FLOWMETER Russian patent published in 2018 - IPC G01F1/34 

FIELD: measuring equipment.

SUBSTANCE: flowmeter contains a body with a crosspiece that repeats the shape of the aerodynamic wing section, the bridge rigidly fixed in the device body and has channels for communicating its upper and lower surfaces with the sensing element of the differential pressure gauge. The differential pressure gauge scale is calibrated in flow dimensions. In the device body in front of the crosspiece, a flow stabiliser is rigidly fixed, giving it a laminar flow form.

EFFECT: increased accuracy, reliability and safety of flowmeter operation due to crosspiece immovability, repeating the shape of the aerodynamic wing section, and providing a laminar form to the pumped medium flow, the absence of moving elements eliminates any kinds of mechanical defects during flowmeter operation.
