ABSTRACT:
A system and method for obtaining a fluid density of a fluid in a tank includes at least two sensor/transmitter assemblies to obtain fluid pressure measurements at different fluid levels in the tank. After the respective fluid pressures are obtained, the fluid density is calculated as a function of the respective fluid pressure measurements. The sensor/transmitter assemblies have substantially similar variation characteristics so that possible measurement variations are eliminated during fluid density calculations.
