After the sludge has passed through the digester, it is transferred to a storage or buffer tank, where it is stored before it is sent to the dewatering process. The Rosemount 1208 Non-Contacting Level Transmitter provides continuous and robust level measurements in the sludge storage tanks so that the sludge supply can be optimized, and plant operators can avoid unnecessary downtime while ensuring optimal feeding to the dewatering processes. With plastic intermediate tanks, the Rosemount 1208 provides continuous and accurate measurements directly through the closed plastic tank roof.
