V-Cone Metering Program User Manual (for ROC800-Series)
Chapter 1 – Introduction
This chapter describes the structure of this manual and presents an
overview of the V-Cone® Metering program for the ROC800-Series
Remote Operations Controller (ROC800).
1.1 Scope and Organization
This document serves as the user manual for the V-Cone Metering user
program, which is intended for use in ROC800. This manual describes
how to download and configure the V-Cone Metering user program
(referred to as the “V-Cone program” or “the program” throughout the rest
of this manual). You access and configure the program using ROCLINK
800 Configuration Software (version 2.00 or greater) loaded on a personal
computer (PC) running Microsoft® Windows® 2000 (with Service Pack 2),
Microsoft Windows XP, Microsoft Windows Vista™, or Microsoft
Windows 7 (32-bit or 64-bit).
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 ROC800, 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 ROC800 units and
their configuration. For more information, refer to the following manuals:

1.2 Product Overview
The V-Cone program allows a ROC800 to calculate a corrected
volumetric flow rate at a specified base pressure and temperature for a
McCrometer V-Cone or Wafer-Cone flowmeter. The V-Cone or WaferCone flowmeter is very similar to an orifice plate calculation, uses many
of the same configuration parameters, and produces many of the same
calculated values. For this reason, the user program makes use of existing
orifice meter run points already provided by the ROC800 firmware. In
addition to the standard orifice point parameters, the ROC800 also
calculates an actual volumetric flow rate, a fluid velocity, a thermal
expansion factor, and the percent pressure loss in accordance with the
(part D301217X012).

McCrometer specification McCrometer Flow Calculations for the V-Cone
Flowmeter, October 2002.
As part of the V-Cone program point configuration, you assign the VCone or the Wafer-Cone calculation to an orifice meter point. When the
calculation is assigned, the standard AGA3 calculation is bypassed and the
McCrometer calculation is performed instead. All standard orifice
parameters, as well as the additional V-Cone program parameters, are
available for assignment to Modbus registers, PID control loops, historical
archiving, and FST and DS800 database functions.
1.3 Program Requirements
The V-Cone program version 1.11 is compatible with ROC800-Series 2
firmware version 3.30 (or greater), ROC800-Series 1 firmware version
2.16 (or greater), ROC800L firmware version 1.20 (or greater), and with
version 2.00 (or greater) of ROCLINK 800 configuration software. The
program requires you to install an AGA 3/7/8 hardware-based license key
to enable the calculations, and a V-Cone license key to enable the user
program.

Notes:
Two versions of the program are included. Installation and operation
are identical between the two programs, but they use different point
type locations, different display numbers. V-Cone.61.tar uses point
types 61 and uses display 61. V-Cone.71.tar uses point types 71 and
uses display 71. Install the program version that avoids point type
conflicts with currently installed programs.
The installation process and functionality is the same for all versions
of the V-Cone program.

1.3.1 License Keys
License keys, when matched with valid license codes, grant access to
applications such as the V-Cone program. An AGA3/7/8 license key must
be present to provide the required number of meter runs, and a separate
license key is also required to enable the V-Cone user program.
The term “license key” refers to the physical piece of hardware that can
contain up to seven different licenses (refer to Figure 1–1). Each ROC800
can have none, one, or two license keys installed. If you remove a license
key after enabling an application, the firmware disables the task from
running. This prevents unauthorized execution of protected applications in
a ROC800.

Chapter 3 – Configuration
After you have loaded the V-Cone program, you configure it using
ROCLINK 800 software. Most of the configuration for the V-Cone meter
is done through the standard orifice meter setup screen and the station
setup screen for the station to which the orifice meter belongs. For more
information, refer to ROCLINK 800 Configuration Software User Manual
(for ROC800-Series) (part D301250X012).
To do this, you use one program-specific screen (V-Cone Configuration)
and two standard ROCLINK 800 screens (Orifice Meter Setup and Station
Setup):
Use the V-Cone Configuration screen to enable, select the
McCrometer type along with the corresponding flow coefficient, and
assign the V-Cone calculation for a specific meter run.
Use the Station Setup screen to configure parameters common to
multiple meter runs.
Use the Orifice Meter Setup screen to configure parameters for a
single meter run for use with the V-Cone program.
Use the Orifice Values screen to view values calculated by the V-Cone
program.
