摘要
A simple, versatile, magnetic float densimeter that can be used at high pressures (1200 bars) to measure the density of liquids is described. The system has been calibrated with water at 25 degrees C from 1 to 1200 bars, demonstrating a sensitivity of 0.5 ppm and a precision of 11 ppm. The accuracy of the densimeter has been verified by measuring the densities of NaCl solutions at 25 degrees C and from 1 to 1200 bars. Excellent agreement with previously published data was achieved.
