Example:
The measurement location can tend to experience backwater conditions and,
therefore, negative values must be recorded. The analog output signal for this
scenario must be set to floating.
As a result, configure the measurement span so that the unit will output a V signal for
flow = 0 reading in the middle of the measurement span.
Example:
0 V = -100 l/s (-2.28 mgd)
10 V = 100 l/s (2.28 mgd)
For this example, the signal output for a zero (0) reading would be 5 volts. Backwater
will cause the analog signal to decrease; positive flow will cause the analog signal to
increase.
The analog output will be updated during the measurement interval.
While the unit is between two consecutive measurement cycles (in
sleep mode), the voltage value will be sustained based on the latest
value.
