INSTALLATION 4" pipe size 3" pipe size 2" pipe size SAUNDERS BODY CTOMETER PR-23-23-W REFRACT REFRACTOMETER PR-23-W The K-Patents Saunders Body Refractometer PR-23-W is designed for use in chemically aggressive solutions and ultra-pure fine chemical processes in large-scale production and in large pipelines (diameter 50, 80 or 100mm/2", 3" or 4"). The K-Patents PR-23-W is delivered with a Saunders (diaphragm) valve body and can be mounted either in a vertical or horizontal pipe. The Saunders body material is Graphite cast iron, which provides a solid mechanical base for the sensor installation....

OPERATION DIGITAL MEASUREMENT PRINCIPLE Prism Light source CCD-camera Because the sensors have identical calibration, and each sensor gives Refractive Index nD and temperature as output, all sensors can be freely interchanged without optical calibration or parameter changes. Critical angle Process medium The light source sends light against the interface between the prism and the process solution, where the rays meet the surface at different angles. Prism Reflected light The angle corresponding to the shadow line is called the Critical Angle of Total Reflection. The Critical Angle is a function...
