ABSTRACT:
A method of compensating for at least one of pressure and density with a Coriolis meter, the meter having two modes of vibration impressed thereon, a fluid in the meter altering the modes of vibration to produce altered modes of vibration. The method includes the steps of: (1) measuring both the altered modes of vibration with a detector circuit at a selected working point and (2) simultaneously solving for the at least one of pressure and density, the at least one of pressure and density directly determined thereby to allow resulting flow-related signals produced by the meter substantially insensitive to a change in the at least one of pressure and density.
