摘要（英）：

The invention provides a tube-type oil well vapor-liquid two-phase flowmeter and a measuring method thereof. The tube-type oil well vapor-liquid two-phase flowmeter comprises a first measuring pipe, a second measuring pipe, an inlet three-way valve, an outlet three-way valve, a first connecting pipeline, a second connecting pipeline, a first differential pressure transmitter, a second differential pressure transmitter, a third differential pressure transmitter, and a fourth differential pressure transmitter. The first measuring pipe and the second measuring pipe are connected with a liquid supply pipeline through the inlet three-way valve. The first measuring pipe and the second measuring pipe are connected with a liquid discharging pipeline through the outlet three-way valve. A first connecting line is connected with the top of the first measuring pipe. A second connecting line is connected with the top of the second measuring pipe. The first differential pressure transmitter and the second differential pressure transmitter are connected with the first measuring pipe. The third differential pressure transmitter and the fourth differential pressure transmitter are connected with the second measuring pipe. The tube-type oil well vapor-liquid two-phase flowmeter and the device using the measuring method are simple in structure, a measuring sensor has no moveable component, and signal obtaining is convenient and accurate, and is easy to realize.
