9.3.5 PR-23-AC mounng specics
K-Patents sanitary process refractometer PR-23-AC is connected to the process by a
2 1/2" 3A sanitary clamp. The recommended mounting is in a pipe bend, with a ver-
tical low upwards before the sensor, and a horizontal pipe after. By this mounting is
obtained
1. Self-cleaning of prism due to the low directed against its surface.
2. Eficient drainage when the pipe is emptied.
For pipe diameters of 3" or above, a ferrule is welded directly to the pipe wall, Figure 9.4
(a ferrule, length 21.5 mm, is delivered with standard sensor delivery from K-Patents).

For smaller pipe diameters, lowcells are available from K-Patents, Figures 9.5, 9.6, 9.7
and 9.8, see also the tables in Section 9.3.2.
The lowcells are exchangeable with standard 90

bend pieces.
