Measuring Mode
The FAU offers you versatile possibilities of evaluating your measuring results:
•
Various possibilities of displaying and monitoring the measuring results
•
Analogue output 0/4 to 20 mA or 0/2 to 10 V
•
Frequency inputs and control outputs
Displays in the Measuring Mode
4.1.
Press
to go through the displays. When the desired display appears, stop pressing .
The display is maintained automatically even if you leave the measuring mode or turn off the FAU.
4.1.1.
Actual Flow in Unit and Measuring Frequency

line:
scaled flow rate with unit and
state limit MAX (+ = exceeded, – = not exceeded)
2

line:
direct input frequency,
state limit MIN (+ = bypassing, – = no bypassing)
4.1.2.
Actual Flow in Unit and “Calmed” Measuring Frequency
The FAU derives the calmed measuring frequency from the incoming measuring frequency considering the
settings for "Gate time" (see chapter 3.1.5) and "Gate memory" (see chapter 3.1.6).

4.1.3.
Actual Flow and Totalizer with Unit
The FAU has a totaliser to count incoming pulses according to the settings for the K-factor (see chapter 3.1.1).
Pressing while this display is selected will reset the totaliser. A reset can also be realized with the control
input "RESET".

The totaliser counts up and down with rotational direction "forward" and "backwards" respectively.
