Claim 0:
1. An automatic liquid density measurement device, comprising:
a receptacle configured to contain the liquid
a float configured to be partially submerged in the liquid when it is contained in the receptacle, and
an electronic system including:
a first electromagnetic sensor configured to make a reference measurement relative to electrical properties of the liquid,
a second electromagnetic sensor configured to make a measurement of a volume of liquid displaced when the float is submerged in the liquid, and
an electronic circuit coupled with the first and second electromagnetic sensors to determine a density of the liquid based on a measurement of physical properties of the liquid and the measurement of the volume of the liquid displaced, the physical properties including conductivity and permittivity of the liquid.
