TANGENTIAL TURBINE-TYPE FLOW RATE CONVERTER Russian patent published in 2012 - IPC G01F1/10 

FIELD: machine building.

SUBSTANCE: proposed device comprises case with cylindrical measuring chamber, tangential inlet and outlet channels, straight-vane turbine arranged vertically in said measuring chamber, flow turbulisers, and differs from know designs in that said inlet and outlet channels feature rectangular shape and the following sizes: width - 1-0.85…1 of vane width, height - 1/6 of vane height. Note here that inlet and outlet channels are arranged along tangent to measuring chamber inner diameter circle so that inclination a of said channels to axis passing along center of turbine makes 45°…60°. Note also that sizes of outlet channel cross-section sizes are 1.1-time larger than those of inlet channel.

EFFECT: higher accuracy of measurement and expanded range of measurements.
