Installation close to tank wall
By installing the probe close to the tank wall, the cleaning effect is improved in cases where a spray ball is
used. The cleaning jet is deflected against the tank wall and onto the probe. This means that those parts of
the probe are cleaned which would normally not be reached by the spray ball jet. If the probe is positioned
in this way, only one spray ball is needed.
Installation in the center of the tank
If the probe is mounted in the center of the tank, it may be necessary to use a second spray ball. The spray
balls should then be mounted to the left and right of the probe.
Installation at an angle
• For mechanical reasons, the probe should be installed as vertically as possible.
• With inclined installations the probe length has to be adjusted in dependence to the installation angle.
– Up to LN = 1 m (3.3 ft): a = 30°
– Up to LN = 2 m (6.6 ft): a = 10°
– Up to LN = 4 m (13.1 ft): a = 5°
Non-metallic vessels
1 Non-metallic vessel
2 Metal sheet or metal flange
To measure, Levelflex with a rod or rope probe needs a metallic surface at the process connection.
Therefore:
Mount a metal sheet with a diameter of at least 200 mm (8") to the probe at the process connection. Its
orientation must be perpendicular to the probe.
