Temperature
• Saturated steam and liquids at room temperature if T > 100 °C (212 °F) applies: <
1 °C (1.8 °F)
• Gas: < 1 % o.r. [K]
• Volume flow: > 70 m/s (230 ft/s): 2% o.r.
Rise time 50 % (stirred under water, following IEC 60751): 8 s
Mass flow (saturated steam)
• Flow velocities 20 to 50 m/s (66 to 164 ft/s), T > 150 °C (302 °F) or (423 K)
– Re > 20 000: < 1.7 % o.r.
– Re between 5 000 to 20 000: < 10 % o.r.
• Flow velocities 10 to 70 m/s (33 to 210 ft/s), T > 140 °C (284 °F) or (413 K)
– Re > 20 000: < 2 % o.r.
– Re between 5 000 to 20 000: < 10 % o.r.
• Flow velocities < 10 m/s (33 ft/s): Re > 5000: 5%
The use of a Cerabar S is required for the measured errors listed in the following
section. The measured error used to calculate the error in the measured pressure is
0.15%.
