Liquid calibration is performed with water or other liquids under controlled temperature and flow conditions representative of utility and energy applications.
Calibration and verification
Accredited calibration of liquid and thermal energy meters
Verify liquid and thermal energy measurements under controlled conditions and document the stable, traceable performance of the meters.
Unstable or undocumented flow measurements create uncertainty in liquid and thermal energy metering used for settlement and operational monitoring. Flow calibration actively tests how meters respond under defined flow and temperature conditions and documents performance, traceability and stability over time.
Accredited calibration
The service targets water utilities, district heating and cooling operators, and meter manufacturers that must prove accurate flow data for settlement, process control and regulatory compliance. Our accredited laboratory and on-site calibration use reference systems to detect drift, temperature effects, and installation influences. The service is part of our expertise area Calibration and verification.
The results deliver clear evidence of meter behaviour, support technical decisions, and provide reliable documentation for audits, quality systems, and regulatory purposes.
Challenges
When liquid flow measurements are uncertain, settlement, compliance and process reliability suffer.
Unverified meter accuracy leads to settlement risk
Without recent calibration, flow meters may drift unnoticed, creating uncertainty in billing, energy settlement and internal accounting.
Process conditions mask measurement errors
Changes in temperature, viscosity or installation conditions can affect meter performance, making on-site results differ from expected values.
Incomplete traceability weakens audit readiness
Missing or outdated calibration records make it difficult to demonstrate traceability to standards during audits or regulatory reviews.
Large or installed meters are hard to validate
Meters that cannot be removed from service are often left unchecked, increasing operational risk and uncertainty over long-term stability.
Benefits
Ensure stable, traceable flow measurements for settlement, audits and process control
Low uncertainty, clearer decisions
Accredited calibration with traceability to primary standards reduces measurement uncertainty and strengthens confidence in settlement, billing and process data.
Stable meter performance, fewer deviations
Calibration under controlled flow and temperature conditions reveals drift, wear or installation effects early, helping prevent downstream quality or settlement issues.
Flexible setups, smoother operations
Laboratory and on-site calibration options allow meters to be tested where it fits operations best, reducing disruption and ensuring representative measurement conditions.
