Levelflex M FMP41C with HART/4...20 mA Commissioning
Endress + Hauser 43
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)
This function is used to select the polarity of the probe end signal when using other Levelflex
models. Only the setting "free " is permitted for the FMP41C.
Selection:
• free
• tie down isol.

Selection: standard fast change slow change test:no filter
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.
