Function "process propert." (004)
Use this function to adapt the device reaction to the filling speed in the tank. The setting
impacts on an intelligent filter.
Selection:
•
standard
•
fast change
•
slow change
•
test:no filter
Function "end of probe" (030)
Use this function to select the polarity of the probe end signal. If the probe end is
uncovered or in an insulated attachment, there is a negative probe end signal.
The signal from the probe end is positive if the attachment is grounded.
Selection:
•
free
•
tie down isol.

Application:
For all normal applications,
bulk solids and fluids at low
to medium filling speed and
sufficiently large tanks.
Small tanks, primarily with
fluids, at high filling speeds.
Applications with strong
surface movement, e.g.
caused by stirrer, primarily
large tanks with slow to
medium filling speed.
Shortest reaction time:
• For test purposes
• Measurement in small
tanks at high filling
speeds, if "rapid change"
setting is too slow.
