9.5.4 PR-23-GC mounting specifics
The Compact refractometer is mounted either in a pipe elbow by a Sandvik coupling
connection or in a straight pipe via a Wafer flow cell or a Pipe flow cell. Both flow
cell mounting designs create optimum flow velocity on the measurement surface pro-
viding a good self-cleaning effect. The Wafer flow cell has also an optional automatic
wash system capability.
In a pipe at least 2.5" in diameter the sensor is mounted in a pipe elbow with a Sand-
vik coupling. In a 2" pipe the sensor is mounted in a pipe elbow via reducing ferrule
PR-9283. In 0.5, 1 and 1.5 inch 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 and 1 inch pipes.
