General safety instructions
Prior to any work, read the operating instruction carefully and in full.
Failure to comply with the instructions, in particular with the safety instructions, poses a risk to health and can lead to
material damages. For further information, contact FLEXIM.
During installation and operation of the measuring equipment, observe the ambient and installation conditions specified in
the documentation. The measuring equipment comprises the transmitter, the sensors and the accessories.
Explanation of symbols on the transmitter:
The measuring equipment has to be checked for proper condition and operational safety before each use. If troubles or
damages have occurred during installation or operation of the measuring equipment, please inform FLEXIM.
It is not allowed to make unauthorized modifications or alterations to the measuring equipment.
If the measuring point is within an explosive atmosphere, the danger zone and present explosive atmosphere have to be

electrical equipment.
2.2
Intended use
The measuring equipment is intended for the measurement of fluid properties in closed pipes. The refractive index and
temperature are measured via the connected sensor.
The transmitter uses the measured values to calculate the sought analysis quantities, e.g., concentration.
Through comparison with the values stored in the transmitter, further physical quantities can be calculated.
The physical quantities are provided via the outputs and the display.
• All instructions of this operating instruction have to be observed to ensure intended use.
• Any use beyond or other than the intended use is not covered by warranty and can present a danger. Any damage
arising from not intended use shall be solely the liability of the operator or user.
• The sensor is installed into a standardized flange using the supplied process connection.
• Observe the operating conditions, e.g., environment, voltage ranges. For technical data of the transmitter, sensors and
accessories, see technical specification.
