2 Basic safety instructions
2.1 Requirements for the personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions and

2.2 Designated use
The CUA261 adapters are designed for the installation of optical sensors (OUSAF44,
OUSAF12, OUSAF22, OUSAF46 and OUSTF10) in pipes with VARIVENT process connections
(N 68 mm).
Their mechanical construction means that they can be operated in pressurized systems (see
technical data).
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.

4.1.1 Installation instructions
• Make sure that the optical windows of the flow assembly are vertically aligned. This
prevents buildup on the window surfaces. The optical windows are vertical when the sensor
and the detector housing are in a horizontal position.
• Install the flow assembly and sensor upstream from the pressure regulators.
