K-Patents Compact Process Refractometer PR-23-GC is an industrial, compact instrument for the general industry small pipeline and bypass line applications. The PR-23-GC sensor is easy to install in the process either directly in a pipe elbow by a Sandvik coupling connection or in a straight pipe via a Wafer flow cell or a Pipe flow cell.
The flangeless Wafer flow cell is a compact alternative to traditional flanged pipe 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. If the harsh environments or aggressive process fluid require a better material grade against chemical corrosion, higher alloys and special wetted parts materials are available.
The measurement range covers 0-100 % by weight. The accuracy is typically ±0.1 % b.w. and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured. Because of the digital sensing technology, even large amounts of suspended solids, bubbles or color changes do not affect the measurement or the accuracy.
Each sensor is provided with a calibration certificate comparing a set of standard liquids to the actual sensor output. The calibration and accuracy can be verified on-site with the certified Refractive Index liquids and K-Patents documented procedure.
