Check Metering at a Ethylene Pipeline

A major pipeline operator was looking for a check meter at an ethylene product pipeline to verify a differential pressure meter at a custody transfer point.

Though there was virtually no straight piping to work with, a four month test with a FLEXIM HPI flow meter (dual beam configuration) ensured that it proved capable of a consistent, highly repeatable as well as accurate flow measurement.

Moreover, the HPI flow meter was able to detect the failure of a flow compensating pressure sensor which caused the reference flow meter to spike.
This successful test resulted in a permanent installation and more flow meters installed on the ethylene plant.

Advantages

• Ideal check meter at custody transfer points – zero point stability, no drift
• Excellent performance under non-ideal flow conditions
• Bi-directional flow capability – low cost of installation
