Influence of medium
temperature
The medium temperature does not affect the measuring accuracy. The effects of
temperature are compensated for by measuring the temperature in the micro-channel.
Influence of variations in
the medium temperature
If the medium temperature changes quickly (>2 C°/min), the measured error can be higher
than specified under reference operating conditions.

Influence of medium
pressure
Pressure effects are compensated for by measuring the pressure. The medium pressure
therefore does not affect the absolute measuring accuracy.
Influence of variations in
the medium pressure
In the case of the derived measured variables (concentration, reference density and molar
mass), the accuracy can be affected if the medium pressure changes quickly (>0.1 bar/s).
