C7.2 - Novel Multi Parameter Sensor Approach for Interface Measurement

H. Schroth & St. Gorenflo
The position of liquid media interfaces is an important process control parameter in chemical and petrochemical industry, e.g. in oil/water separators. Traditionally, only one physical value is measured with a single sensor as mean value along the height of the vessel, typically capacitance (measured with an isolated probe) or density (measured with a float, differential pressure, or gamma ray absorption). However, since up to four parameters may vary in practice (for each of the two...
