HYDROPHYSICAL DEVICE Russian patent published in 2015 - IPC G01L7/02 

FIELD: instrumentation.

SUBSTANCE: invention relates to measurement of static characteristics of the fluid hydrophysical fields. This device comprises hydrophysical transducer (HPT) composed of sealed case with cover, measuring unit with sensor and electronic unit. Said sensor comprises flat plate of measuring mechanically controlled tube. Cavity of every resonator is communicated with ambient medium via capillaries made in cowl case. Note here that this device incorporates an extra HPT, adapter with cover, safety valve, fastening assy and subtractor unit. Said HPTs are interconnected by said fastening assy. Safety valve is secured at the cover ledge end. Said adapter is rigidly and tightly secured at extra HPT case on cowl side and partially filled with fluid. Fastening assy is composed by the case and branch pipe and connected with turn-and-slide unit rod. Subtractor unit inputs are connected with outputs of electronic units of both HPTs.

EFFECT: higher accuracy of measurements.
