Custody Measurement, Fiscal Flow Metering, Meter Calibration, Uncertainty Calculations and Loss Control

Introduction

This intensive training course covers the concept of custody transfer, fiscal flow metering, meter calibration, uncertainty calculations and loss control of petroleum products. It is divided into 5 modules:

Module 1: Accuracy & Process Measurement This module covers basic definitions, such as viscosity, repeatability, cavitation etc.; flow profiles and the effects on measurement; volumetric and mass flow rate. Accuracy is important in terms of uncertainty of measurement; calibration; technical specifications and process requirements. Flow Measurement including orifice plate and DP transmitter; multi-beam ultrasonic flowmeter; Coriolis mass meter; turbine meters amongst others. Level Measurement, traditional methods such as capacitance and hydrostatic techniques are covered together with more modern technologies such as ultrasonic and radar measurements.

Module 2: Custody Transfer & Fiscal Flow Metering This module examines the requirements of OIML R117; the subject of Custody Transfer in detail terms; flow calibration, dynamic and static; types of calibration rigs and calibration systems plus prover systems.

Module 3: Terminal & Pipeline Systems Included in this module are, terminal tank gauging; Lease Automatic Custody Transfer (LACT); sediment and water considerations; operational issues and associated equipment. Pipeline considerations including paraffin content; pipeline pressure and process characteristics. Truck custody transfer, marine and aviation, on-loading and offloading etc.

Module 4: Monitoring and Controlling Losses Loss control systems– an applied approach – model-based system; leak detection / leak testing. Case studies of marine applications; measurement surveys and measurement reports. Multi-phase flow metering and applications.

Module 5: API Standards and Flow Meter Selection API measurement standards and volume correction tables; temperature compensation; SG versus API gravity; net volume calculation exercise. Guidelines for flowmeter selection.

Objectives

Upon the successful completion of this program, participants will be able to:-

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
