A fluid flow meter with configuration of flow generation and flow sensor is intended for measuring a flow rate of working fluid (a gas or a liquid) passing through an inner cavity. The meter is a compact measuring apparatus of a small size, resistant to disturbances and distortions in the structure of the measured fluid flow. The fluid flow meter with configuration of flow generation and flow sensor is comprised of the following components: a housing (1) having an inner chamber (2) and a depression (3) configured to generate the flow; a flow sensor (4) arranged inside the housing (1) of the gas meter for measuring the flow velocity of the fluid; an adapter (5) to adjust different diameters of flow sensors and an outlet of the meter; a flow preparation device (6) intended for dissipating and stabilizing the flow of the fluid; an inlet (7) of the flow of the measured fluid; an outlet (8) for fluid flow out of the meter; an electronics unit (9); a coarse filter (10); a shut-off valve (11); a fluid leak detection sensor (12).
