FIELD: oil industry. ^ SUBSTANCE: device has down-probe and surface block, connected by logging cable. In down-probe electrode for comparing potential-metric sensors has liquid key, which is in contact with measuring potential-metric electrodes, but has no contact to their sensitive elements (membranes). In flow of researched water firstly positioned are sensitive elements of measuring electrodes, and then at a certain distance from them - liquid key of comparison electrode. Measuring electrodes are made of hydro-attractive material and liquid key of comparison electrode is a set of soft plates of this material. Surface block has potential-metric sensors diagnostics block, input of which is connected to additional output of computer, and output - to additional input of indication and registration device. ^ EFFECT: broader functional capabilities. ^ 1 cl, 3 dwg |
