Engineering for measurement Integrity
Flow-meter accuracy alone does not guarantee accurate reported quantities.
Fluid properties, operating conditions, installation effects, secondary instrumentation, flow computation, sampling, calibration and maintenance – all introduce measurement error.
Our approcach is to tailor systems around the measurement objective, process conditions and required level of performance expected. From the process connection through to the final validated and reported quantity.
Our 6 Engineering Pillars for Measurement Integrity:
Measurement performance depends on the combined uncertainty of the entire measurement chain—not only the stated accuracy of the primary meter.
QMI considers:
- Primary meter performance
- Pressure and temperature accuracy
- Density and composition measurement
- Calibration data
- Installation effects
- Flow-computer calculations
- Operating range and repeatability
Where required, uncertainty analysis can identify the dominant error sources and guide meter selection, instrument accuracy, redundancy, calibration intervals and verification requirements.
Changes in pressure, temperature and composition can affect density, viscosity, compressibility and fluid phase.
QMI evaluates:
- Vapour pressure
- Water and hydrocarbon dew points
- Flashing and cavitation risk
- Condensation
- Entrained gas or liquid
- Pressure loss
- Start-up and upset conditions
The system may incorporate pressure control, heating, insulation, separation, filtration, drainage or backpressure control to keep the fluid in the correct condition through the measurement section.
The correct meter must suit the fluid, operating range and required measurement performance.
Selection considers:
- Flow range and turndown
- Pressure and temperature
- Density and viscosity
- Solids or entrained phases
- Allowable pressure drop
- Required uncertainty
- Maintenance requirements
QMI also reviews straight-run requirements, piping geometry, valve location, flow conditioning, vibration, meter orientation and instrument tapping points to create stable and repeatable measurement conditions.
The flow computer converts instrument signals into the final reported quantity.
QMI can configure and verify:
- Pressure and temperature compensation
- Density and compressibility calculations
- Meter factors and calibration coefficients
- Standard volume, mass and energy calculations
- Totalisation and allocation logic
- Alarm and fallback functions
- Data communication and reporting
Validation can include range checking, bad-value detection, meter comparison, analyser validation, totaliser reconciliation and configuration audit trails.
Metering systems must remain capable of being checked throughout their operating life.
QMI considers:
- Meter-prover connections
- Master-meter or check-meter arrangements
- Calibration manifolds
- Instrument isolation
- Test points
- Removable meter sections
- Calibration-gas systems
- Verification procedures
Support can include calibration planning, meter proving, loop testing, flow-computer verification, factory acceptance testing, site testing and performance verification.
A metering system should be practical to inspect, calibrate, maintain and upgrade.
QMI considers:
- Instrument and valve access
- Filter replacement
- Meter removal
- Calibration access
- Drain and vent routing
- Working clearances
- Equipment identification
- Future expansion
Lifecycle support can include commissioning, operator training, calibration support, metering audits, fault-finding, flow-computer changes, brownfield upgrades, obsolescence management, spare-parts planning and documentation updates.
