QUALITY MAINTENANCE OF FLOW MEASUREMENTS IN INDUSTRY
Abstract
There is keen interest in the total accuracy of flow measurements in industry. Total accuracy is defined as the accuracy of the whole measurement chain which can be determined only in a field calibration. Indmeas has for several years carried out quality maintenance work for industry using the radiotracer methods for field calibrations of liquid and gas measurements.<BR />Comprehensive data from these calibrations show that the dominating uncertanties of flow measurements in industry lie outside the flow meters themselves. The large error components, however, are often fairly stable and can be eliminated by constant corrections.<BR />Experiences show that by using a quality maintenance system based on repeated field calibrations an accuracy level of 1-2 % is effectively reached and maintained.
