What do flow diagrams use to represent equipment?

Flow diagrams use symbols to represent equipment. These symbols are standardized and convey specific information about the types of equipment, such as pumps, valves, and tanks. By using symbols, flow diagrams provide a clear and concise way to visualize the processes within a system, allowing operators and engineers to understand the layout and function of different components at a glance. This symbolic representation also facilitates easier communication among professionals, ensuring that everyone understands the same information without ambiguity that might arise from using pictures or descriptive text.
