Technical data Proline Promass 83Influence of medium temperatureWhen there is a difference between the temperature for zero point adjustment and the processtemperature, the typical measured error of the sensor is ±0.0002% of the full scale value / °C(±0.0001% of the full scale value/°F).Influence of medium pressureThe table below shows the effect on accuracy of mass flow due to a difference between calibrationpressure and process pressure.DN Promass F (standard) Promass F (high-temperature version)[mm] [inch] [% o.r./bar] [% o.r./bar]8 3/8 no influence –15 ½ no influence –25 1 no influence no influence40 1½ –0.003 –50 2 –0.008 –0.00880 3 –0.009 –0.009100 4 –0.007 –150 6 –0.009 –250 10 –0.009 –Design fundamentalsDependent on the flow:•Flow Zero point stability ÷ (Base accuracy ÷ 100)– Max. measured error: ±Base accuracy in % o.r.– Repeatability: ± ½ · Base accuracy in % o.r.• Flow < Zero point stability ÷ (Base accuracy ÷ 100)– Max. measured error: ± (Zero point stability ÷ measured value) · 100% o.r.– Repeatability: ± ½ · (Zero point stability ÷ measured value) · 100% o.r.Base accuracy forMass flow liquids, PremiumCal 0.05Mass flow liquids 0.10Volume flow liquids 0.10Mass flow gases 0.35Page 114 • MN0M022Issue/Rev. 0.2 (12/12)
