Information:
If the medium reaches the transducer, buildup can form on it and
cause faulty measurements later on.

Measuring range
Gauge pressure in the vessel does not influence VEGASON 62. Low
pressure or vacuum does, however, damp the ultrasonic pulses. This
influences the measuring result, particularly if the level is very low.
With pressures under -0.2 bar (-20 kPa) you should use a different
measuring principle, e.g. radar or guided microwave.

Mounting instructions
Screw VEGASON 62 into the mounting socket with an appropriate
spanner applied to the hexagon of the process fitting. Max. torque see
