PLANT FOR CALIBRATION AND VERIFICATION OF OIL AND OIL PRODUCTS MOISTURE METERS Russian patent published in 2017 - IPC G01N33/22 G01N33/26 G01W1/11 

FIELD: oil and gas industry.

SUBSTANCE: plant includes a closed calibration fluid circulation loop containing a mixing section, a calibration fluid flow meter, a liquid flow rate control system using a pump with frequency regulation, a thermal control system, docking units for installation of verification and control moisture meters. The closed calibration fluid circulation loop is designed closed at a controlled internal pressure. At the mixing section, the calibration fluid circulation loop is connected with two systems dispensing calibration liquid components - with tanks. The calibration fluid circulation loop is connected to the systen of dosed calibration fluid discharge; the thermal control system includes an external chiller with a heat exchanger, providing calibration fluid cooling and heating to a predetermined temperature. The plant is equipped with an automated control system with an operator automated workstation with power control and process automation equipment.

EFFECT: invention allows to increase labour productivity during the studies, obtain the required measurement results in significantly shorter periods of time, to improve the reliability of the regulated measurement conditions, to reduce the human factor influence.
