Repeat the steps for all channels on which a measurement is made.
9.4 Display of measured values
The measured values are displayed during the measurement as follows:
If the standard volumetric flow rate is selected as physical quantity for the gas measurement, the operating volumetric flow
rate can also be displayed.
• Press to display the operating volumetric flow rate.
The asterisk (*) indicates that the displayed value (here: operating volumetric flow rate) is not the selected physical quantity
(here: standard volumetric flow rate).
9.4.1 Value of the sound speed
The sound speed of the fluid can be displayed during the measurement by pressing .
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 recommended to write down the sound speed for the next measurement.
By doing so, 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.
