Zusammenfassung
(EN)
Flowmeters are described in which a sensor signal received from a sensor that is attached to vibratable flowtube, so as to determine properties of a fluid within the flowtube, contains a drive signal component and a coriolis mode component. The flowmeters are operable to determine drive parameters of the drive signal component, as well as coriolis parameters of the coriolis mode component. By analyzing the sensor signal based on the drive signal parameters, and not on the coriolis signal parameters, the flowmeters are able to provide stable and accurate determinations of the properties of the fluid.
(FR)
L'invention concerne des débitmètres, dans lesquels un signal de détecteur reçu d'un détecteur rattaché à un tube d'écoulement vibrant de manière à déterminer des propriétés d'un fluide au sein du tube d'écoulement, renferme une composante de signal d'activation et une composante de mode Coriolis. Les débitmètres fonctionnent afin de déterminer des paramètres d'activation de la composante du signal d'activation, ainsi que des paramètres de Coriolis de la composante de mode Coriolis. L'analyse du signal de détecteur reposant sur les paramètres du signal d'activation et non sur les paramètres du signal de Coriolis permet aux débitmètres d'engendrer des déterminations stables et précises des propriétés du fluide.
