• 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.

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.
