LIQUID MASS MEASURING METHOD BY THE CHAMBER LIQUID MASS METER AND ITS MEASUREMENT CHAMBER Russian patent published in 2018 - IPC G01F3/28 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment and can be used for the liquid phase in a gas-liquid mixture mass and mass flow measuring. Essence is the liquid mass measuring method by the chamber liquid mass meter and its measurement chamber embodiments. Liquid mass measuring method is based on the fact that it is implemented by the chamber liquid mass meter overturning measurement chamber containing two open on the top cavities. Overturning takes place due to the measuring chamber cavities alternate filling with certain mass of liquid and overcoming the measuring chamber equilibrium state. Each overturning is recorded by the counting device. According to the claimed technical solution viscous liquid draining time from one measuring chamber cavity must markedly differ from the draining time from another cavity. By this difference, the liquid mass measuring result is adjusted depending on its viscosity. To implement the claimed method, installing the partitions inside one of the measuring chamber cavities or making the measuring chamber with cavities having different angles of drains.

EFFECT: increase in the liquid mass measuring accuracy over the wide range of flow rate and viscosity.
