VX3000流量积算记录仪的设计和应用

Design and Application of VX3000 Flow Totalizing Recorder

主要探讨了流量计量的重要性以及蒸汽和天然气等流量温压补偿的基本原理。重点阐述了在此基础上设计的VX3000流量积算记录仪的流量积算、流量显示、记录、报表和联网功能。然后介绍了VX3000流量积算记录仪的外壳、电源、A/D采样、微处理器、存储器以及抗干扰技术,最后介绍了VX3000流量积算记录仪的现场应用。

The importance of flow metering, and the basic principle of temperature compensation and pressure compensation in flow measurement of steam and natural gas, etc., are mainly discussed. Firstly, the functions, including flow totalizing, flow display, record, report and networking, of the VX3000 flow totalizing recorder which is designed on above basis are presented emphatically. Then, the enclosure, power supply, A/D sampling, microprocessors, memory and anti-interference technology of the recorder are introduced. Finally, the applications of VX3000 flow totalizing recorder in the fields are described.
