· The Supermarket App Data Flow Diagram example contains five processes, one external entity and three data stores. Although there is no design guideline that governs the positioning of shapes in a Data Flow Diagram, we tend to put the processes in the middle and data stores and external entities on the sides to make it easier to comprehend.

Introduction to flow meter reference design Flow meter based on MC9S08GW64 is a lowcost, lowpower system. This reference design is specifically targeted for gas and fluid meters. This design fulfils the basic market requirement for the Flow meter: lowpower, lowcost, able to run on battery, and with automated meter reading (AMR).
What is Data Flow Diagram? Data flow diagram ie. DFD in software engineering is a way of representing flow of data of a process or a system. A DFD uses defined symbols like circles, arrows and rectangles to represent data input, output, storage points and routs between each destination.
· Introduction. The process flow diagram (PFD) is a critical component of process design. It is absolutely necessary that chemical engineers know how to read process flow diagrams because it is the primary method of detailing the process and design information.
