Abstract

1363762 Fluid regulation UNITED KINGDOM ATOMIC ENERGY AUTHORITY 23 June 1972 [28 June 1971] 30246/71 Heading G3H [Also in Division G1] In a fluid-flowmeter comprising a fluidic oscillator having a main inlet jet 1, two outlet paths 4, 5 and control ports 2, 3 for directing the fluid issuing from the inlet into one or other of the paths, means being provided for measuring the frequency of oscillation of the fluid between the paths, this being proportional to the fluid flow-rate through the jet 1, the control ports 2, 3 are made greater in width, but of the same height, as the aperture defining the jet 1 thereby increasing the linear range and accuracy of the meter. The ports 2, 3 are preferably at least twice as wide as the aperture, and connected in a closed loop 7 to induce oscillation. Alternatively feedback may be induced from the outlet paths 4, 5. The fluid oscillations are detected by a differential pressure sensor (not shown) coupled to a frequency meter and located in a slot 9 between the outlet paths upstream of restrictions 10.
