conditions
Error limits following ISO/DIN 11631:
20...30 °C, 2...4 bar, Calibration rig traceable to national standards
Calibration with the corresponding process connection of the respective norms
Maximum measured error • Liquid (volume flow):
< 0.75% o.r. for Re > 20’000; < 0.75% o.f.s for Re between 4’000...20’000
• Gas/Steam (volume flow):
< 1% o.r. for Re > 20’000; < 1% o.f.s for Re between 4’000...20’000
• Temperature:
< 1 °C (T > 100 °C, saturated steam); rise time 50% (stirred under water, following IEC 60751): 8 s
• Mass flow (saturated steam):
– for flow velocity v 20...50 m/s, T > 150 °C (423 K)
< 1.7% o.r. (2% o.r. for remote version) for Re > 20’000
< 1.7% o.f.s (2% o.f.s for remote version) for Re between 4’000...20’000
– for flow velocity v 10...70 m/s, T > 140 °C (413 K)
< 2% o.r. (2.3% o.r. for remote version) for Re > 20’000
< 2% o.f.s (2.3% o.f.s for remote version) for Re between 4’000...20’000
• Mass flow (other fluids):
Depends on the quality of the pressure value specified in the device functions.
An individual error observation must be carried out.
o.r. = Of reading, o.f.s = Of full scale, Re = Reynolds number
