The lower group applies to very loose or loosened bulk solids. Reduction of the max. possible
measuring range by means of:
• Extremely 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.
