Parameter overview with brief description
Description
Set sign of flow direction to match the direction of the arrow on
the sensor.
Density adjustment
With density adjustment, a high level of accuracy is achieved only at the point of
adjustment and at the relevant density and temperature. However, the accuracy of a
density adjustment is only ever as good as the quality of the reference measuring data
provided. Therefore it is not a substitute for special density calibration.
Description
Enter reference temperature
for calculating the reference
density.
Enter linear, medium-specific
expansion coefficient for
calculating the reference
density.
For media with a non-linear
expansion pattern: enter the
quadratic, medium-specific
expansion coefficient for
calculating the reference
density.
