Abstract

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.

Description

technical field [0001] The invention relates to a digital liquid velocity meter. Background technique [0002] Digital devices for measuring the flow rate of liquids are known, designed to be installed along pipes conveying the liquid, and provided with an electronic card provided with a display allowing direct reading of the flow rate of the conveyed liquid . [0003] These devices consist of a body defining a duct for delivering the liquid, and into this duct is inserted a small turbine provided with a magneto that sends pulses to a microprocessor, also included in the body, And it is equipped with an electronic card with a display. [0004] The known devices are unidirectional, i.e. they are adapted to operate in which the liquid flows in only one direction, so they do not need to be provided with means capable of resisting the axial thrust which is transmitted in this direction to the turbine associated with the turbine. on one of the supports of the coupled shaft. ...
