Flow Measurement Field Calibrations by Radioisotope Tracers in the Off-shore, Oil and Gas Industry

摘要

Field calibrations by the radiotracer transit time method constitute an efficient basis for flow measurement quality assurance in the process industry. It is a flexible, reasonably low cost method with a calibration uncertainty compatible with the requirements set by the rules of the CO_2-emission trade and fiscal measurements. In the custody transfer measurements of oil refineries and natural gas networks this method is a new promising alternative to traditional quality systems based on tank level measurements and laboratory calibrations. The method has also been developed to meet the specific measurement circumstances prevailing on offshore platforms as well.
