Abstract: PURPOSE: A wet gas flow measuring device is provided to easily adjust fluid level, to easily grasp integral value and to improve convenience by converting detected gas flow into flow under standard temperature and air pressure. CONSTITUTION: A device includes a drum(208); a magnetic coupling; an encoder; a level adjusting part; and a conversion/display part. The drum comprises a fixed number of compartments and an axis and has an inlet and an outlet of gas separated from each other and is filled with sealing fluid. The magnetic coupling couples the drum in a chamber(202) and the encoder outside the chamber by magnetism so that an axis of the encoder rotates by rotation of the drum. The encoder is driven by the magnetic coupling as the drum rotates to output pulse proportional to the rotation frequency of the drum. The level adjusting part has a bar(220) inserted by screw to adjust level of the sealing fluid by adjusting volume of the bar sinking under the sealing fluid. The conversion/display part calculates gas flow data based on the pulse to convert into flow under standard temperature and air pressure and display.
