A digital liquid flow rate meter that comprises a body (2) adapted to delimit a conduit (3) for conveying liquid with two connectors (3a, 3b) which provided respectively with male threading and with female threading. In the conduit (3) a turbine (4) is inserted provided with a magneto (4a) that transmits impulses to a microprocessor comprised within the body (2) and provided with an electronic card (5) complete with display (5a) for direct reading of the flow rate of liquid conveyed. The turbine (4) is associated with a shaft (7) that transmits selectively at the ends, according to the direction of travel of the liquid, an axial thrust to corresponding supports (8, 9) that are inserted in the conduit (3). The shaft (7) is provided with anti-wear elements (8b, 9b, 10, 11) that are resistant to wear in both directions of travel of the liquid.
