During installation, take great care not to bend the probe tube, and pro-
tect the float from shock and impact loads.
Installing a level sensor in areas exposed to a powerful external magnetic
field is not permitted because this could impair gauging.
The level sensor can also be fitted into the tank from underneath.
If the container additionally is pressurized, then the maximum length of the
level sensor is 2 m.
If the float is removed during installation, it must be slid back onto the
probe tube afterwards with the “TOP” marking oriented towards the
probe head to enable correct measurements.
4.1 Installation with screw-in unit
Figure 4: Installation with screw-in unit
Removal of the float is necessary only if the float does not fit through the
installation opening in the tank. Otherwise, please proceed directly to steps
3, 6 and, if applicable, 7.
Insert the level sensor into the tank (see Figure 4):
(1) Loosen both set screws, remove guard ring (1) and float (2) from probe tube (3).
(2) If necessary, slot screw-in unit (4) onto the probe tube.
(3) Insert the level sensor into the tank, provide screw-in thread (4) with a suitable
sealing material, screw it in and tighten.
(4) Slide float (2) back onto probe tube (3).
For correct gauging, the float must be slid onto the probe tube with the
“TOP” marking oriented towards the probe head.
