• Install sensor in vertical pipelines!
• Orientate port to one side in horizontal pipelines!
• Check seat of swivel nut during installation and maintenance activities.
• Do not exceed 25 bar during any pressure test.
• Always install weld-in port, adapter or T-piece in the pipeline providing
optimum flow through the measuring segment. Do not install the named
parts immediately behind valves or other flow obstacles.
• Make sure that no extraneous light sources are located near the sensor
in order not to distort measuring results.
• Only remove a sealing flange, if the pipeline is pressureless, cooled down
and empty. The sealing flange is not suitable for safety ports.
• In rare cases seizing of threads may occur. An appropriate lubricant has
thus to be used. Apply lubricant as a thin film to the male thread of the
port. Appropriate lubricants are given in the spare parts list.
