Sales Metering Calibration & Operations

Details :

The smallest error in the flow measurement of materials like oil, gas, or chemicals as being transferred between a producer (supplier) and customer may cost a company millions of dollars in a year.

Custody Transfer takes place any time fluids are changing possession from one party to another e.g., from producer to pipeline, pipeline to plant, or pipeline to storage facility. Custody Transfer refers to any agreed metering condition in a sales contract between supplier while Fiscal Metering refers to metering of a commercial transaction that should comply with legal obligations and so in this case there is no discussion about the metering requirements.

This course introduces participants to a variety of flow measurement technologies that are used in custody transfer applications while the objective is to gain an understanding about how to achieve the requirements by means of differential pressure (DP) measurement, Turbine meters, Positive displacement meters, Coriolis flow measurement, Magnetic and Ultrasonic flow measurement.

Participants will gain the ability to determine if a metering system is fit for the purpose while other key learning objectives of this course include the understanding of the principles of Fluid Dynamics, Meter runs, Flow computers, related Quality systems, applied specification of Accuracy terms, Calibration and Proving systems.

At the end of this course the delegates should be able to describe: 

Ø  Utilities required for fiscal flow metering

Ø  The aim of Loss Control

Ø  Fiscal metering station

Ø  Fluid Dynamics – Liquids and Gases

Ø  Energy conservation according to Bernoulli’s Law

Ø  Applied Custody & Fiscal Metering contracts

Ø  Moisture and HC Dew-point measurements
