The Design of Fluid Measuring Set and Controller
Based on One-chip Computer
Abstract :Nowadays, flow measure becomes more and more important。The supply of natural resource has been lacking。It is more important to measure the flux of important resource, such as the water, natural gas, petroleum and petroleum derivative, for saving. The flowmeter is required to be more precision. The flow measurement system for food processing industry、 chemical engineering in this paper adapts to the requirement of above consumers. The flow measurement system for food processing industry、 chemical engineering has the advantages of low power, high precision, light, long time use, low price etc。
A right flowmeters is chosen in this flow measurement system. At last, the paper chooses turbine Flowmeter to be the object of the study. The turbine flowmeter is affected by the characteristics of flowing medium, such as viscosity, temperature and density. The paper analyses the affected status of the characteristics of flowing medium to the turbine flowmeter. Some compensate formulae are presented in the paper. The smart flow integrating and displaying instrument can switch to display cumulative flux of quantity and cumulative flux of volume etc. Its parameters can be changed by manual key-press panel. The software of the instrument is modularized written to make the instrument working on high efficiency.
