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 > 0.3 m/s (1 ft/s) and a Reynolds number > 10000, the following are typical error limits:
Nominal diameter Device error limits
DN 15 (½") ±0.5 % o.r. ± 5 mm/s
DN 25 to 200 (1 to 8") ±0.5 % o.r. ± 7.5 mm/s
> DN 200 (8") ±0.5 % o.r. ± 3 mm/s
o.r. = of reading
Measurement Report
If required, the device can be supplied with a factory measurement report. To certify the
performance of the device, a measurement is performed under reference conditions. Here, the
sensors are mounted on a pipe with a nominal diameter of DN 50 (2") or DN 100 (4") respectively.
The measurement report guarantees the following error limits of the device
[at a flow velocity > 0.3 m/s (1 ft/s) and a Reynolds number > 10000]:

DN 50 (2")
DN 100 (4")
