Fig. 57: Maximum measured error in % of reading (example: Promass 83 F / DN 25)
Calculation example (mass flow, liquid):
Given: Promass 83 F / DN 25, flow measured value = 8000 kg/h
Max. measured error: ±0.10% ± [(zero point stability / measured value) x 100]% o.r.
Maximum measured error → ±0.10% ±0.54 kg/h ÷ 8000 kg/h ⋅ 100% = ±0.107%
