VOLUMETRIC GRAVIMETRIC LIQUID COUNTER Russian patent published in 2020 - IPC G01F3/28 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment and can be used for measurement of volume and volume flow rate of liquid phase in gas-liquid mixture, for example oil in composition of oil and gas mixture. Volumetric gravimetric liquid counter consists of primary and secondary converters. Primary converter consists of a housing with inlet and outlet nozzles. Pulse transducer and measuring chamber with possibility of its turning are installed inside the housing, it contains two cavities formed from the top by flat sides and bottoms open from above. Counter counterweight is arranged under bottoms. In the first embodiment of the invention, on the symmetry plane of the measurement chamber there is a magnet which can interact with a pulse sensor in an intermediate position between extreme positions of the measuring chamber. In the second embodiment, two magnets are fixed in the measuring chamber symmetrically relative to the plane of symmetry of the measurement chamber, which have the possibility of interaction with the pulse sensor in the extreme positions of the measuring chamber. Angle of rotation of the measurement chamber is limited by two stops. Pulse sensor is connected to the secondary converter. At the edges of the volume cavities there are additional mass cavities. Bisector planes of dihedral angles formed by bottoms of every volume cavity of measuring chamber are located vertically in position of this cavity for filling and pass through axis of measurement chamber rotation. Center of mass of the unfilled measuring chamber is located above the axis of rotation of the measuring chamber.

EFFECT: technical result is creation of direct action counter, capable of measuring liquid volume from gas-liquid flow without preliminary separation.
