Abstract

1,018,396. Measuring fluid flow. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 28, 1964 [Nov. 21, 1963], No. 46046/63. Heading G1R. In a pressure-sensitive device for indicating the rate of flow of fluid in a duct 1 a reservoir comprising two chambers 6, 7 interconnected by ducts 18, filled with an incompressible fluid, and closed by diaphragms 8, 9 and in which diaphragm 9 is subjected, through an aperture 4, to fluid pressure downstream of a Venturi throat 2 and diaphragm 8 is subjected, through an aperture 3, to the Venturi throat pressure the arrangement is such that the rate of flow above or below a predetermined value can be indicated by the actuation of a micro-switch 19.
