Best Practices in Custody Transfer Flow Measurement

Custody Transfer Meter

Delivering Measurement Certainty with Standards-Driven System Integration

In the oil and gas industry, custody transfer flow measurement is not just about volume—it’s about value, accountability, and trust. Every cubic meter measured represents a commercial transaction between producers, transporters, and customers. Inaccuracy, even in small margins, can lead to revenue loss, disputes, and compliance issues.

As India’s energy sector expands—across pipelines, LNG terminals, CGD networks, and refining infrastructure—the importance of reliable, auditable, and compliant custody transfer systems cannot be overstated.

At EXIMP, we specialize in designing, engineering, and integrating custody transfer flow measurement systems—built around international standards, selected from best-in-class global OEMs, and tailored to the specific requirements of each site and stakeholder.

What Custody Transfer Measurement Requires?

Custody transfer involves the physical handover of fluids—natural gas, steam, crude oil, or refined products—between two commercial entities. It demands:

  • High-accuracy metering
  • Certified instrumentation
  • Environmental compensation
  • Transparent validation and traceability
  • Compliance with standards like API, ISO, OIML, AGA, PNGRB

But it’s not just about installing a meter. It’s about designing an integrated, verifiable measurement system that ensures accuracy over time, not just at commissioning.

Best Practices — Engineered into Every System

1. Select Meters Based on Application Fit — Not Commercial Preference
Whether it’s ultrasonic, coriolis, turbine, or differential pressure, meter selection must match the process conditions and commercial use case—not a preferred product list.
Our Approach: We remain vendor-neutral and select the optimal meter type and brand for each application, ensuring the right solution—not just the available one—is delivered.

2. Design Around Standards, Not Shortcuts
Measurement integrity depends on adherence to API MPMS, ISO 5167, OIML R117, and other applicable norms.
Our Approach: Every system we design—from meter runs to flow computers and signal processing—follows the governing standard to the letter, and we document it for audit purposes.

3. Build in Calibration and Validation from Day One
Custody transfer systems must support periodic calibration and validation through on-site proving, remote diagnostics, or condition-based monitoring.
Our Approach: We integrate traceable validation options including flow computers with auto-diagnostics, dual-metering configurations, or CBM tools—ensuring long-term measurement assurance.

4. Integrate for Lifecycle Performance, Not Just Commissioning
A flowmeter is only one part of the system. Communication reliability, sensor redundancy, diagnostic access, and data integrity must all be part of the design.
Our Approach: We deliver complete custody metering packages—with mechanical, electrical, and control system integration, plus full documentation and digital audit trails.

5. Offer End-to-End Support—Across Brands and Technologies
Many buyers worry about post-sale support and prefer going directly to OEMs. While understandable, this often leads to siloed ownership and finger-pointing when problems arise.
Our Approach: As integrators, we take system-level responsibility. We coordinate directly with OEMs, manage warranty and service across brands, and offer a single point of contact for the end user. We don’t replace OEM support—we enhance it with a layer of accountability, context, and continuity.

Where We Add Value?

As a Measurement System Integrator, We Provide:

  • Custom-Engineered Metering Skids for gas, steam, and liquid
  • Certified Instrumentation from leading global OEMs
  • Flow Computers and Control Panels built to site-specific I/O and protocols
  • Real-Time IIoT Monitoring with Tek-Cloud, C-SMART, and flare.IQ integration
  • Calibration & Validation Services, traceable to NABL/NIST
  • Wet Gas and Flare Measurement with diagnostics per ISO/TR 12748, 11583
  • Project Engineering, Documentation & Regulatory Compliance Support

Why Choose a System Integrator Over a Product Vendor?

Final Thought

Custody transfer is too important to leave to chance—and too complex to depend on one product. By partnering with a vendor-neutral measurement system integrator, you gain:

  • A technically optimal solution
  • Compliance confidence
  • Lifecycle support
  • A single accountable partner

At EXIMP, we don’t sell meters. We build certainty around measurement.
