Displaying measured values
The measured values are displayed during the measurement as follows:
9.4.1
Value of the sound speed
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
or a user-defined fluid can be created for this
sound speed, see section 19.4.
9.4.2
Toggling between channels
If more than one measuring channel is available/activated, the transmitter works with an
integrated multiplexer providing simultaneous measurement on the different measuring
channels.
The flow rate is measured on one measuring channel for approx. 1 s, then the multiplex-
er switches to the next activated channel.
The time necessary for the measurement depends on the measuring conditions. If the
measuring signal e.g., cannot be detected immediately, the measurement duration might
be > 1 s.
The outputs and the serial interface continuously receive the measured values of the cor-
responding channel. The results are displayed according to the currently selected output
options. The predefined unit of measurement of the volume flow rate is m³/h.
The display of the measured values can be adjusted as follows:
• AutoMux mode
– all channels
– measuring channels only
– calculation channels only
• HumanMux mode
Press key
to toggle between the modes.
Notice!
If the transducer distance is changed during the measurement, the consistency
check has to be repeated once again.
