An Instrument for the Measurement of Specific Volume in Liquids

An instrument was designed to measure the specific volume of liquids for pressures between 14.7 and 14,000 lb/square inch, and for temperatures between 0 degrees C and 100 degrees C. The instrument is based upon the ability of a differential transformer to detect changes in length with high precision. A description of the instrument, its present calibration, and the results obtained in a Dow Corning solution (DC 200) are given. (Author).
