Abstract
The invention concerns a device for measuring pressure in two points of a fluid flow, comprising: a frame () consisting of two plates () comprising each two planar surfaces, one outer () and the other inner (), and wherein one of the plates () is perforated with recess () closed by the other plate () to form an assembly of two chambers () comprising two planar walls () parallel to the surfaces () of the frame and a side wall () forming its periphery and a fluidic restriction channel () connecting the two chambers () with each other, and means () for supplying a measurement of the pressure in each of the chambers (). In order to improve the accuracy of the measurement, the side wall () of the chambers () is perpendicular to its two planar walls () and is configured such that the chambers () are spindle-shaped.
