About the course

This course presents the methodology for developing and applying instrument and control drawings and the ISA Standards available to assist in this effort. You will develop actual documents for a simple project to aid your understanding.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Define instrument and control systems, including: Process Flow Diagrams, Piping and Instrumentation Drawings (P&IDs), Instrument Lists, Specification Forms, Logic Diagrams, Location Plans, Installation Details, Loop Diagrams
  • Explain the type of information included on each document
  • Identify the sequence of document development for a typical project
  • Identify some process control devices and the symbols used to define them
  • Identify the ISA Standards available to assist you in developing and understanding instrument and control documents
