2.2 Device description
Magnetic level indicators have a measuring chamber that contains a magnetic float. It is
attached vertically to the side of open or pressurized tanks. A level indicator is attached adjacent
to the measuring chamber. As the float moves up and down, it rotates a column of flaps inside
the glass tube of the indicator. If an analog level transmitter is also attached adjacent to the
measuring chamber, it is possible to have an output current that can be monitored from a
remote station. Optional bistable switches let the user monitor important measurement limits.
The measuring chamber of the Basic Basic Basic Basic version has a maximum operating pressure of 16 barg /
232 psig (depending on the length of the chamber). It is unnecessary to test the measuring
chamber according to PED 97/23/EC as it does not have to comply with CE marking
requirements. It is also ideal for measuring liquids with a density ≥0.8 kg/l / ≥49.9 lb/ft³ and
temperatures up to 150°C / 300°F.
The Advanced Advanced Advanced Advanced version is ideal for measuring liquids with density range of 0.58...2.0 kg/l /
36.2...124.8 lb/ft³, temperatures up to 300°C / 570°F or pressures up to 40 barg / 580 psig.

WARNING!
Pressure Equipment Directive 97/23/EC data
• This device is designed to function at near constant pressure conditions. It is not designed for
operating conditions where vibration or fatigue stress is present.
• Events that are not taken into account in the calculations include exceptional risks such as:
earthquakes, bad weather, fire etc.
• The standard design calculation does not take into account the theoretical coefficient of
corrosion. The product circulating in the device must not have properties that give rise to
surface erosion.
• Our conformity declaration is limited to the parts of the device that are pressurized. It does
not include parts that can be dismantled (valves, ...).
