The Fluke 7250 pressure controllers are used to measure liquid level and specific gravity in Tanks 7.4 and 8.3, providing data for Nuclear Material Accountability. However, these laboratory-grade instruments have proven unreliable in industrial environments. Furthermore, the high accuracy they offer cannot be fully realized due to the limitations of the calibration process performed at SRNL. As an alternative, the Rosemount 3051S Ultra differential pressure transmitter is recommended.
