Nutshell: Ultra Sonic Flow Meter (USFM) performance degradation due to dirty Sensors.
Instrument: Ultrasonic Flow Meter Make: SICK MAIHAK Model: FLOWSIC600
Application: CUSTODY TRANSFER Location: GCS Ramnad Commissioned on: May 2010
Errors Identified:
- Observed Critical Errors “Meter Data Invalid” & “ Flow Meter Measurement fail” in Flow Computer.
- Observed USFM Performance degraded to 49% (Usually it used to maintain above 95%) in MEPAFLOW600 software.
- Oberved Error: 3003 (Measurement invalid) in Field USFM Display.
Typical Values of USFM:
Observations in MEPAFLOW600 SOFTWARE:
Problems Identified:
Since
-> Performance of Path 3 & 4 = 0 %
-> Wave forms of Path 3 & 4 are shifted
The Probable Reason is Dirty sensors.
