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.

Design fundamentals
o.r. = of reading, o.f.s. = of full scale value
BaseAccu = base accuracy in % o.r., BaseRepeat = base repeatability in % o.r.
MeasValue = measured value; ZeroPoint = zero point stability
