The cryogenic fluids density reference system has been used to evaluate three basic types of densimeters: the vibrating element type, the dielectric cell type and the displacement type. These meters were used to measure densities in liquid methane and liquid methane mixtures with ethane, propane, normal butane, and nitrogen. Measurements were made over the density range from 400 to 480 kg/m/sup 3/, temperatures from 108 to 130/sup 0/K, and pressures from 1 to 3 bar. A hundred measurements were made at various densities, temperatures, pressures, and compositions.
