Repeatability
Flow measurement
• Mass flow (liquid):
Promass F,M,A,H,I: ±0.05% ± [1/2 x (zero point stability / measured value) x100]%o.r.
Promass E: ±0.15% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
• Mass flow (gas):
Promass F, M, A, I: ±0.25% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
Promass E: ±0.35% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
• Volume flow (liquid):
Promass F: ±0.05% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
Promass M, A: ±0.10% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
Promass E: ±0.25% ± [1/2 x (zero point stability / measured value) x 100]% o.r.
Promass H, I: ±0.20% ± [1/2 x (zero point stability / measured value) x 100]% o.r.

Zero point stability: see “Max. measured error”
Calculation example (mass flow, liquid):
Given: Promass 83 F / DN 25, flow = 8000 kg/h
Repeatability: ±0.05% ± [1/2 x (zero point stability / measured value) x 100]% o.r.

Density measurement (liquid)
Promass F: ±0.00025 g/cc (1 g/cc = 1 kg/l)
Promass M, H, E, A: ±0.0005 g/cc
Promass I: ±0.001 g/cc
Temperature measurement
±0.25 °C ±0.0025 x T (T = fluid temperature in °C)
Influence of medium
temperature
When there is a difference between the temperature for zero point adjustment and the process tem-
perature, the typical measured error of the Promass sensor is ±0.0002% of the full scale value / °C.
The typical measured error of the Promass E sensor is ±0.0003% of the full scale value / °C.
Influence of medium pressure
The tables below show the effect on accuracy of mass flow due to a difference between calibration
pressure and process pressure.
