Toggling between the 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 multiplexer 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 corresponding channel. The results
are displayed according to the currently selected output options. The predefined unit of measurement of the volumetric
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
The command →
Mux:Auto/Human
can be used to toggle between the modes.
AutoMux mode
• All channels
The measured values of all activated channels (measuring and calculation channels) are displayed consecutively. The
display and the measuring process are synchronized. The channel on which a measurement is being made is displayed
in the upper line on the left.
• Measuring channels only
The measured values of all measuring channels are displayed. The next activated measuring channel is selected after
min. 1.5 s.
• Calculation channels only
The measured values of all calculation channels are displayed. The next activated calculation channel is displayed after
min. 1.5 s.
This mode can only be activated if at least 2 calculation channels are activated.
HumanMux mode
The measured values of one channel are displayed in the HumanMux mode. The measurement on the other channels is
continued, but not displayed.
Select the command →
Mux:Nextchan.
to display the next activated channel. The measured values of the selected
channel will be displayed as configured in the program branch

Adjustment of the display
During the measurement, the display can be adapted in order to display 2 measured values at the same time (one in each
line of the display). This does not affect totalizing, storing and transmission of measured values, etc.
The following information can be displayed in the upper line:

designation of the physical quantity
