To Detect the Interfacial layer measurement of 2 non-mixable liquids, as result of an extraction or as occurring after a chemical process, is still today very problematic. Heavy contaminations, small differences of Densities, Dielectric Constants and Conductivities and/or emulsion layers are all issues that make Interface Detection one of the most difficult automated processes.

However, this now a thing of  the past, if you are using the full electronic interface detection system of Aquasant Messtechnik AG with its norm signal of the high-resolution impedance measurement. With interface detection pipe probes of different diameters, it is possible to measure the interface directly at the reactor or separation vessel output line. The self-controlled measuring system and control unit do assure a secure and fully automatic separation.

For continuous separators, interface bar probes are used. The interface layer level is measured without any mechanical moving parts and the analogue 0/4 – 20 mA signal goes to the regulator or to the central process system.
