Abstract: Automation converts a work process, procedure, or equipment to automatic rather than human operation or control.Measuring solid density with high accuracy is carried out using the hydrostatic weighing method, which is one of the urgent requirements for automation in National Metrology Institutes (NMIs).This paper describes the automatic system for measuring density of solid objects in the National Institute of Standards (NIS).A Programmable Logic Controller (PLC) controller and a Human Machine Interface (HMI) control automatic weighing operation.The system consists of a main cabinet, assembly elevating platform, Mass carrier, and Water bath.The system has three induction motors for automatic calibration; the first motor is used for the assembly elevating platform.The second and third motors are used for mass carriers.This paper provides a complete description of the automation system.The feasibility of the automatic system is described using simulation software.The results of motion and the automatic system enhance the ability of the system control to measure the solid density.Finally, experimental measurements are helpful for automatically measuring the solid density of standard mass ranging from 1kg up to 20kg.
