Deltapilot S FMB70 Level measurement in closed tanks with pressure overlay You can determine the differential pressure in tanks with pressure overlay using two Deltapilot S probes. The measured pressure values of the two probes are sent to a signal processing unit such as Endress+Hauser RMA or a PLC. The signal processing unit or PLC determines the difference in pressure and uses this to calculate the level and the density where necessary. ➁ ➂ ➀ P01-FMB70xxx-15-xx-xx-xx-001 Level measurement in a closed tank with pressure overlay 1 2 3 Probe 1 measures the total pressure (hydrostatic...
