• Error limits following ISO/DIS 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 →  75
Maximum measured error o.r. = of reading
The measured error depends on a number of factors. A distinction is made between the measured
error of the device (0.5% o.r.) and an additional installation-specific measured error (typically 1.5%
o.r.) that is independent of the device.
The installation-specific measured error depends on the installation conditions on site, such as the
nominal diameter, wall thickness, real pipe geometry or medium. The sum of the two measured
errors is the measured error at the measuring point.

 23 Example of the measured error in a pipe with a nominal diameter DN > 200 (8")
1 Measured error of the device: 0.5% o.r. ± 3 mm/s (0.12 in/s)
2 Measured error due to installation conditions: typically 1.5% o.r.
3 Measured 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)
Measured error at the measuring point
The measured error at the measuring point is made up of the measured error of the device (0.5%
o.r.) and the measured error resulting from the installation conditions on site. Given a flow velocity
of > 0.3 m/s (1 ft/s) and a Reynolds number > 10 000 the following are typical error limits:

Measurement report
If required, the device can be supplied with a factory measurement report. A measurement is
performed under reference conditions to verify the performance of the device. Here, the sensors are
