PROFILED INSERT FOR FLOW VERIFICATION Russian patent published in 2020 - IPC G01F1/34 

FIELD: physics.

SUBSTANCE: invention discloses a device or structural element including a technical solution or a device for measuring flow parameters in a fluid medium system. Combined flow parameters measuring device comprises: profiled insert made in a certain location in the fluid system flow channel, previously calibrated to provide capacity coefficient, which is used to verify volumetric flow rate in said flow channel of fluid system, and having a profile providing an artificial increase when measuring pressure parameters upstream, leading to a locally increased pressure drop on different sides of the profiled insert, directly proportional to the dynamic pressure component at a given location, wherein profile is made in form of flat inclined surface extending from support part of profiled insert, and a pressure collecting device upstream and downstream, made at a location located upstream and downstream relative to the profiled insert, for recording pressure upstream and downstream in said flow passage in fluid jet and providing upstream and downstream pressurisation signals which contain pressure information upstream and downstream, recorded for further processing to determine flow parameters in said flow channel in fluid jet by difference of measured pressures between pressure pickup signals higher and lower downstream in compliance with coefficient of carrying capacity of profiled insert.

EFFECT: technical result is reduction of total number of components required in system.
