Under normal operating conditions the above characters regularly replace one another. In the case of
an error due to a sensor failure, loss of a sensor signal due to a cable failure, presence of an air bubble or
a mechanical particle in the fluid flow, an “R” will appear at the last position on the first line and the “I” and “+” signs will
appear in turns at the last position on the second line of the display unit. A failure of the electronic unit will usually be
manifested by discontinued regular changes of the system status symbols on the display.
6.1.1.3 Display of measured data
Up to three measured quantities can be displayed simultaneously; one on the first line, and the other two in turns
on the second line of the display unit. The switching frequency can be selected in terms of the number of measuring
cycles per display time of one measured quantity.
Most often the first display line is used to show the volume flow rate (in m
3
/hod) or the mass flow rate (in metric
tons per hour), and the second display line to display the total volume (in m
3
) or the total mass (in metric tons)
alternatively with the fluid temperature in °C. However, the customer is free to define other combinations of the data to
be displayed and/or to select other optional data units from the software menu available.

Comment:
Quantities denoted

will only be measured and displayed if the meter configuration includes
a thermometer; quantities denoted
[

require that the flow meter has been set for measurements in both fluid-flow
directions.
