Improving accuracy by adding additional sensors to a density measuring system

Methods, systems, and devices for measuring density involve performing a buoyancy measurement with respect to a product in a tank and determining a first density based on the buoyancy measurement. A pressure measurement of pressure in the tank is performed, and a second density is determined based on the pressure measurement. An offset of the buoyancy measurement is calculated using the first and second densities, and the offset is applied to correct the first density measured at the predetermined position in the tank.
