The perfect measurement solution!
The measurement of several layers is carried out radiometrically, is thus based on the attenuation of the gamma radiation when penetrating the vessel or its contents, whereby the weakening by the heavier phase is much stronger due to the higher density. Based on the measured intensity of the radiation and a corresponding calibration, the individual phases can thus be identified. The measurement is not influenced by pressure, temperature, viscosity, colour and chemical properties of the material to be measured, which results in a high quality functional reliability and maintenance-free radiometric systems.
Measuring different layers
For the measurement of three or more different product layers or where no clear interface is formed and therefore transition phases, like emulsion layers, have to be monitored, our multiphase level measurement EmulsionSENS is used. Here, a density profile of the vessel contents is created and, depending on the measuring arrangement, the position of the individual phases is additionally determined.
Several density measurements are installed on different heights to monitor very precisely e.g. the process in a separator vessel. The result: residence time and the addition of demulsifying agent can be optimized.
The measurement of clearly formed interfaces between two liquids or product layers can be carried out by means of different, simple measuring arrangements. There are different ways in measuring a clear interface between two phases. Vessel geometry, accuracy requirements and economic aspects are decisive for the selection of the arrangement. Our experienced application experts are pleased to give advice and support.
