In order to improve the sensitivity of the sensor, a special signal processing algorithm was implemented in the development phase. It is based on false signal suppression during setup and commissioning. The sensor subtracts this false signal suppression from the visible echo curve. The result is a straight echo line.
The responsible technicians were eagerly awaiting the results of the practical test. As expected, the test ran smoothly. Commissioning was simple – the application was configured as a “normal” level measurement. Thus, no special settings were required to ensure a reliable measurement with sufficient measurement certainty.
Test run with a positive outcome
It quickly became apparent that the advantages of the self-compensating VEGAFLEX sensor had a positive effect on measurement accuracy, even with constantly changing crude oil quality. To be on the safe side, the displacement measurement was left in place so that the measured values could be compared with one another. The test run was consistently positive for 1.5 years, with no malfunctions during the entire period. After this successful test run, another desalinator with a VEGAFLEX 86 with reference section was put into operation last year.
