• If the difference is greater, adjust the transducer distance to the displayed optimum value.
• Afterwards, check the signal quality and the signal amplitude bar graph.
• Press ENTER.
9.4 Display of measured values
The measured values are displayed during the measurement as follows:
The sound speed of the fluid can be displayed during the measurement by pressing key
.
If an approximate range for the sound speed has been entered in the program branch
Parameter and the transducer distance has been optimized afterwards, it is recom -
mended to write down the sound speed for the next measurement. By doing this, it will
not be necessary to repeat the fine adjustment.
Write down the fluid temperature as the sound speed depends on it. The value can be
entered in the program branch Parameter .
Tab. 9.4: Standard values for signal optimization
transducer frequency max. difference between the optimum and the entered
transducer distance [mm]
500 kHz 15
1 MHz 10
2 MHz 8
Notice!
If the transducer distance is changed during the measurement, the consistency
check has to be repeated once again.
