Measurement Report
If required, the device can be supplied with a 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 15 (½"), DN 25 (1"), DN 40 (1½"), 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]:
Repeatability
Max. ± 0.3% for flow velocities > 0.3 m/s (0.98 ft/s)
