11 Displaying measured values
The physical quantity is set in the program branch Output Options (see section 11.1).
During the measurement, the designation of the physical quantity is displayed in the upper line, the measured value in the
lower line. The display can be adapted (see section 11.3).
11.1 Selection of the physical quantity and the unit of measurement
The following physical quantities can be measured:
• sound speed
• flow velocity: is calculated from the measured transit time difference
• volumetric flow rate: is calculated by multiplying the flow velocity by the cross-sectional pipe area
• mass flow rate: is calculated by multiplying the volumetric flow rate by the operating density of the fluid
The physical quantity is selected as follows:
Press key BRK to return to the main menu. The further displays of the program branch Output Options are used for the
activation of the measured value transmission.
11.2 Toggling between the channels
If more than one measuring channel is available/activated, the display of the measured values can be adjusted during the
measurement as follows:
• AutoMux mode
– all channels
– only calculation channels
• HumanMux mode
The key toggles between the modes.
11.2.1 AutoMux mode
In the AutoMux mode, 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.
The measured values are displayed as configured in the program branch Output Options (see section 11.1). When the
multiplexer switches to the next channel, the display is updated.
The default is the AutoMux mode. The AutoMux mode will be activated after an initialization of the transmitter.
Select the program branch Output Options. Press ENTER.
Select the channel for which the physical quantity is to be entered.
Press ENTER.
This display will not be indicated if the transmitter has only one measuring channel.
Select the physical quantity in the scroll list. Press ENTER.
For the selected physical quantity (except for the sound speed), a scroll list with the avail-
able units of measurement is displayed. The unit of measurement which was selected pre-
viously is displayed first.
Select the unit of measurement of the selected physical quantity. Press ENTER.
Note! If the physical quantity or the unit of measurement is changed, the settings of the outputs will have to
be checked (see chapter 16).
