摘要
流量仪表是能源计量仪表的重要组成部分,合理的选用流量仪表是计量准确的可靠保证。该文介绍了一款高精度智能流量二次表,它对影响流量的流出系数、流体膨胀系数以及气体压缩系数等参数进行全动态补偿,保证了仪表的测量精度。解决了原装置测量数据长期计量不准的难题,提高了生产效率以及成品合格率。
The flow meter was an important part of energy meters,reasonable selection of flow meter was the reliable guarantee for accurate measurement.This paper introduces a high precision intelligent flow secondary tables,this tables for whole dynamic compensation the parameter which influence the quantity of flow,such as discharge coefficient,fiuid expansion coefficient,gas compressive coefficient,ensure the high precision of measurement instrument.To solve the problem of the original device measuring data inaccurate for along time,improve the production efficiency and the rate of qualified products.
