Method for Detecting corrosion, erosion or accumulation of Product Elements VIBRATING Densitometer and Coriolis Flow Meter Calibration and Validation

摘要

A method and apparatus for validating the flow Calibration factor of a Coriolis flowmeter. According to a First realization, an improved material Density is obtained by Measuring the density of the material when the temperature of the material is equal to a Predetermined Reference temperature.According to a Second realization, a database Stores preprogrammed density / temperature relationships.Improved Information Density is obtained by Measuring the density and the temperature of the material, applying the density / temperature information from the database, and obtaining information Density compensated to a Predetermined Reference temperature.The information obtained for both embodiments of improved Density is not affected by changes in temperature and is used to validate the flow Calibration factor. The Flow Calibration factor Compensation for changes in pressure and changes in the composition of the material is obtained in a similar way.
