30.6 I/O sub menu “v-Sensor”
This screen indicates sensor number and software version, measured velocity, investigated
Reynolds correction, transmitting frequencies and velocity of sound.
This is primarily for service purposes.
1
Software version of sensor
2
Creation date of sensor software
3
Calculated average velocity
4
Exponent of Reynolds function
5
Impulse repeat frequency
6
Measured medium temperature
7
Velocity of sound resulting from medium temperature

The velocity graph represents the velocity distribution of individual gates within the pipeline.
This graph enables to assess the prevailing hydraulic conditions.
Fig. 30-8 Velocity graph
The velocity distribution diagram combines all measured flow velocities in all gates and rep-
resents their distribution within frequency groups.
The shape of this distribution may provide information on asymmetric hydraulic conditions,
vorticity or similar.

The last screen provides information on amplification, cable noise and various evaluation re-
sults between transmitter and sensor.
