| 6. | On the other hand , the electrostatic sensor has no reaction to the solid particulate accumulated in the pipeline , so the electrostatic sensor can obtain higher precision in the concentration measurement than other traditional mass flow rate measurement techniques 另一方面,由于静电传感器对沉积在管道中固体颗粒不产生反应,因此,与其他传统的质量流量测量技术相比,静电传感技术能够在浓度测试方面达到更高的精度。 |
| 7. | In this paper theoretical and experimental studies are carried out on cross correlation techniques using electrical capacitance sensors applied to non - intrusive restrictive velocity and mass flow rate measurement in a cyclone separator . the mass flow rate is determined from two parameters , namely the solids velocity and the volumetric concentration 本文同时将电容层成象和相关技术结合,采用双层电容传感器测量了旋风分离器料腿中固体颗粒的断面浓度分布,同时得到了固体颗粒沿轴向和周向的二维速度。 |
| 8. | With the experiment , the author believes that electrostatic transducer technology has several characteristics as the new means of mass flow rate measurement technique : its structure design is very novel and can be prone to be installed , it is more suitable for the measurement on the mass flow rate of the coal particulate in larger caliber pipelines and has higher delicacy in the measurement on both dilute and dense phases 通过实验,作者认为静电传感技术作为一种新兴的质量流量测量技术具有以下特点:静电传感器结构设计新颖,易于安装,适合于大口径管道中煤粉颗粒的质量流量测量,对稀相及浓相测试均具有较高的灵敏度。 |
| 9. | So anew type of measurement and instrumentation is badly needed and developed which is suitable for non - centralized and stationary measurement based on this idea , this study take the new type of oilavater two - phase flow measurement and instrumentation development as the basic goal , cany out some theoretic exploration of measurement in order to improve oil / water two - phase flow well logging method and technique , and try to accomplish bom holdup and total flow rate measurement with one equipment simultaneously so as to push forward development of oilavater two - phase flow well logging 本文正是基于这一思想,以开发新的油水两相流测试仪器为目标,进行先期的测量理论探索,试图从原理上改进油水两相流测井方法和工艺,实现利用同种电学敏感原理同时完成持率和总流量的测量,推动油水两相流测井技术的发展。 |
