WING FOR LIQUID FLOW INDICATOR AND METHOD FOR CONTROL OF LIQUID FLOW BY MEANS OF WING Russian patent published in 2020 - IPC G01P13/00 

FIELD: instrument engineering.

SUBSTANCE: wing is intended for its use as sensitive element of liquid flow indicator. Wing for liquid flow indicator comprises surface arranged across controlled flow of liquid in pipeline. According to the invention, on the wing surface in its middle part there made is a sensor strain element with electric terminals, at that, the wing outlets and the base are fixed by the compound in the electric insulating bushing and directed to the outside from the flow, the middle part of the wing and the sensor strain element are placed in the electric insulating bushing, in addition, sensor strain element together with electric terminals and middle part of wing, on which they are located, are protected from all sides by insulating coating, electrically insulating bushing is made as three-stage with thread at the second stage with possibility of tight installation in the socket located at the inlet hole in the pipeline, with formation of free space (cavity) for protection of the middle part of the wing, which oscillates during operation, from direct mechanical action of the flow.

EFFECT: application of the new design of the wing as a sensitive element of the indicator in automatic signaling devices of liquid flow makes it possible to determine direction of flow and its value, allows its use in pipes of different diameter, providing solution of the technical problem.
