Title:
DEVICE FOR CONTROLLING AND MANAGING THE VISCOSITY AND DENSITY OF A FLUID
Document Type and Number:
WIPO Patent Application WO2007125555
Kind Code:
A8
Abstract:
A device (1) for controlling and managing the viscosity and density of a fluid (2), comprising a vessel (3) provided with an outlet (4) and with a second overflow port (5) at a preset level (6), a circuit (8) for drawing fluid (2) from a reservoir (7) and for introducing the fluid into the vessel (3). The device (1) comprises a weighing unit (17), on which the vessel (3) rests, an element for detecting the percolation time of the fluid (2) through the outlet (4) between an upper level (6) and a preset lower level, a computer (19) for controlling the device (1) which is interconnected to all the components, and at least one dispenser (22, 23) of a suitable top-up fluid. The top-up fluid can be dispensed within the fluid (2) to be controlled following measurements differing from the predefined values of the variation of the weight of the fluid (2) discharged in a constant percolation time and of the percolation time interval required to discharge an amount of fluid having a constant weight.
