Abstract

616,186. Indicating fluid flow. WEISS, F. Aug. 6, 1946, No. 23251. Convention date, Aug. 9, 1945. [Class 40 (i)] In a fluid-flow meter comprising a differential manometer connected in the usual way to a venturi tube, the legs 6, 7 of the manometer are shaped according to the equation y=1/a (#ax. #1-ax+sin-<SP>1</SP> #ax), where x, y are the vertical and horizontal components respectively and a is a constant depending on the highest differential pressure to be measured. Resistance wires 3, 4 extend axially along the legs 6, 7 from electrodes 8, 9 into the mercury or other conducting liquid 18 to support 11, 12. As the fluid flow varies and hence the liquid levels in the legs 6, 7, the resistances between the common electrode 10 and the electrodes 8, 9 vary differentially and operate a flow indicator, recorder or integrator 16 of the cross-coil or induction type in known manner. The rate of fluid flow is proportional to the square root of the differential pressure and the shaping of the legs 6, 7 according to the given relationship gives a linear relationship between fluid-flow and the indicator displacement. The tubes 6, 7 may be made of insulating material or of steel with an inner insulating lining.
