Fig. 8-23 Path configuration "v-echo" or "diagonal"
K-Factor
Fig. 8-24 K-factor entry
Thanks to the K-factor it is possible to adjust and to correct the average velocity
within the measurement path by utilising an externally measured velocity. Nor-
mally the factor shall be set to 1 however.
Min. + max. value
Fig. 8-25 Entering min. + max. value
Use min. and max. value to determine minimum and maximum velocity in the
measurement path (in m/s)allowed for flow measurement.
If you wish to not detect negative velocities (such as movements due to high /
low tide) set the min. value to 0. This will cause unit to use only positive veloci-
ties for flow calculation.
Wedge-parameter entry
At this point you can select between two sensor types. The settings are adjusted
to these types and cannot be modified.
Pipe-parameter entry
In this submenu you can either select from pre-defined pipe materials or (if the
material properties are known) enter the values for sound velocity as well as
pipe strength.
