Abstract
An instrument is described for the continuous volume measurement of small (3.7 ml) samples of liquids as a function of temperature. The sample is sealed in a stainless steel bellows chamber. Volume changes are measured with a linear variable differential transformer while temperature is measured by means of a thermistor and associated circuitry. Volume changes of sample can be determined to better than 1.0×10−4 ml over a temperature range of 10–60°C. The maximum sample volume change is 7%.Keywords
