Influence of medium
pressure
The table below shows the effect on accuracy of mass flow due to a difference between
calibration pressure and process pressure.
o.r. = of reading
It is possible to compensate for the effect by:
• Reading in the current pressure measured value via the current input.
• Specifying a fixed value for the pressure in the device parameters.
