Abstract
A device for measuring the volumetric flow rate of a fluid, particularly a lubricant fluid in a hydraulic circuit, comprising a distributor block provided with an entry bore and an exit bore, and a feed duct and return duct respectively to and from a measurement block removably supported by the distributor block, the distributor block having elements therein for adjusting the fluid feed to the measurement block, the measurement block comprising interface elements between the two blocks, a member eccentrically orbiting within a chamber defined by the casing containing the measurement block and interface elements, and guide elements for the movement of the member. A sensor is connected to the measurement block to ascertain the movement of this member, this sensor being connected to an electronic microprocessor circuit arranged to determine the fluid volumetric flow rate through the distributor block.
