ABSTRACT:
A method of manufacturing a high pressure vibrating tube densitometer comprising enclosing twin flow tubes within an outer shell, wherein the outer shell comprises portals for the installation or replacement of internal components. A vibrating tube densitometer system for determining the density of a high pressure fluid in a pipeline, the system comprising a densitometer in communication with a controller, the densitometer comprising twin straight flow tubes spaced parallel apart within an outer shell comprising one or more portals for the placement of internal components, wherein the controller is in signal communication with a signal pickup, a tube driver, and the at least one temperature or pressure sensor and calculating the density of a fluid having a pressure of greater than 1500 psi.
