Abstract

The invention relates to an intelligent swing type target flow meter, belonging to the field of liquid measuring devices. The intelligent swing type target flow meter is characterized in that a valve body (2) is provided with a detection hole (6), a target plate (2) is arranged at the detection hole and is hinged with the sidewall of the detection hole through an angle sensor (3) so as to form a swing type target structure, the target plate is adapted with a channel (7) in area, the flow variation of a measuring tube is converted into the swing angle variation of the swing type target, then the switch angle is converted into the angle variation of a magnetic line, and an intelligent transducer (5) is arranged and connected at the output end of the angle sensor (3). The target plate is stressed and rotated on a hinge point by a certain angle, the angle sensor sends out an electric signal and inputs the signal into the intelligent transducer, and the intelligent transducer processes the electric signal into a flow signal for display or output, thereby measuring the fluid flow. The intelligent swing type target flow meter has the characteristics of high sensitivity, high adaptive ability, better measuring effect of the flow of the liquid affected by high viscosity, gas and sand content and the like and is especially suitable for measuring the integrated flow of transmission media in a multiphase pipeline.

Description

technical field [0001] The invention provides an intelligent swing target flowmeter, which belongs to the field of liquid metering devices, in particular to a device for measuring the flow rate of production fluid at the wellhead of an oil field. Background technique [0002] Accurate measurement of single well output flow in oilfield has always been a difficult problem in oilfield production monitoring. The liquid production of a single well is characterized by multi-phase media: there are many unfavorable factors such as a wide range of gas-liquid ratio (0-100%), sand content, strong corrosion, and large changes in medium viscosity, so the requirements for flow metering equipment are high. . Conventional separate and weighing measuring equipment are bulky and labor-intensive, making continuous online measurement difficult. On-line continuous metering flowmeters such as mass flowmeters have high cost and low accuracy, and the industrial application of radial and capacitan...
