Annubar flow coefficient - Expansion factor - P Differential pressure Pa q m Mass flow rate at standard condition kg/hour Density at flowing condition kg/m 3 Issued Oct-05 2
