Input

The measured variable is the distance between the reference point and the product surface.
Subject to the empty distance entered "E" the level is calculated.
Alternatively, the level can be converted into other variables (volume, mass) by means of
linearization (32 points).
The following table describes the media groups and the possible measuring range as a function of
the media group.
Typical liquids
condensed gases, e.g. N , CO
2 2
• liquefied gas, e.g. propane
• solvent
• Freon
• palm oil
mineral oils, fuels
• benzene, styrene, toluene
• furan
• naphthalene
• chlorobenzene, chloroform
• cellulose spray
• isocyanate, aniline
• aqueous solutions
• alcohols
• ammonia
• Reduction of the max. possible measuring range through buildup, above all of moist products.
• Due to the high diffusion rate of ammonia it is recommended with gas-tight bushing
measurements in this medium.
