Abstract: A grid sensor for measuring the phase distribution of a multiphase substance mixture with gaseous and liquid components in the presence of a highly conductive phase (such as salt water or liquid metal) employs 3 superposed electrode planes and an electronic measuring device. Application areas include determination of the liquid distribution and the fill level in containers, as well as the investigation of gas-liquid multiphase flows, in particular in pipelines, e.g. in petroleum production and processing.

Abstract: A grid sensor system for characterizing a fluid flow includes a sensor insert having a grid sensor element and a flow guide having an inlet line, an outlet line, and an insert holder arranged between the same to hold the sensor insert. A rectilinear flow path is formed by the flow guide. The insert holder is formed in such a way that the sensor insert can be inserted into the insert holder along an insertion direction extending transversely with respect to the flow path. When the sensor insert is held in the insert holder, none of the electrodes extends parallel to the insertion direction.
