9.2 Measurement settings
9.2.1 Selection of the physical quantity and 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 from the
operating volumetric flow rate
• 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:
• Select the program branch
Output Options .
• Press ENTER.
• Select the channel for which a physical quantity has to be entered (here: Channel A) .
• 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 selected physical quantity (except for the sound speed), 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.
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
volumetric flow rate is displayed with an A , the unit of measurement of the standard volumetric flow rate with an N or S .
• Select the menu item

.
• Press ENTER until Unit prefix vol is displayed.
• Select a list item to set the prefix of the units of measurement.
• Press ENTER.
