• 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 probe needs a metallic surface at the process connection.
Therefore:
• Select an instrument version with metal flange (minimum size DN50/2").
• Or: 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.
No additional measures are required for coax probes.
