ONLINE: Data Reconciliation in Flow Metering (PRE941)


    This course emphasizes the criticality and application of Data Reconciliation to flow metering data. The basic principles covered will apply to all measured data which is required to be reconciled.

    Course Structure: 6 modules of 2.5 hours each, delivered over 3 days
    Each day will consist of 2 modules of 2.5 hours, with multiple breaks.

    Course Level: Foundation
    Duration: 3 days
    Instructor: Mohit Narain

    Designed for you, if you are...

    This course is suitable for professionals at any level working in Process Engineering.

    Prerequisites: Professionals with any engineering qualifications as well as those conversant with basic principles of minimisation and preliminary knowledge of basic statistics shall derive maximum benefit.

    How we build your confidence

    • Highly interactive instructor-led course
    • Practical examples will be presented and adequate exposure will be provided to the students through exercises
    • The instructor is skilled in reconciling flow meters and experienced in training engineers on the basics of this application
