OMNI 6000 Flow Computer with Operator Display
Overview: The Industry Standard for Fiscal Flow Measurement
The OMNI 6000 Flow Computer is a modular, configurable device purpose-built for custody-transfer and fiscal flow measurement across oil and gas applications, from offshore production facilities to crude oil, refined products, LPG, NGL, and gas transmission pipelines. Equipped with a 32-bit processor and a front-panel operator display with full keypad, the OMNI 6000 supports single or multi-run configurations and can be tailored to turbine, positive displacement, Coriolis, orifice, and gas metering systems through selectable firmware revisions.
As an authorized supplier of OMNI Flow Computers instrumentation, Seven Star LLC sources and supplies the OMNI 6000 flow computer to refineries, gas processing plants, storage terminals, and marine loading facilities across Oman and the wider GCC. Because custody-transfer measurement carries direct financial and contractual consequences, Seven Star LLC helps engineering teams configure the correct I/O module mix and firmware revision for their specific metering application.
Measurement Principle
The OMNI 6000 processes flow measurement inputs – pulse, analog, and digital transmitter signals – through 14-bit A/D converters with temperature-trimmed accuracy and photo-optical isolation on each I/O point, eliminating the multiplexers and potentiometers that introduce drift and error in less rigorously engineered flow computers. Meter pulse fidelity checking continuously verifies that pulse signals from turbine or PD meters are being counted correctly, a critical safeguard in custody-transfer applications where an undetected pulse-counting error translates directly into a measurement and financial discrepancy.
Firmware revisions available on the OMNI 6000 support turbine, positive displacement, and Coriolis liquid flow metering with K-factor or meter-factor linearization, orifice and differential pressure liquid flow metering, and orifice/turbine gas flow metering, all compliant with API, AGA, ISO, and OIML measurement standards. This standard, field-proven firmware approach means custody-transfer calculations do not require custom programming, reducing both commissioning time and the audit risk associated with proprietary calculation logic.
Engineering Design of the OMNI 6000
The OMNI 6000 accommodates up to 10 I/O connectors and supports plug-in, assignable digital, serial, and combination I/O modules, including Honeywell and Rosemount digital transmitter interface modules and HART digital transmitter interface modules for direct smart-transmitter integration. An Ethernet communications module supports network connectivity, and Modbus peer-to-peer communications up to 38.4 kbps allow integration with a plant PLC or DCS, while dual LEDs on each digital I/O point provide clear active/fused status indication for field troubleshooting.
With a boot-up time of under one second and a catastrophic MTBF (Mean Time Between Failure) greater than 8,000 days, the OMNI 6000 is engineered for continuous, uninterrupted measurement even through unexpected voltage spikes or power dips – conditions that would force many competing flow computers to reload their operating system and lose measurement continuity. The included OMNICOM configuration software is the single Windows program required to perform any task on the OMNI, with no high-level back-door programs that could compromise the integrity of the core flow computer software.

Industrial Applications
The OMNI 6000 is deployed across offshore oil and gas production facilities, crude oil and refined products pipelines, LPG, NGL, and gas transmission lines, storage and marine loading/offloading terminals, and refinery and petrochemical custody-transfer measurement points. Its combination of rugged construction, standards compliance, and proven long-term reliability has made it a long-standing reference platform in fiscal and custody-transfer flow measurement worldwide.
Seven Star LLC supports refinery instrumentation teams, terminal operators, and gas processing facilities across Oman, Muscat, Sohar, and the broader GCC region with sourcing of OMNI flow computers, helping projects maintain defensible, standards-compliant custody-transfer measurement.

I/O Capacity and Module Selection
Across those connector positions the OMNI 6000 is designed to accept up to 24 input signals using six field I/O (Combination) modules, including up to two serial SV modules, together with two 12-channel digital I/O modules and up to three communications modules in any mix of serial and Ethernet. That configuration is what allows a single chassis to serve up to four meter runs, and it is the practical reason the OMNI 6000 is specified over the smaller OMNI 3000, which accepts only two Combination modules, one digital module and one communications module. Each digital channel is individually configurable as an input or an output for status, command, pulse output, sampler grab and prover sphere detector duties, with a current capacity of 200 mA per point and 500 mA per digital module.
On the communications side a total of ten ports can be configured – up to eight RS-232/485 and up to two Ethernet in combination – with each Ethernet port supporting eight concurrent sockets and access security by password, MAC address, IP address or IP range. Smart-device connectivity is selected by hardware module: HART, Honeywell DE and Rosemount or Coriolis multivariable interfaces each require their specific module, after which the OMNI firmware implements the protocol and register map automatically for the device type chosen. Within the OMNI Flow Computers line the 3000/6000 platform remains the long-serving standard, while the higher-capacity OMNI 7000 addresses larger multi-stream installations.
Firmware Revisions and Metrological Approvals
Application firmware for the OMNI 6000 Flow Computer is selected first by measurement units, then by fluid, then by primary meter type. Revision 20 (US Customary) and Revision 24 (Metric) cover turbine, PD, ultrasonic and Coriolis liquid applications with K-factor linearization; Revision 22 and Revision 26 cover turbine, PD and ultrasonic liquid applications with meter-factor linearization; and Revision 23 and Revision 27 cover gas measurement by DP – orifice, Venturi, cone and nozzle – as well as turbine, ultrasonic and Coriolis gas metering. Calculations run on a fixed 500 ms cycle in 64-bit double precision, with totalization integrity protected by triplicated register storage and checking.
Flowmeter pulse inputs are checked to API MPMS Chapter 5.5 Level A fidelity, and all analog inputs and outputs are optically isolated from the computer logic supply with a maximum common mode voltage of ±250 VDC to chassis ground. Beyond UL, CSA and CE marking, the platform carries European MID approval under Directive 2004/22/EC, OIML R117-1, OIML D031, EN 12405 Part 1 and WELMEC 7.2 and 8.8, with further approvals available from NMi, Measurement Canada, INMETRO, GOST, PAC, Indian Weights and Measures and LNE. For fiscal metering skids in Oman and the GCC, that approval portfolio is frequently the deciding factor when a custody-transfer measurement system must satisfy both the buyer and the seller of the product being transferred.
