Flow Measurement Technology In Compressed Air Systems Applications And Research

In this paper, the design of a gas-flow measurement system for a compressed air system is introduced in detail, included hardware and software.Compressed air as an energy has many specialties such as safety, continuity. It has been applied widely in chemical and electric power industry. For a system which takes compressed air as power, the consumption of the compressed air is an important reference to evaluate the system capability. Since most of gas-flow meters are expensive, the gas-flow measurement technique has not been used widely in many compressed air systems.For researching and designing a gas-flow meter which can be accepted by general client, common gas-flow measurement technique used in industry is regarded as a background in this paper, and use hot wire/film technique to measure gas-velocity. And then calculate and display the gas-flow with a single-chip computer. The measurement system also can control the gas-flow according to common technical requires which are applied in a compressed air system. As a result, a valid method is provided to use gas resource in reason and reduce the cost in industry produce.
