Abstract
A density measuring device is described having: a housing, internally defining a first chamber, designed to contain a fluid the density of which it is desired to measure, and housing, in a measurement operating condition, a float, designed to be immersed in the fluid; and an electronic circuit that detects a value of the density as a function of a thrust sustained by the float due to the effect of the fluid; the housing further defines a second chamber, designed to contain a filling gas and to house the float in a cleaning operating condition of the float, distinct from the measurement operating condition, for removing gas bubbles and/or solid particles that have adhered to an outer surface of the float during the measurement operating condition.
