Abstract
A device for measuring the flow of a fluid in a pipe by creating aneasily measurable pressure differential which is related to flow comprises a diaphragm transversely contained in the pipe or an associated branch pipe. The diaphragm has a multiplicity of closely spaced fluid flow holes which are so shaped as to increase fluid flow velocity through the diaphragm, and means are provided downstream faces of the diaphragm said means being intended to be connected to a differential pressure indicating or recording instrument from which a fluid flow measurement can be derived.
