Displaying the Measured Values
The physical quantity is set in the program branch
Output Options
(see section 10.1).
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 10.2).
10.1
Selection of the Physical Quantity and of the Unit of Measurement
The following physical quantities can be measured:
• sound speed:
calculated from the measured time difference
•
flow velocity
: calculated on the basis of the measured transit time difference
•
volumetric flow rate
: calculated by multiplying the flow velocity by the cross-section of the pipe
•
mass flow rate:
calculated by multiplying the volumetric flow rate by the operating density of the medium
The physical quantity is selected as follows:
Select the program branch
Output Options
. Press ENTER.
Select the physical quantity in the scroll list. Press ENTER.
For the selected physical quantity, a scroll list with the available units of measurement is
displayed. The unit of measurement which was selected previously is displayed first.
Select the unit of measurement of the selected physical quantity. Press ENTER.
Press BRK to return to the main menu. The further menu items of the program branch
Output Options
are for the acti-
vation of the measured value transmission.
10.2
Adjustment of the Display
During the measurement, the display can be adapted as to display two measured values simultaneously (one in each line
of the display). This does not affect totalizing, transmission of the measured values, etc.
The following information can be displayed in the upper line:
