JLS 均速管流量计是马鞍山钢铁学院自动化系与扬中化工仪表配件厂共同开发研制的速度式流量计,具有压力损失小、节能效果显著、使用安装方便等优点,尤其在大管道流量测量方面有广阔的前景。化工部设备总公司和化工部生产综合司于1985年4月8日至9日在江苏省镇江市主持召开了 JLS 均速管流量计鉴定会。通过中国计量科学研究院、机械部开封流量测试中心的检定和南京栖霞山化肥厂等用户一年来的试运行,大会认为 JLS 均速管
JLS are speed tube flow meter Maanshan Iron and Steel Institute of Automation Department and Yangzhong Chemical Instrument Parts Factory jointly developed speed flow meter, with a small pressure loss, energy-saving effect is obvious, the use of easy installation, etc., especially in large pipe flow measurement Broad prospects. Ministry of Chemical Industry Equipment Corporation and the Ministry of Chemical Industry Production Division in April 8, 1985 to 9 in Zhenjiang, Jiangsu Province, presided over the convening of the JLS are speed meter appraisal meeting. Through the China Institute of Metrology, Ministry of Machinery Kaifeng flow test center test and Qixiashan Chemical Fertilizer Plant in Nanjing and other users a year of trial operation, the General Assembly that JLS are speed tube
