The purpose of buffer tanks (accumulators) is to store process fluids to ensure adequate supply for downstream equipment and processes at all times. It is thus essential to continuously monitor the level and ensure that there is sufficient liquid in the vessel to prevent a run-dry situation, or to avoid overfilling of the vessel which may result in an overspill. This can be reliably achieved with the Rosemount 5300 Level Transmitter. Point level technology such as the Rosemount 2130 Level Switch may be installed at high and low level positions in the vessel for high and low level alarm. Magnetic level indication technology such as the Rosemount 9930 Magnetic Level Indicator may be installed for added redundancy and safety. The Rosemount 9930 provides a clearly visible level indication at 100-feet.
