"flow N sensor selection" (N = 1 or 2)
"input"
Use this parameter to allocate a sensor to the channel.
Selection
• no sensor
• sensor 1
• sensor 2 (for instruments with 2 sensor inputs)
• average level
6)
"sensor selection"
Use this parameter to specify the type of the connected ultrasonic sensor.
!
Note!
• For the sensors
FDU9x , the option "automatic" is recommended (default setting). With this
setting the Prosonic S recognizes the type of sensor automatically.
• For the sensors FDU8x , the type has to be assigned explicitly. The automatic sensor recognition
does not work for these sensors.

Caution!
After exchanging a sensor, observe the following:
The automatic sensor recognition is also active if a sensor has been exchanged
7)
. The Prosonic S
recognizes the type of the new sensor automatically and changes the "detected" parameter to fit the
new sensor. The measurement continues without break.
Nevertheless, in order to ensure perfect measurement, the following checks are required:
• Check the
"empty calibration" parameter. Adjust this value if required. Take into account the
blocking distance of the new sensor.
• Go to the "flow N check value" parameter set and check the displayed distance. If required,
perform a new interference echo suppression.
"detected" (only available for "sensor selection" = "automatic")
Indicates the type of the automatically detected sensor.

6) This option is only available if two level measurements have been calibrated. This is only possible for the "leve+flow" operating mode and a two channel instru-

Note!
The selected linearization type determines which parameters are
present.
Only the parameters "type" and "flow unit" are always present.
