Abstract
900,340. Fluid flowmeters. WILLCOCKS, R. G. W. April 28, 1961 [May 10, 1960],-No. 15507/61. Class 69 (1). Apparatus for indicating the rate of flow of a fluid includes a conduit of constant crosssectional area and of slope which continuously increases from the horizontal to the vertical and in which a rolling element of density greater than that of the fluid is positioned by the flowing fluid; means being provided to indicate the position of the rolling element in the conduit. The conduit may be circular, rectangular or triangular in section and the rolling element may be a ball or a cylinder. In an example described, the conduit is formed by two transparent side-sheets 23 spaced apart at the top and bottom by similarly-shaped bars (Fig. 3, not shown) the top surface of the bottom bar serving as the smooth track for a ball 30. The sheets 27 are held between plates 26 with slots 27 which reveal graduations on the transparent sheets calibrated in rates of flow. For the flow rate to bear a linear relationship to the displacement from zero of the ball at any position (X, Y) in the conduit (stated in Cartesian co-ordinates) is:- where " a " is a constant and # is a variable having any value between zero and # radians.
