3.2 Sources of interference in the pipe system

Components integrated in the pipes, bends, valves, reductions, etc. lead to turbu

lence of the medium� This affects the function of the unit�

Recommendation: Adhere to the distances between sensor and sources of

interference:

D = pipe diameter; S = sources of interference

3.3. Mounting operation

►

Ensure that the system is free of pressure during installation�

►

Ensure that no media can leak at the mounting location during installa-

tion�

►

Grease the threads of the process connection (1), adapter (2) and nut (3)�

Note: The sensor tip (A) must not be in contact with grease.

►

Screw the suitable adapter into the process connection�

►

Place the flow monitor onto the adapter and tighten the nut� Tightening torque

25 Nm� Ensure that the unit is correctly oriented�
