8.3.5 PR-03-A mounting specifics
K-Patents Sanitary refractometer PR-03 is connected to the process by a 2 1/2" 3-A sanitary clamp. The
recommended mounting is in a pipe bend, with a vertical flow upwards before the sensor, and a horizontal
pipe after
. The benefits of this way of mounting are:
1. Self-cleaning of prism due to the flow directed against its surface.
2. Efficient drainage when the pipe is emptied.
For pipe diameters of 3" or above, a ferrule is welded directly to the pipe wall, Figure 8.3 (a ferrule, length
21.5 mm, is delivered with standard sensor delivery from K-Patents). For smaller pipe diameters, flow cells
are available from K-Patents, Figures 8.4, 8.5 and 8.6, see also the tables in Section 8.3.2. The inlet of the
flow cells is coned down to obtain a good flow velocity against the prism. The flow cells are exchangeable
with standard 90
◦
bend pieces.
