Days spent assembling evidence that already existed
The information was complete. What was missing was a system that could bring it together on time.
ACCURAX ENGINEERING Measurement software and consulting
The complete technical history of your measuring equipment, in one place
Certificates, calibrations and compliance—without chasing paperwork
Accurax centralizes certificates, manuals, equipment histories and due dates, keeping every record searchable, traceable and audit-ready.

Two software products and engineering consulting
ACCURAX MetriVault
Do your instruments conform?
Centralizes and uses OCR to read equipment evidence, then evaluates conformity against the maximum permissible error under ISO 10012, ISO/IEC 17025 and JCGM decision rules.
Technical records + conformity →ACCURAX MetriSigma
What is the measurement uncertainty?
A GUM-based uncertainty calculation engine for six flow measurement technologies—including Coriolis, ultrasonic and Venturi.

The certificate exists. The question is where
Someone asks for a meter certificate. It may be in a shared folder, in the buyer’s inbox or in a spreadsheet someone maintained until they stopped. As long as everything works, nobody notices.
A due calibration is discovered on the same day
Measurements then have to be defended, repeated or justified to the regulator.
When the person leaves, the map leaves too
Knowing which certificate belongs to which instrument—and which version is current—lives in one or two people’s heads.

MetriVault: do your instruments conform?
MetriVault centralizes and reads with OCR all technical evidence for your measuring equipment—certificates, manuals and equipment histories—and uses it to determine, at any time, whether an instrument is fit for operation. It is not a document archive; it is the system that interprets those documents.
Audit preparation
up to 70% less time preparing for audits
Assemble the dossier in hours, not days: MetriVault brings together certificates, due dates and conformity already linked to each instrument, ready to present.
Accurax estimate; measured against your own operation during the pilot.
Centralize and read with OCR
Certificates, manuals and histories for every instrument: OCR extracts the data and organizes it according to your plant’s actual hierarchy.
Technical document managementMonitor due dates
Alerts before a calibration expires, prioritized by the criticality you assign to each instrument.
Calibration alertsDetermine conformity
Evaluates the instrument against its maximum permissible error and operating limits using a traceable decision rule.
Conformity: ISO 10012 · 17025 · JCGMEvaluates conformity under a decision rule—simple acceptance, a guard band with shared risk, or a guard band based on consumer risk—while accounting for uncertainty, as required by ISO 10012, ISO/IEC 17025 and JCGM. Configurable by measurement quantity.

MetriVault is not just a repository
A document management system stores the certificate. A CMMS schedules maintenance. MetriVault understands what the certificate says: which instrument it belongs to, when it expires and whether it meets the requirement.
| System | What it does | What it does not do |
|---|---|---|
| Document management SharePoint · M-Files · DocuWare | Stores and versions files | Does not know what the certificate contains or when it expires |
| CMMS Fiix · MaintainX | Schedules asset maintenance | Does not manage metrological evidence or uncertainty |
| ERP SAP · Dynamics | Records the asset as an accounting line item | Does not retain its technical history or regulatory compliance |
| PDF chatbot Generic assistants | Answers in natural language | Does not guarantee a verifiable source or audit-grade evidence |
| MetriVault | Reads the certificate, links it to the instrument, monitors the due date and evaluates conformity against ISO 10012, ISO/IEC 17025 and JCGM | Does not replace your ERP or CMMS; it integrates with them |

What the MetriVault guided pilot includes
The pilot is a real, bounded implementation: we select one area of your operation, load your actual instruments and certificates into MetriVault, and leave the platform running with them. It is not a demo or a test using sample data.
It answers one question before you commit to a full implementation: does this truly manage my metrological operation, with my real data? You will know from evidence—not a promise.
Scope
- 1 critical area or process, defined with you
- 1 primary document type
- Up to 300 instruments or pieces of equipment
- Up to 5 users from your team
What you receive
- An equipment status dashboard using your operational data
- Active calibration alerts from day one
- Source-cited search across your documents
- Hands-on support from our team throughout the pilot
Pilot pricing is defined during the assessment based on document volume and the agreed scope.

How we measure whether the pilot worked
The pilot does not end with a demonstration. It ends with three metrics agreed before kickoff and measured at closeout. If they do not move, the pilot did not work.
Time to assemble an audit file
Measured before and after using the same audit. The target is agreed with you during the assessment.
Due dates identified in advance
No calibration due date discovered on the same day for equipment included in the pilot.
Document coverage
Percentage of instruments with complete, current evidence, measured at the start and at closeout.
Every pilot is measured against your own operational baseline, not a market average. You define the numbers before we start—and we verify them together at closeout, on your real instruments and documents.
ACCURAX MetriSigma Product 2 · Measurement uncertainty

MetriSigma: the uncertainty of every measurement
Declaring conformity is one requirement; estimating measurement uncertainty is another, and they apply to different use cases. That is why it is a separate product: MetriSigma, Accurax’s uncertainty calculation engine.
MetriSigma
Six measurement technologies with GUM-based calculations
CoriolisUltrasonic gasVenturi gasGas orifice plateLiquid turbineStatic liquid
GUM-based estimation using data extracted directly from the certificate, with no manual recapture. The result remains traceable to its source: the instrument, certificate and contribution used in every term.
