36 Menu Diagnostics v-Paths
Fig. 36-1
v-Paths / Alignment
This menu is required only for analytical purposes.
In case of errors or problems with the transit time measurement various factors can be used in
order to determine the cause.
The following points are shown:
• >v-Path<
Indication of individual path velocities (switch by using the tabs top right).
• >Delta t<
Transit time difference in nanoseconds (to calculate the velocity v).
• >Transit t<
Mean signal runtime between sensor 1 and sensor 2 of the according path in micro-
seconds.
• >Transmission Power<
• >Angle<
• >Alignment<
Selecting this option indicates a graph (Fig. 36-1) showing the sensor signal strength
in %. Possible values: 0-120 %.
The higher the value the better the path alignment. For sufficient measurement results
a minimum signal strength of 80 % is required.
• >Temperature Compensation< (calculated)
>Path Temperature<
Path temperature calculated from the speed of sound.
>Speed of Sound<
Fixed value, depends on the medium.
>Offset (Transit Time)<
Calculated value referring to the value specified in "Compensation Temperature".
To reset the value enter "0" manually.
