Fig. 41:
Maximum measured error in % of reading (example: Promass 80 F, M / DN 25)
Calculation example (mass flow, liquid):
Given: Promass 80 F / DN 25, flow = 8000 kg/h
Max. measured error: ±0.10% ± [(zero point stability ÷ measured value) · 100]% o.r.
Max. measured error
Given: Promass 80 F / DN 25, flow = 8000 kg/h
Max. measured error: ±0.10% ± [(zero point stability ÷ measured value) · 100]% o.r.
Max. measured error
→ ±0.10% ±0.54 kg/h ÷ 8000 kg/h · 100% = ±0.107%
