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. For more data, refer to
Installation
on page 25.
Dimensions and weights
For dimensions and weights data, refer to
Dimensions and weights
on page 141.
