Abstract
An automatic liquid density measurement device includes a receptacle configured to contain the liquid, a float configured to be submerged in the liquid when it is contained in the receptacle, and an electronic system. The electronic system includes a first electromagnetic sensor configured to make a reference measurement relative to the electrical properties of the liquid, a second electromagnetic sensor configured to make a measurement of the volume of the liquid displaced when the float is submerged in the liquid, and an electronic circuit coupled with said first and second electromagnetic sensors to determine the density of the liquid based on the measurement of the physical properties of the liquid and the measurement of the volume of the liquid displaced.

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.
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.
