Meter uncertainty

To ensure continuous accurate measurement, water meters must be calibrated. The calibration
is conducted at Siemens flow facilities with traceable instruments referring directly to the
physical unit of measurement according to the International System of Units (SI).
Therefore, the calibration certificate ensures recognition of the test results worldwide, including
the US (NIST traceability).
