Independent Coriolis flow meter inspection & FAT witnessing
Independent third-party inspection services for Emerson Micro Motion Coriolis mass flow meters, performed on-site in Boulder, Colorado, and representing the customer’s interest at every stage of Factory Acceptance Testing (FAT).
Independent third-party Coriolis inspection services
Coriolis Inspection Services LLC provides independent, third-party inspection and FAT witnessing services for Coriolis mass flow meters manufactured at the Emerson Micro Motion facility in Boulder, Colorado. We act solely on behalf of the customer, ensuring that every test, verification, and certification is performed in accordance with project specifications, applicable standards, and contractual requirements.
Our role is to provide objective oversight during Factory Acceptance Testing. By maintaining an on-site presence at the manufacturing facility, we reduce risk and prevent costly rework after shipment. This gives clients full confidence that their Coriolis meters are ready for installation and operation upon arrival. All inspections are conducted with a strong focus on technical accuracy, documentation integrity, and transparent reporting.
Usually, we witness the following inspections:
- Hydrostatic pressure and leak testing
- Positive Material Identification (PMI) of wetted and pressure-retaining parts
- Calibration testing against traceable reference meters
- Transmitter configuration and parameter verification
- Functional testing of the complete meter system
- Radiographic examination (X-ray / NDT) of flow tubes and welds
- ATEX and hazardous area compliance verification
- Visual, dimensional, and nameplate inspection
- Review and verification of test certificates and quality documentation
Our Coriolis FAT & inspection services
1. Hydrostatic Pressure (Leak) Test
Meters are tested at ≥150% of design pressure using water at ambient temperature. We verify:
- Test pressure level
- Hold duration
- Zero leakage
- Structural integrity
✔ Deliverable: Hydrostatic Leak Test Inspection Certificate
2. Positive Material Identification (PMI)
We oversee non-destructive alloy verification using XRF or OES analyzers to confirm ASTM compliance and prevent material substitution. Common Corrosion-Resistant Alloys inspected:
- 316L Stainless Steel
- Alloy C-22
- Alloy C-276 (Hastelloy / UNS N10276)
- Alloy 686
✔ Deliverable: PMI Inspection Report (Elemental Composition Results)
3. Calibration Test
Accuracy is verified against traceable reference (etalon) meters across the customer-specified flow range. We confirm:
- Accuracy performance
- Repeatability
- Calibration certificate validity
✔ Deliverable: Calibration Certificate Review & Witness Confirmation
4. Configuration Test
We verify transmitter-to-sensor integration and parameter setup. Includes:
- Transmitter configuration check
- Communication verification
- Parameter validation
✔ Deliverable: Configuration Test Report
5. Functional Test (Calibration + Configuration)
Complete system verification ensuring:
- Accurate flow measurement
- Proper electronic functionality
- System performance integrity
✔ Deliverable: Functional Test Report
6. Radiographic Examination (X-Ray / NDT)
Industrial radiography oversight to detect internal weld defects and volumetric flaws in high-pressure flow tubes.
✔ Deliverable: Radiographic Examination Inspection Certificate
7. ATEX & Hazardous Area Verification
For explosive environments, we verify:
- Correct ATEX / IECEx nameplate markings
- Valid EC-Type Examination Certificates
- Compliance with hazardous area requirements
✔ ATEX compliance confirmation included in the final report.
8. Visual & Dimensional Inspection
Final inspection against:
- Purchase Order
- Data Sheets
- Technical specifications
Includes tag verification, serial number confirmation, nameplate inspection, and workmanship review.
Why independent inspection matters
Coriolis mass flow meters are not ordinary instruments. In many facilities, they determine custody transfer quantities, production volumes, blending accuracy, and regulatory reporting values. In practical terms, they directly influence revenue. Coriolis meters measure mass flow, density, and temperature directly. Even a small calibration deviation, material non-conformance, or overlooked configuration error can have long-term financial consequences.
Independent third-party inspection reduces that risk.

What are Coriolis mass flow meters?
Coriolis mass flow meters measure mass flow, density, and temperature by detecting Coriolis forces generated in vibrating tubes as fluid flows through them.
Key advantages include:
✔ Direct mass flow measurement
✔ Extremely high accuracy
✔ Insensitivity to pressure changes
✔ Ideal for custody transfer and critical process control
