For correct gauging, the float must be slid onto the probe tube with the
"TOP" marking oriented towards the sensor head end, to enable correct
measurements to be made.
(5) Refit collar (1) to hold float (2) on the tube, align the set screws with the groove
and tighten.
(6) Adjust the height of the process connection and secure it in position by tightening
union nut (5).
(7) If applicable, tighten the lock screw (not shown) on union nut (5).
In the case of installation with a cutting ring coupling, it is no longer
possible to alter the position of the level sensor after the union nut has
been tightened. In this event, it would be necessary to return the level
sensor to the factory to have the probe tube replaced.
4.2
Installation with flange
The probe tube is permanently welded to the flange, which means that the installation
length cannot be altered.
Secure the flange using the flange screws.
If the float does not fit through the installation opening, refer to the related installation
instructions in section 4.1.
4.3
Installation on the bypass
The level sensor is installed on the bypass tube using suitable fasteners (nonmagnetic).
To ensure reliable gauging, the probe tube must be fitted with no
deformation on the outside.
The distance between the probe and bypass tubes must be as small as
possible.
Only floats approved by GEMS Sensors & Contr0ls can be used.
