Installation conditions
Process connection size
The process connection should be larger than the antenna diameter.
If the process connection on the device 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.
