Abstract
To minimize loss of pressure energy in metering fluid flow by means of primary flow tube elements, the contour of the throat inlet section of the flow tube is that which produces a constant rate of acceleration of flow through the inlet to the throat section. The contour equation is given. At least in larger sizes of flow tubes, the inlet section is formed of thin metal such as stainless steel and arranged in such a way that it is not subject to mechanical stress in the installed assembly.
