Gauge pressure in the vessel does not influence VEGASON 64. 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.
