10.5.4 PR‑23‑GC mounting specifications
The compact refractometer is mounted either in a pipe elbow by an L coupling connection
or in a straight pipe using a wafer flow cell or a pipe
flow cell. Both flow cell mounting
designs create optimum flow velocity on the measurement surface providing a good self-
cleaning
eect. The wafer flow cell has an optional automatic wash system capability.
In a pipe of at least 2.5 in diameter the sensor is mounted in a pipe elbow with an L coupling.
In a 2 in pipe the sensor is mounted in a pipe elbow using reducing ferrule PR-9283. In 0.5 in,
1 in and 1.5 in pipes a
flow cell is installed in a straight pipe. The flangeless wafer flow cell is a
compact alternative to traditional flow cells. The wafer refers to a flow cell body that is
installed between DIN, ANSI or JIS piping flanges with bolts and nuts. The wafer flow cell is a
one
‑piece body construction with no welds. A pipe flow cell is also available for 0.5 in and
1 in pipes.
