Description

technical field [0001] The invention belongs to a flow velocity measurement device and a test method, in particular to a two-phase flow flow velocity multi-sensor real-time measuring instrument and a test method. technical background [0002] At present, in engineering, there are many flow rate test instruments and test methods, which can be selected according to the needs of the test. However, in some occasions with limited conditions, such as not allowing to cut off the pipeline, it is not allowed to open a window on the pipeline and it needs to be outside the pipeline. Measurement, or the need for the flowmeter to obtain the average flow rate under the condition of variable flow rate distribution in the pipeline, which undoubtedly brings difficulties to the measurement. At present, some existing test devices and methods, such as pneumatic and computerized, all use a single Although the measurement by sensors can achieve the purpose of real-time measurement, it cannot over...
