The reliability of oil–water interface level control in three-phase separators is highly dependent on the accuracy and stability of level measurement instruments. This study evaluates the performance of displacer and differential pressure (DP) level transmitters for interface level measurement on the Medium Pressure (MP) Separator 532-V-02A at the CPP Hess Indonesia Pangkah LTD facility. The evaluation method was conducted through analysis of actual operating trending data and statistical assessment using standard deviation of the Process Variable (PV) for each instrument, with a sample size of N=50. The main results indicate that the DP level transmitter exhibits superior stability, with a standard deviation of 2.22% compared to 7.98% for the displacer, particularly under conditions where an emulsion layer is formed. The practical implications of these findings suggest that the DP level transmitter is more suitable for interface level control applications
