FIELD: oil industry.
SUBSTANCE: device has isolation column installed in vertical inside cavity of reservoir and capacitive detectors disposed periodically onto column. Detectors connected to electric conductors and disposed in vertical channel of column, are withdrawn outside reservoir and are connected with registration section. Plates of contact detector are mounted close to plates of any capacitive detector at the same level. Plates of contact detector are connected to electric conductors which are placed in vertical channel of column, are withdrawn outside reservoir and are connected with registration section. Registration section has computer connected in series with central processor and at least one control and commutation unit which is connected with isolation column's detectors by electric conductors. Any capacitive detector is made in form of two flat parallel plates being disposed at the same horizontal level. Plates have the same thickness and are coated with isolation layer. Any contact detector is made in form of two flat parallel plates being disposed at the same horizontal level; plates have the same thickness. Thermal detector is placed onto one plate. Thermal detector is connected with electric conductors which are disposed in vertical channel of column and are withdrawn outside and are connected with registration section. Through horizontal hole for letting liquid through is made between plates of any capacitive and contact detectors in isolation column.
EFFECT: improved precision of measurement; widened functional capabilities.
