Technical data
10.7 Meter uncertainty
Siemens offers accredited calibrations assured to ISO 17025 in the flow range from 0.0001 m³/
h to 10 000 m³/h.
Siemens Flow Instruments accredited laboratories are recognized by ILAC MRA (International
Laboratory Accreditation Corporation- Mutual Recognition Arrangement) ensuring
international traceability and recognition of the test results worldwide.
The selected calibration determines the accuracy of the water meter. An extended calibration
of the MAG 8000 (7ME6810) sizes DN50 (2") to DN 300 (12") results in a max. ±0.2% of rate
±2 mm/s uncertainty. A calibration certificate is included with every sensor and calibration data
is stored within the meter.
