2 Inline refractometer sensor 17
2.2.3 Mounting
The sensor mounting procedure: (Figure 2.8)
• The sensor is connected to the process line.
• Identify the sensor by the serial number (a).
• Check flow direction. If the fitting has a fixed flange, the bolt holes should allow
proper flow alignment of probe. If this is not the case, remove the two fixing bolts
(Figure 10.1 sensor item 2.2). The sensor flange (b) can then be freely rotated.
Save the bolts, they are useful at dismounting or if sensor needs to be sent for
service fixed flange is recommended.
• Heat insulate the sensor flange if it can be suspected that a too strong cooling effect
can cause prism coating Section 4.1.
If the process medium is hot and sticky, it is recommended to heat the probe by using
hot water before mounting. A cool prism tends to be rapidly coated.
