All floating types of alcohol meters (hydrometers) rely on the density of the liquid being measured and convert the density reading to an appropriate scale such as the Guy-Lussac scale (alcohol percentage by volume - %abv).
Quite often we get asked for hydrometers that can measure the SG (Secific Gravity) of liquids that is lighter than oil. Many of these requests concern the SG measurement of oils and other light petroleum products.
