吉林省通化县化肥厂将西德公司生产的DN25旋涡流量计用在合成工段的液氨计量上.DN25流量计利用卡曼涡流原理,通过检测涡流的频率来测量流量的变化值,它具有指示流量的瞬时值和累积流量的功能.该套仪表主要以DV630(测量接收器)、DMV6320(转换器)为核心,配以安全障栅、F574(计数器)、电流指示仪等构成成套仪表.该流量计安装注意以下几点:1.选择的工艺管径应与DV630接收器一致,若不相同,需计算两管内部截面积的比
Tonghua County, Jilin Province, fertilizer plant will West Germany produced DN25 vortex flowmeter used in the synthesis of liquid ammonia measurement.DN25 flow meter using Karman vortex principle, by detecting the frequency of eddy current flow changes, it has an indication Instantaneous flow rate and cumulative flow of the function of the instrument mainly DV630 (measurement receiver), DMV6320 (converter) as the core, together with the safety barrier, F574 (counter), current indicator, etc. constitute a complete set of instruments. Flowmeter installation note the following: 1. The selected process diameter should be consistent with the DV630 receiver, if not the same, need to calculate the ratio of the two internal cross-sectional area
