The OMNI 4000/7000 Series
1.4 Equipment Overview
OMNI 4000s and 7000s are microprocessor-based flow computers that perform liquid and gas
flow calculations in accordance with the methods listed in Section 1.3 Calculations.
The flow computer connects to field transmitters in single and multiple meter run applications
to monitor:
•Liquid and gas flow measurements in the pipeline.
•Custody transfer applications.
The flow computer calculates flow values and displays additional data and measurement
information, which can be transmitted over communication channels and printed, as needed.
In addition, audit trail logs are available for registering changes to measurement parameters and
firmware updates. The audit trail can be printed directly from the front panel of the flow computer
or viewed with the OMNICONNECT software when connected to a computer.
All input/output (I/O) modules are quality tested and temperature trimmed to optimize analog
inputs before the flow computer is shipped.
On-site, OMNI 4000/7000 flow computers are configurable, but not programmable. We do this to
prevent the modification of WELMEC-approved software code, which could render an existing
EC-evaluation certification invalid.
With an OMNI flow computer, the factory-programmed software does not need modification in the
field. This preserves the integrity of existing certifications and provides assurance that software
and firmware have been validated and cannot be modified.
Every OMNI 4000/7000 flow computer has the following components and features:
Hardware
•7201 central processing unit (CPU)
•4.3-inch (10.922 cm) Color LCD with 800
x 480 resolution
•USB Mini-B port on the front panel for
configuring the flow computer
•USB-A Host port on the front panel for
updating the OMNI CPU firmware using a
memory stick
•USB Mini-B port on the CPU for
configuration or updating the OMNI CPU
firmware using OMNICONNECT
•Dual Ethernet (DE) module with:
−2 onboard RJ-45 100 Mbps Ethernet
jacks
−10 Mbps using the back panel
•Expandable to allow for 2 DE modules (4
physical Ethernet ports for a total of 32
virtual connections).
•Expandable to allow for up to 10 Serial
ports with different combinations of DE
and S cards. Must purchase separately.
•Digital I/O Multiplexer (DM) module with
10 independent channels
•Digital I/O channels that support up to 3
externally installed Digital Terminals
(DTs), which can be used in sequence.
Each DT contains 16 I/O points. DTs are

2.OMNI 4000/7000 Overview
The OMNI 4000/7000 flow computer is supplied with firmware and Windows PC configuration
software that allow a single flow computer to perform a wide range of flow measurement tasks
simultaneously, including:
•Multiple meter run totalizing, batching, proving and data archiving.
•Flow and control.
•Communications protocols (selectable) to directly interface with Distributed Control Systems
(DCSs), Programmable Logic Controllers (PLCs) and Supervisory Control and Data
Acquisition (SCADA) host systems.
The flow computer database numbers thousands of data points and provides tight
communications coupling between the SCADA and the metering system.
2.1 Hardware
Front Panel
The front panel of the flow computer features an active alarm Light-emitting Diode (LED), a color
graphics display and a 25-key keypad for navigation, menu, data selection and data entry. The
front panel provides the capability to configure system parameters, view flow data, perform I/O
calibrations and print reports.
Back Panel
All signal I/O terminals and power connector/terminals are located on the back panel. The
OMNI 4000 has four I/O terminal blocks and the OMNI 7000 has ten I/O terminal blocks.
All flow measurement inputs are first received at the back panel and then through plug-in I/O
combination (combo) modules. Four types of combo modules are available: A, B, E and E/D.
Flow computers may be used to interface with any approved compatible 4-20 mA or 1-5 V
temperature, pressure and differential pressure transmitter from the back panel. They can also
receive direct inputs from 4-wire, 100-ohm Resistance Temperature Detectors (RTDs), which
conform to either Deutsches Institut für Normung (DIN) IEC 751 or American curves.
Pulse inputs from any approved turbine, positive displacement or mass flow meter may be used.
Chassis
The chassis houses the I/O modules, the motherboard, the CPU and the power supply.
CPU Module
All custody transfer measurement programs and configurations can be stored in non-volatile
memory for up to 10 years without power. This method prevents damage caused by electrical
noise or tampering with the integrity of calculation specifications, and it does not rely on a battery.

2.2 Firmware
Real-time Operating System
The real-time operating system and Dual Ethernet adapt to load placement, which creates a
high-speed, multitasking environment and quick turnaround on all communications. The operating
system adapts to meet increased demand, and its pre-packaged, certified and standardized code
makes the software easier to maintain.
Cycle Time
The flow computer performs all time-critical measurement functions every 500 milliseconds or
less. For example, the Digital MUX, pulse density and double chronometry critical functions occur
every 10 milliseconds. This cycle time makes measurement calculations more accurate and
permits faster pipeline operations response for critical control functions, such as opening or
closing valves.
Online Diagnostics and Calibration
Diagnostic software is built into the system so that a technician can debug a possible problem
remotely without interrupting online measurement. Technicians can also remotely test Modbus
communications through a unique Modbus register master simulator that is built in-to
the software.
The flow computer has an automatic, two-point calibration system. The operator inputs the high
and low points of the calibrator into the flow computer, which then calculates the calibration.
CPU Firmware
Firmware is stored in flash memory, which is located in the CPU module. The firmware contains
the liquid and gas flow calculations for both metric and US standard units.
Firmware can be updated in two ways:
•With a factory-provided Universal Serial Bus (USB) flash drive
•Through OMNICONNECT when connected to the USB port on the CPU
2.3 Software
OMNICONNECT®
Online or offline configuration of OMNI 4000 and 7000 models is possible using a personal
computer that can run the OMNICONNECT software. This software manages the flow computer’s
configuration, operation, security setup, and supports the updating of the CPU’s firmware.
OMNICONNECT can connect to the flow computer via the Ethernet ports, Serial ports, the front
panel USB port and the CPU USB port.
OMNICONNECT requires a license to run. OMNICONNECT is licensed to the individual PC or
laptop.
