PID is a schematic illustration of a functional relationship between piping, instrumentation and system components. PID's shows all piping including physical sequences of branches, reducers, valves, equipment, instrumentation and control interlocks. The PID's are used to operate process systems. A PID should include:

A flowchart is a generic tool that can be adapted for a wide variety of purposes, and can be used to describe various processes, such as. a manufacturing process, an administrative or service process, or a project plan. When to Use a Flowchart. To develop understanding of how a process is done. To study a process for improvement.
Piping and Instrumentation Diagrams (PIDs) use specific symbols to show the connectivity of equipment, sensors, and valves in a control system. These symbols can represent actuators, sensors, and controllers and may be apparent in most, if not all, system diagrams. PIDs provide more detail than a process flow diagram with the exception...
Drafting Symbols. Symbols provide a "common language" for drafters all over the world. However, symbols are meaningful only if they are drawn according to relevant standards or conventions. This document describes and illustrates common dimensioning, GDT, architectural, piping, and .
The most common symbol used in a flowchart is the rectangle. A rectangle represents a process, operation or a task. The next most common symbol is the diamond which is used to represent a decision. There are many other flowchart symbols like Sequential access storage, Direct data, Manual input etc.
