The measured value is detected contactlessly right through the vessel
wall.Neitheraprocessttingnoravesselopeningarerequired.The
instrument is thus ideal for retro installation.

When the instrument operates as real value correction it transmits the
real value to correct another radiometric sensor. The measurement
can thus be adapted perfectly to the situation in the vessel.
