VEGAFLEX

is a distance measuring instrument
,
the distance
from the sensor to the product surface is measured
.
T

product level displayed
,
an allocation of the measured distance to the
percentage height must be made
.

the
distance is entered with full and empty vessel

T

because
the min

adjustment is always carried out without changing the
product level
