Coriolis Data from an Oil Well

Hi,

I am looking for an example of the data a coriolis meter would provide a flow computer; then I am looking for example calculations that the flow computer would calculate for barrels of oil per day based on the coriolis data.

Your friend,

AJ

  Via RS485 or hart signal you can collect the fluid data inform of flow(units/time) for both mass and volume. This will require you to read specific modbus addresses addresses.

  Team,
  
  Let me clarify, we are looking for example of data gathered using the coriolis on the inlet three phase separator, not a truck or pipeline LACT?

  In reply to adamjamesgibson:

  To reconfirm, is that an 'outlet' of a separator? Typically Coriolis is not installed on the inlet to a separator. Typical data is recorded via RS485 and includes volume rate, volume total, density and temperature. Frequently US oil and gas customers upgrade the MMI Coriolis with either Petroleum Measurement Software or Production Volume Reconciliation Software (PVR) to provide volumes at standard conditions (60 degF and 1atm). PVR has the additional advantage on the oil leg of a separator of being able to provide a watercut and identify any flashing or two-phase flow and providing a 'reconciled' total volume (oil volume minus volume due to gas or water). The watercut is determined via measured line density measurement versus input 'dry' oil and water densities at standard conditions. If you're looking for the Modbus mapping for the variables, let us know.
