摘要: A method and apparatus for validating the flow calibration factor of a Coriolis flowmeter. In accordance with first embodiment, an improved material density is obtained by measuring when temperature equal to predetermined reference temperature. second preprogrammed data base stores density/temperature relationships. Improved information material, applying measured from base, obtaining compensated The both embodiments unaffected changes used validate factor. compensation pressure in composition similar manner.
