The liquid to be measured is filled into a tube (resonator) which is set into resonance vibration The energy density is a function of the weight of the battery, and the volumetric energy density (in whr/litre3) is a function of volume of battery The resulting oscillation frequency, which depends on the density of the liquid and the rigidity of the.
Calculators - Battery Design
The characteristic frequency changes depending on the density of the filled sample
Via a precise measurement of the characteristic frequency the true density of the sample is determined
As the density of the sample increases, the oscillation frequency decreases (heavier sample = slower oscillation) The instrument measures this frequency and calculates the density with. The density meter calculates the density of the sample by comparing the measured resonant frequency with the reference frequency (in the absence of a sample) Density or brix measurement of various beverages such as milk, soft drink, fruit drink, etc
Measurement of alcohol or extract concentration of beer, whisky, wine, shochu(japanese distilled alcohol),. Flooded batteries are filled with electrolyte This electrolyte changes in density according to the state of charge A fully charged battery will have a high acid content which gives it a higher specific gravity
