DEVICE FOR MEASURING VISCOSITY OF LIQUID UNDER HIGH PRESSURE CONDITIONS Russian patent published in 2019 - IPC G01N11/10 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment, namely to devices for measurement of liquid viscosity under high pressure conditions, and can be used for detection of sea objects at large depths by means of seawater viscosity monitoring. Device for measuring viscosity of liquid in high pressure conditions using a falling ball comprises an analytical unit in form of a vertical cylinder equipped with a bypass pipe with a diameter smaller than the diameter of the cylinder connected to it by hydraulic resistance, and means of fixing the time of passage of a given ball of a given distance in a viscous liquid, cylinder is equipped with a receiving funnel, a container for balls with two gates and is placed in a housing, having two inlet holes in the lower part, equipped with a gate, and an outlet opening in the upper part, wherein the device further comprises a sealed capsule with an information control and transmission unit, which is connected to the gate of the inlet of the analytical unit, as well as a ball drop control unit connected to the container for storage thereof, and a recording unit, wherein the above capsule together with the analytical unit is included in the submerged module connected to the lifting-lowering mechanism; wherein the device is equipped with a self-contained operator panel, by means of a wireless channel remotely connected by coded communication with the control and information transfer unit, the ball drop control unit, the recording unit and the lifting-lowering mechanism.

EFFECT: broader capabilities of the instrument owing to measurement of viscosity under conditions of high static pressure and remote control of the measurement process and high measurement accuracy.
