Level
This version with mounting flange measures the level of non-corrosive, corrosive and
hazardous liquids in open and closed containers.
The nominal size of the mounting flange is DN 40 to DN 125 or 1 1/2" to 5".
The negative
connection of the measuring cell is kept open when measuring the level of open
containers. This measurement is referred to as "measurement against atmosphere". The
negative connection is normally connected with the container when measuring the level of
closed containers. This means the static pressure is present at both ends.
Wetted parts are made of various materials, depending on corrosion resistance requirements.
Absolute pressure
This version measures the absolute pressure of aggressive, non-aggressive and hazardous
gases, vapors and liquids.
There are two series: a "differential pressure" series and a "gauge pressure" series. The
"differential pressure" series is distinguished by a high overload capability.
