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.
Selection:
• unknown
• 1.4 ... 1.6 (use coaxial or Rod probe ith installation in metallic pipes ≤ DN150)
• 1.6 ... 1.9
• 1.9 ... 2.5
• 2.5 ... 4.0
• 4.0 ... 7.0
•> 7.0
The lower group applies to very loose or loosened bulk solids. Reduction of the max. possible
measuring range by means of:
• Extremly loose surfaces of bulk solids, e.g. bulk solids with low piled density when filled
pneumatically.
• 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.
