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 effect. 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.
