The disclosed active pressure gage for a flowmeter is intended for use in flows containing solid impurities. The gage is constructed of a tubular body containing a diffuser segment (3), a segment (4) with a maximum cross section, and a convergent tube segment (6), placed along the course of the fluid flow; the interior of the tubular body further contains a retaining element (22) positioned concentrically and having in its wall openings (23) which prevent larger solid impurity particles from clogging the apertures (9, 13, 17) that are used to tap pressure.
