AUTOMATED MEASUREMENT SYSTEMS
ENGINEERING DESIGN
Recommendations
📑 Introduction
Designing measurement systems, FCMS, and automation is a core activity of Pro meter and its partner SIA Olimps. We provide not just a project, but a fully implementable solution — metrologically verified, legally supported, and ready for operation.
What we design:
- Oil, gas, and petroleum product measurement systems
- FCMS (cabinets, provers, quality blocks)
- Automated control systems, SCADA algorithms
- Project documentation according to GOST, OIML, ISO
Our approach:
We apply modular solutions: ready-made blocks (filtration, measurement, control, Preset controllers) are manufactured and tested at the factory, and delivered fully assembled to the site.
- Reduced installation time
- Lower risks during commissioning
- Improved quality and reproducibility
Important: we adapt proven solutions to operating conditions, not the other way around. This ensures a balance between engineering logic and the ToR.

5. Legal Validity of Project Documentation
📌 For most Clients, it is not only the technical solution that matters, but also its legal enforceability.
Each of our projects — both factory and regional — is accompanied by formal documentation that satisfies contracting authorities and international partners.
📄 The Project Is Part of the Contract
Each stage (factory or regional project) is included in supply, construction, or modernization contracts.
Our documentation covers:
– Equipment specifications
– Measurement methodology
– Legal justifications
– Data processing algorithms
This documentation becomes part of the tender, contract, and technical acceptance.
✏ Changes — Only via Amendments
Any changes to the CMF system, logic, software, or structure must be recorded via signed amendments to the project.
We recommend that project documentation be included in the Customer’s contract to legally fix such changes — preventing future disputes.
🛡 Risk Mitigation and Legal Protection
At this stage, the project acts as:
– A regulatory and legal shield for the Client;
– A base for registration in national systems;
– A reference for auditing, litigation, and arbitrage.
We help avoid scenarios that often result in legal disputes (e.g. undocumented changes, obsolete methods, or informal recalculations).
✅ What the Client Receives:
– Instructions, diagrams, and metrological justifications;
– Documentation in local languages (Russian, Latvian, English);
– Certified calculations based on national and international standards;
– Calibration protocols and metrological validation;
– Arbitration support (if needed).
