| 1. 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 resealable portals for the placement,
replacement, and operation of internal components, said internal components comprising:
a driver positioned adjacent the twin flow tubes for initiating and maintaining resonant vibration of the twin flow tubes;
at least one pickup positioned adjacent the twin flow tubes for sensing the motion of at least one twin flow tube and transmitting
a signal indicative of the response of the vibration of the at least one flow tube; and
at least one temperature or pressure sensor,
wherein the controller is in signal communication with the pickup, the 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.
