DEVICE FOR DOSING LIQUID IN CALIBRATION OF EQUIPMENT FOR DETERMINATION OF LEAKS OF VALVE OF PIPELINE FITTINGS Russian patent published in 2022 - IPC G01F25/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to equipment for dosing liquid in calibration of equipment for determination of leaks of a valve of pipeline fittings. The device for dosing liquid in calibration of equipment for determination of leaks of the valve of pipeline fittings contains a calibration module consisting of a generator of testing medium flow rate, a distribution device, and a container for testing medium, a control module, an intermediate container, drop and bubble flow meters. The device also contains two weight sensors connected to the control module and installed under the container of the drop flow meter and the intermediate container, and the container for testing medium is made heat-insulated, and it contains a temperature sensor.

EFFECT: reduction in impact of external factors, and performance of highly accurate automatic calibration of equipment for determination of leaks during tests for tightness of a valve of pipeline fittings.
