The uncertainty analysis of liquid flow meter line detection device 液体流量计在线检测装置不确定度分析
The liquid flow meter developed by TRICM is in fact a closed loop measurement system. 我们所研制的这种测试仪,实际是一种闭环测试系统。
An ultrasonic Doppler liquid flow accumulative calculator is developed on the basis of the characteristic constant calculated by the Doppler flow-meter equation derived through refractive ultrasonic and phased-array di-rect contact detection of cylinders of specific diameter. 通过对特定管径,用折射或相控阵水浸式探头检测,推导出流量计的多普勒方程,并由此计算出仪表常数,研制了流量计积算器。
The phase separation phenomena in helically coiled tube multiphase flow is substantial to design innovative curved pipe separator. Particle size and concentration profiles in the liquid film of air-water-sand three-phase flow through a separator prototype were measured using Malvern Particle Meter. 为了深入认识螺旋管多相流相分离现象,并为新型螺旋管除砂器设计提供指导,本文应用马尔文粒度仪,测量了螺旋管气水砂三相流底部水平段液膜中的颗粒浓度和粒度分布。
A liquid flow meter 一种液体流量计
The problems shall be solved as the sulfuric acid is not added into the granulator pipe reactor for lack of sulfuric acid pump with high head and small flow, the unbalanced scrubbing liquid as well as the big error of liquid ammonia flow meter. 因无合适的大扬程小流量硫酸泵,造粒机管式反应器中尚未实现加硫酸,以及洗涤液不平衡、液氨流量计计量误差大等是有待解决的问题。
