Measurement is essential for industrial production process of a lack of technology.Measurement technology development, but also from the objective of a country or region's industrial development.The more advanced measurement technology, industrial development in the region higher. The liquid density measurement is a very important industrial techniques are a technology.This paper describes, from design concept to the specific process every step of the design process.Including the goal-liquid density measuring units of this machine-driven program, transmission programs, supporting programs, the implementation of programs and technology programs of the design process.In the design process, supplemented by computer design, greatly saving design time.In this issue, the result of mechanical design of the selected parameters are the most commonly used parameters in the manual, so the design process, and not much difficulty, but the design process too much data, very complex.From an objective point of view, also explains the design issues of economy.
