Data SheetOMNI 3000E & 6000EFlow Computer OMNI FLOW COMPUTERFor more than 25 years, OMNI flowcomputer has been considered to be thebest flow computer available forperformance, reliability, support, andlifecycle.PERFORMANCEOMNI flow computers are designed to meetthe measurement needs of the oil and gasindustry. When AC or DC power is appliedto the OMNI, it is available and ready formeasurement in less than one second. TheOMNI is not hindered by inefficient, slowloading, memory-hungry operating systems,intended for the PC, mobile phone, tablets,or other devices. The OMNI’s highlyefficient firmware integrates with bulletproofhardware and is designed solely formeasurement of custody transferapplications. The OMNI exceeds allrequirements for data processing, accuracy,and calculation cycle time for all recognizedstandards bodies, including API, ISO, OIML,and AGA. Coupled with the largest flowcomputer specialist support team andunique on-line support tools anddocumentation, the OMNI continues to bethe first choice of industry experts.RELIABILITYThe OMNI has mean time between failures(MTBF) of greater than 8,000 days. This isnot a theoretical calculation or an arbitraryOMNI FLOW COMPUTERS, INC.www.omniflow.comPage 1 of 13statement, but actual field performance data.We have documented cases of exposure tolightning strikes, hurricanes, waterimmersion, and even a car crash.OMNI serial numbers 001, 002, 003, and004, produced in 1991, are still in dailyoperation. Although they are somewhatdifferent to today’s OMNI in certain areas offunctionality, they can be upgraded tocurrent factory specifications at any time.We believe we are the only flow computermanufacturer who can make this claim.SECURITYThere are always at least two parties to ameasurement transaction, which mightinclude: buyer, seller, field owners, orgovernment regulator. It does not matterwhat task your flow computer is performing– custody transfer, allocation, royalty,pipeline, ship loading, utilities, or LACT –compliance to the contractually agreedmeasurement standards is the responsibilityof the system operator. Even the slightestdiscrepancy over time can cost hundreds ofman-hours, or at a minimum, hundreds ofthousands of dollars.When flow computers have an “open” or“programmable” architecture it opens thedoor for the manufacturer’s calculations tobe compromised, edited, or modified in avariety of ways. The traceability to anyapprovals a device may have previouslyobtained can be overwritten, manipulated, or
Data SheetOMNI 3000E & 6000E Flow Computersimply avoided during applicationprogramming by the manufacturer orintegrator. Even the simple audit offirmware revision and checksum forcompliance could require the completeverification of all the flow computercalculations and functions. Only OMNIgives you the assurance that what isimplemented at the factory is what is beingused in the field for your measurement andapplications. Buyer, seller, auditor, andregulator alike need to have the sameassurance and peace of mind.CONTINUITYWithout changing its familiar constructionand easy-to-use menu navigation, every partof the OMNI undergoes continuousdevelopment. OMNI manages all parts of itsproduct design, development,manufacturing, and distribution 100% underone roof. This guarantees that all advancesin technology are incorporated by specialistsand are backward compatible. You do nothave to buy a new computer every fewyears with the hidden engineering costs,training and adoption time associated withbuying an all new device nor with the costsassociated with obsolescence to yourcontrol system. With an OMNI you simplyupgrade internal hardware and firmware.OMNI does not use a third-party PCoperating system such as Windows orLinux. These operating systems wereintended for short lifetime consumer marketssuch as PCs, mobile phones, and otherdevices, and are not designed with asupported lifecycle of 15 or 20 years. OMNIusers are not at the mercy of third-partysuppliers of “freeware” who may decide tostop supporting key system utilities andobsolete your flow computer overnight, longbefore its end of lifecycle.TRACEABILITYOMNI recognizes that most flow computermanufacturers, integrators, and even usersare not qualified and experienced embeddedOMNI FLOW COMPUTERS, INC.www.omniflow.comPage 2 of 13software developers and programmers. Forthis reason, OMNI does the programming,testing, and verification. Three quick stepsdetermine what standards and tasks the flowcomputer is performing. Simpleconfiguration, never programming, is all thatis required to install, operate, and maintainan OMNI. We take responsibility for oursoftware implementation. We do notdelegate this to others, least of all our users.This is the real significance ofISO9001:2008 quality assurance.AFFORDABILITYThe OMNI represents reliability, stability,and security. Without constant designchanges or frequent software updates, youdon’t lose time, money and measurement asa result of manufacturer or integratorinexperience or product changes.APPLICATIONS Crude oil Refined products LPGs Anhydrous ammonia Ethylene Chemical Natural gas NGLs Specialty gases Water and steam product selectionCOMMUNICATIONSIn today’s modern and changing ITenvironment, flexibility in communications isan essential consideration for your choice offlow computer.

This includes the abilityto upload or download OMNICOM files andchange meter factors.In addition to the customary multiple levelfront panel security, it is now possible toassign each device connected to acommunications port with its own user name(PLC, SCADA, etc.) and password.Auditing and AlarmsFull auditing of all configuration changesirrespective of the origin – including fromcommunication links, front panel,programming statement results, orOMNICOM – are captured with date/timestamp, the origin, and totals at the time ofchange.OMNI FLOW COMPUTERS, INC.www.omniflow.comPage 6 of 13The results of Boolean and Variablestatements can now be viewed live, inreal-time.For further information on the OMNI 3000Eand 6000E please contact OMNI Sales.
Data SheetOMNI 3000E & 6000E Flow ComputerSUMMARYOMNI pioneered flow computing based on maintaining a fixed calculation cycle time rather thantask loading. Today’s OMNI flow computer still maintains a measurement calculation cycle timeof 500mS that exceeds any industry requirements. Calculations are carried out in doubleprecision (64-bit), floating point format for greatest accuracy. Totalization integrity is assuredthrough the well-established industry practice of triplicated (Tri-reg) storage and checkingroutines.The modular design lets you buy the hardware you need for any given application. A ModelDesign document is available for further information. When you need to add an additional meterrun, simply add any other I/O modules you need.“Future-Proof” is a term used freely by our competitors, yet subject to considerable doubt inpractice. OMNI has demonstrated “future-proof” since 1991. Even OMNI flow computers in longterm service are backward compatible through upgrade paths to today’s specifications, approvalsand customer requirements.OMNI FLOW COMPUTERS, INC.www.omniflow.comPage 7 of 13
