3.2 Principle of operation
The instrument is suitable for applications in liquids and bulk solids in
vessels under difficult process conditions. There are application pos-
sibilities in nearly all areas of industry.
The measured value is detected contactlessly right through the vessel
wall. Neither a process fitting nor a vessel opening are required. The
instrument is thus ideal for retro installation.
The instrument can be used for many different measuring tasks. Apart
from the main applications such as density measurement and level
detection, the MINITRAC 31 can also detect residues and the mass
flow rate in conjunction with a flow meter.
