Performance characteristics

• Maximum permissible error according to ISO/DIN 11631
• Specifications as per measurement report
• Accuracy information is based on accredited calibration rigs that are traced to
ISO 17025.
To obtain measured errors, use the Applicator sizing tool →  150
o.r. = of reading
The measurement error depends on a number of factors. A distinction is made between
the measurement error of the device (0.5% o.r.) and an additional installation-specific
measurement error (typically 1.5% o.r.) that is independent of the device.
The installation-specific measurement error depends on the installation conditions on site,
such as the nominal diameter, accuracy of sensor mounting (sensor holder welding), real
pipe geometry or medium. The sum of the two measurement errors is the measurement
error at the measuring point.

1 Measurement error of measuring device: 0.5% o.r. ± 3 mm/s (0.12 in/s)
2 Measurement error due to installation conditions: typically 1.5% o.r.
3 Measurement error at the measuring point: 0.5% o.r. ± 3 mm/s (0.12 in/s) + 1.5% o.r. = 2% o.r. ±
3 mm/s (0.12 in/s)
