Abstract
A densimeter is provided having a pump which impels a liquid at a constant volume through a fixed orifice. A pressure transducer measures the pressure drop of liquid across the orifice and sends a signal to a microprocessor. A microprocessor determines the density of the liquid which is equal to the pressure drop divided by a constant times the square of a volumetric flow impelled by the pump.
