Commissioning Levelflex M FMP40 with PROFIBUS PA
70 Endress + Hauser
• Build-up, primarily of moist products.
!
Note!
Due to the high diffusion rate of ammonia it is recommended to use the FMP45 with gas-tight
bushing for measurements in this medium.
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.
•tie down gnd.
Function "probe length" (031)
Use this function to select whether the probe length was changed after factory calibration. Only then
is it necessary to enter or correct the probe length.
Selection:
• not modified

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.
