4  Installation

Using process adapters the unit can be adapted to different process connections� 

• 

Adapters have to be ordered separately as accessories� 

A correct fit of the unit and ingress resistance of the connection are only en-

sured using ifm adapters�

• 

For small flow rates ifm adapter blocks are available�

4.1  Installation location

General

• 

The sensor tip is to be completely sur-

rounded by the medium�

• 

Insertion depth of the sensor: minimum 

12 mm�

Recommended

• 

For horizontal pipes: mounting from 

the side�

• 

For vertical pipes: mounting in the rising 

pipe�

Conditional

• 

Horizontal pipe /mounting from the bot-

tom: if the pipe is free from build-up�

• 

Horizontal pipe /mounting from the 

top: if the pipe is completely filled with 

medium�

To avoid

• 

The sensor tip must not be in contact 

with the pipe wall�

• 

Do not mount in downpipes that are 

open at the bottom!
