| 本研究开展了S型皮托管、超声波流量计在两条同等规模水泥熟料试点生产线的对比试验，对比了单声道超声波、S型皮托管流量计在1#试点生产线上流速监测数据，分析了两种技术所测数据的相对偏差、相关性；对比了多声道超声波、单声道超声波、S型皮托管流量计在2#试点生产线上流速监测数据，分析了三种技术所测数据的相对偏差、相关性；利用三维皮托管手工监测方法，评估了1#试点生产线单声道超声波、S型皮托管流量计所测数据的准确度、精密度，评估了2#试点生产线双声道超声波、单声道超声波、S型皮托管流量计所测数据的准确度、精密度；最后，对超声波、S型皮托管流量计的优缺点做了分析。 |
| 英文摘要: |
| This article proposes a comparative experimental plan of S-type pitot tube and ultrasonic flowmeter in two pilot production lines of cement clinker with the same production scale. It compared the flow rate monitoring data of monaural ultrasound and S-type pitot tube flowmeter on the 1# pilot production line，and analyzed the relative deviation and relevance of data measured by two techniques；It compared the flow rate monitoring data of multi-channel ultrasound, monaural ultrasound, and S-type pitot tube flowmeter on the 2# pilot production line，it analyzed the relative deviation and relevance of data measured by three techniques，using the manual monitoring method of three-dimensional pitot tube， the accuracy and precision of the data measured by monaural ultrasound and S-type pitot tube flowmeter on the 1# pilot production line were evaluated，the accuracy and precision of the data measured by the dual channel ultrasound, single channel ultrasound, and S-type pitot tube flowmeter on the 2# pilot production line were also valuated. Finally, the advantages and disadvantages of ultrasonic and S-type pitot tube flow meters were analyzed. |
