Abstract

1,210,710. Measuring fluid flow. R.E. CLEARY. May 3, 1968, No.21165/68. Heading G1R. In a fluid-flow measuring device a differential pressure measuring device 50 has one side 52 connected to an opening 38 between the ends of a flow passage 30 of a progressively increasing crosssection in the direction of flow its second flow passage of a progressively reducing cross-section 92 downstream of the passage 30 is connected between the ends thereof to the other side 54 of the differential pressure measuring device. The fluidflow through the device can be obtained from the differential pressure readings.
