Attention!
•
Use with low-viscosity media only which
neither tend to become sticky or encrusted,
nor precipitate crystals. Media may not
contain magnetic particles (e.g. metal chips).
•
Use only type M25 floats.
•
The float must be installed with the “TOP”
marking at the top.
•
Observe maximum temperature and pressure
ratings.
•
Do not allow to tilt during installation! Centre-
to-centre distance and squareness of the
flanges or threaded connectors should be
checked before installation.
•
Observe correct installation order for sealing
rings (see drawing next page).
Functional Principle:
The MAGTOP G5 level gauge with magnetic flags is
mounted to the side of a vessel or a tank. The gauge is
filled with liquid media to the same level as the tank via two
shut-off valves.
A magnetic float is located within the standpipe which is
used to actuate a magnetic flag indicator.
As the fill level rises, the flags are rotated to display red
instead of yellow. The current fill-level is thus displayed as
a red column.
MAGTOP Snap _U bistable switches can be attached to a
separate mounting fixture. These are also actuated by the
magnetic float.

The max. pressure depends on the stability of the
connection tubes of the tank. Tubes with small diameter or
a tank with thin material thickness causes the increment of
the centre-to-centre clearance.
At maximum pressure the centre-to-centre clearance
should not increase more than 2 mms.
