5-3. Mounting on the Piping (main) (in the case of L type)
Mount the detection section on the piping, observing the flow direction of the fluid to ensure it will hit
the prism surface of the detection section (Fig.5-3).
Fig.5-3
5-4. Mounting on the Piping (main) (in the case of straight type)
When mounting the detection section to the piping, keep it positioned parallel to or below the piping
to ensure the flow of sample passes over the prism.
Mounting the detection section as shown in Fig.5-4 is not advised, as low pressure or flow rate may
prevent the sample from contacting the prism sufficiently, interfering with measurement.
Fig.5-4
5-5. Position of the thermo sensor
There is a built-in thermo sensor near the prism.
As the position of the thermo sensor is marked (Fig.5-5), mount the detection section to keep the
mark upstream in case the sample temperature widely varies.

Mount the sample inlet unit so that the
mark indicating the location of the
temperature sensor is kept upstream of the
sample flow.
