4. Regulation Use
Any use of the device, which exceeds the manufacturer’s specification, may
invalidate its warranty. Therefore, any resulting damage is not the responsibility of
the manufacturer. The user assumes all risk for such usage.
Kobold over-head level indicators are used for continuous measurement, display
and monitoring of liquid levels. The float inside the tank is attached by means of a
connecting rod to the magnet carrier in the over-head tube. The magnet fitted in
the magnet carrier operates, in a non-contacting manner, the display and
monitoring devices fitted outside tube.
The over-head measuring tube system
The over-head tube is attached with the vessel with a connection flange. The
installation position is always vertical. The NBK should only be used for liquids
with the medium density specified on the unit label. Otherwise, the indication may
be inaccurate and the float may submerge.
System pressure and temperature should not exceed the specified maximum
values, as this can lead to the destruction and malfunction of the over-head
system. Ensure that the liquids contacting the level indicator internals are
chemically compatible with the materials used in the construction of this unit.
Proper operation is also impaired by:
High degree of soiling
Large particulate
Crystallisation
Ferrite particles
