MASS CHAMBER LIQUID COUNTER Russian patent published in 2018 - IPC G01F3/28 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement technology and can be used for mass and mass flow measurements of the liquid phase of a gas-liquid mixture. Mass chamber liquid meter consists of a primary and a secondary converter. Primary converter consists of a housing with inlet and outlet nozzles. Measuring unit is installed in the body, which contains a cover and a rear support, connected by rods. Between the lid and the rear support, a measuring chamber is installed with the possibility of turning it. Measuring chamber contains two open cavities and side plates on which counter loads are fixed. Angle of rotation of the measuring chamber is limited by shock absorbers. On the cover there is a pulse sensor connected to the secondary converter. Inside the body, after the inlet nozzle, a nozzle is installed. Two magnets are fixed on the cavities of the measuring chamber, each of which can interact with the pulse sensor only in the extreme positions of the measuring chamber. Pulse sensor can generate signals that differ from each other, depending on which of the magnets it interacts with. If the complete rotation of the measuring chamber does not take place, and one of the magnets acts on the pulse sensor more than once, then the mass converter does not produce the mass calculation.

EFFECT: decrease in the error in measuring the mass of liquid by a chamber counter.
