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. A MAG 8000 (7ME6810)
standard calibration results in max. ±0.4% of rate ±2 mm/s uncertainty. A MAG 8000
(7ME6880) standard calibration results in max. ±0.8% of rate ±2.5 mm/s uncertainty. 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.
