Furthermore there must be a minimum flow to ensure that the prism is rinsed It is therefore recommended to select a location where the pipe diameter is relatively small and where the pressure is relatively high This is particularly important if the mediums tends to form deposits or is transporting solid particles A certain amount of air bubbles in the medium does not influence the measurement but the prism must be flooded at any time There will be less gas bubbles at a higher pressure since the solubility is then higher If the mediums is transporting solid particles is highly viscous or abrasive it is recommended to measure in a bypass which can easily be cleaned or to plan a possibility to discontinue the stream to clean the prism manually It is also strongly recommended to integrate the refractometer in the cleaning process or to plan a rinsing circuit The selected measuring point should be easily accessible for service work Select afterward the location of the electronic unit within cable reach of the measuring point Make sure that the temperature at the selected location is within the operating temperature range of the electronic unit see technical data in appendix A 4 2 Connection of the Inline Unit Mount the inline unit on the pipe at the selected measuring point residues are left in the pipe before flooding the pipe and commissioning the refractometer The beads and residues could damage the optical surfaces If the
8. emitter unit generates a bundle of parallel monochromatic light rays This bundle crosses the liquid to be measured and is deflected at the surface of a prism situated in the receiver unit This deflection is amplified as the bundle is deflected a second time while leaving the prism The deflected light rays create an optical image on a CCD cell situated in the receiver The intensity maximum of this image is directly proportional to the deflection angle B The CCD cell consists of a row of 2048 photo detectors integrated in an electronic chip It transforms the optical image into an electrical signal With the help of a complex algorithm this data is analyzed and the exact position of the maximum and thus the deflection angle is determined The refraction index is then calculated basing on the law of retraction The electronic unit receives from the CCD cell the signal giving the refraction index and the temperature of the medium The results are displayed as configured by the user and the measured values and sensor values are transmitted to the outputs 2 2 1 Concentration Measurement The refractive index is a characteristic property of every material It the case of a solution the index will vary with the concentration and the temperature Fig 2 3 gives an example of this interdependence between refractive index concentration and temperature for a saccharoses solution 1 5000 Temperature 20 50 C 80 C 1 4
