湿气流量测量是一个活跃的领域，具有广泛的研究背景，仍然是一个现代的挑战。湿气流动条件的含义在碳捕获和储存（CCS）管道中没有什么不同。与湿气流相关联的复杂流态使得难以精确地计量气相的流率。一些传统的单相流量计，如科里奥利，孔板，超声波，V型锥，文丘里管和涡流已经过测试，通常伴随着特殊的建议。通常，需要在特定条件的一定范围内有效的相关方程来校正流量计的响应。本文介绍了一种最先进的平均皮托管用于湿CO2气体流量测量的适用性和性能的研究。本文介绍了具有流动调节翼的均速管（APT-FCW）在测量纯CO2和干CO2流量时的实验结果，测量误差在± 1%以内。但在湿气体条件下，APT-FCW传感器的测量误差可达±25%，当液体含量高达20%时，采用适当的校正方法，测量误差在±1.5%以内。
The flow measurement of wet-gas is an active field with extensive research background that remains a modern-day challenge. The implication of wet-gas flow conditions is no different in Carbon Capture and Storage (CCS) pipelines. The associated complex flow regime with wet-gas flow makes it difficult to accurately meter the flow rate of the gas phase. Some conventional single-phase flowmeters like the Coriolis, Orifice plate, Ultrasonic, V-Cone, Venturi and Vortex have been tested for this application, usually accompanied with special recommendations. Often, a correlation equation valid within a certain range of specific conditions is required to correct the response of the flowmeter. This paper presents investigations into the suitability and performance of one of the most advanced averaging pitot tubes for the flow measurement of wet CO2gas. The averaging pitot tube with flow conditioning wing geometry (APT-FCW) was studied and experimentally assessed in earlier work for the flow measurement of pure and dry CO2within an error of ±1%. Under wet-gas conditions, however, the APT-FCW sensor is found to give an error of up to ±25% and within ±1.5% after appropriate correcting solutions are applied for a liquid fraction of up to 20%.
