The document records daily measurements from various totalizers and flow meters from December 5-12 that measure liquid transfers and discharges. It compares the readings from two systems - Optiflux and PLC - to check for deviations and communication errors. On some days it notes issues like a PLC reset or shield connection being finished. Overall it analyzes the data to check that the systems are recording measurements accurately and within acceptable error rates.
