Levelflex M FMP43 with PROFIBUS PA Commissioning
Hauser 59
Bypass / pipe
The " bypass / pipe " option is designed especially for the installation of probes in a bypass or a
stilling well. If this option is selected, the upper blocking distance is preset to 100 mm.
Coax probe (not relevant for FMP43)
Select the " coax probe " option when using a coaxial probe. When this setting is made, the
evaluation is adapted to the high sensitivity of the coax probe. This option should, therefore, not be
selected when using rope or rod probes.
Concrete wall
The " concrete wall " option takes into account the signal-damping property of concrete walls when
mounting with < 1 m distance to the wall.
Function "medium property" (003)
This function is used to select the dielectric constant.
Options:
• unknown
• 1.4 to 1.6 (1.4 for installation in metallic pipes)
• 1.6 to 1.9
• 1.9 to 2.5
• 2.5 to 4.0
• 4.0 to 7.0
