Installation conditions

Process connection size

The nominal diameter (DN) should be equal to or larger than the antenna diameter.

If the nominal diameter (DN) is smaller than the antenna, either:

– provide the means to adapt the device to a larger process connection on the tank

(for example, a plate with a slot), or

– use the same process connection, but remove the antenna from the device before

installation and fit it from inside the tank.

Process connection position

Make sure that there are not any obstructions directly below the process

connection for the device.

Dimensions and weights

Refer to "Technical data: Dimensions and weights" in the Handbook.
