Traceable volume measurements using coordinate measuring systems

Accurate quantification of volume is important in many different applications, including calibration of containers for fluids, wear evaluation, and inspection of cavities and medical dispensing devices. Volume assessment methods based on dimensional measurements have the potential to be more accurate than gravimetric ones. This paper proposes and compares different methods for obtaining traceable volume measurements, based both on contact and noncontact coordinate measuring techniques, including computed tomography. The focus is on the design of measurement procedures and their applicability for users in industry. Measurement methods are validated with reference to two case studies, using calibrated reference parts.
