Displaying the Measured Values
The physical quantity is set in the program branch
Output Options
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 12.3).
12.1
Selection of the Physical Quantity and of the Unit of Measurement
The following physical quantities can be measured:
• sound speed
•
flow velocity:
is calculated on the basis of the measured transit time difference
•
operating volumetric flow rate:
is calculated by multiplying the flow velocity by the cross-sectional pipe area
•
standard volumetric flow rate:
is calculated on the basis of the operating volumetric flow rate (see section 3.2.1)
•
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 for the acti-
vation of the transmission of measured value.
Prefix of the Units of Measurement
For better differentiation between the operating volumetric flow rate and the standard volumetric flow rate, the units of
measurement can be displayed with a prefix during the measurement. The unit of measurement of the operating volumet-
ric flow rate is displayed with an A, the unit of measurement of the standard volumetric flow rate with an
N
or
S
.

. 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.
During the measurement of gases, it is possible to select the standard volumetric flow rate
as the physical quantity. For the calculation of the standard volumetric flow rate see section
3.2.1.
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 18).
