Claim 13:
14. An automatic liquid density measurement method, comprising:
pouring the liquid into a receptacle,
using a first electromagnetic sensor to make a reference electromagnetic measurement relative to electrical properties of the liquid contained in the receptacle,
using a second electromagnetic sensor to make a first electromagnetic measurement of a level of the liquid in the receptacle,
introducing a float into the liquid contained in the receptacle so as to be partially submerged in the liquid,
using the second electromagnetic sensor to make a second electromagnetic measurement of the level of the liquid in the receptacle, and
using a microprocessor to determine a density of the liquid according to measurement of physical properties of the liquid and the first and second level measurements, the physical properties including the conductivity and permittivity of the liquid.
