Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.Embodiment of the present utility model includes but not limited to the following example.
Flow measurement needs fluid to be in " fully-develop turbulent flow state ", and has a lot of throttling element (such as bend pipe, valve etc.) in industry spot, pipeline, and this results in rate of flow of fluid skewness in pipe, is not suitable for flow measurement.Fluid is after the straight length of 10--15D, and fluid is just in " fully-develop turbulent flow state ", is suitable for flow measurement.For these reasons, cause that existing Ultrasonic Wave Flowmeter straight length requirement is longer.Due to the technical reason of moment sensor and signal processing, it is not suitable for the flow measurement of low pressure, low flow velocity.
