Meteringsmethode

Meteringsmethode is the Dutch term for the systematic procedure used to determine a quantity by measurement. It specifies how a measurement is planned, performed, recorded, and evaluated. Meteringsmethode is applied across science, industry and public administration to produce reliable, reproducible results. Measurements can be direct, where the quantity is read from an instrument, or indirect/derived, where the value is inferred from a model, calibration or multiple measurements.

A metering method typically includes the choice of instrument, a defined procedure, a sampling plan, calibration and maintenance, data processing, and an assessment of measurement uncertainty. Traceability to recognized standards or reference materials is essential to ensure comparability and legal admissibility.

Methods are often categorized as direct (the quantity is measured with a suitable instrument) or indirect (the quantity is inferred via relationships to other quantities). They can be further distinguished by context (laboratory versus field), by the type of data (quantitative versus qualitative), and by whether the method is primary (no reference artifact required) or secondary (requires calibration against a standard). Non-destructive methods, destructive testing, and in-situ measurements are common variants.

Developing a metering method involves defining the measurement quantity and required accuracy, selecting appropriate instruments and procedures, and validating the method through tests and uncertainty analysis. Standards such as the Guide to the Expression of Uncertainty (GUM), ISO/IEC 17025, and sector-specific guidelines provide frameworks for documentation, calibration, and traceability.

Applications range from industrial quality control and environmental monitoring to energy metering and financial metrics. The choice of method affects reliability, cost, and regulatory compliance, making thorough method design and ongoing verification essential.
