In the petroleum industry, accurate flow measurement is the core link to ensure production safety, optimize process flow, and control costs. The intelligent vortex flowmeter has become an important measuring tool in oil extraction, refining, storage and transportation due to its high precision, wide range, and strong anti-interference ability.

1、 Technical principle: Accurate capture of vortex precession phenomenon

The upgraded application of the intelligent vortex flowmeter based on the Karman vortex street principle forces the fluid to form a rotating vortex through spiral guide vanes. After the vortex flow accelerates in the contraction section of the Venturi tube, it undergoes a second rotation in the diffusion section due to the backflow effect, forming a stable gyroscopic precession phenomenon. The precession frequency is linearly proportional to the fluid velocity and is not affected by physical properties such as fluid density and viscosity. The built-in piezoelectric sensor can accurately detect the frequency of vortex precession, and after processing by the microprocessor, output standard flow data with measurement accuracy up to±0.2%to±1.5%.

2、 Application scenarios in the petroleum industry

1. Crude oil extraction and gathering and transportation

In oilfield wellhead measurement, intelligent vortex flowmeter can monitor the oil production of a single well in real time, providing accurate data for production scheduling. Its high temperature resistance (up to)200℃）High pressure resistance (pressure rating coverage)1.6MPa-4.0MPa）Its characteristics can adapt to complex underground working conditions. For example, a certain oil field adoptsXX-LUX-150Type flowmeter（DN150, Range150-2250m³/h）Afterwards, the measurement error of a single well±3%drop to±0.8%The annual reduction in measurement losses exceeds ten million yuan.

2. Refining process control

In catalytic cracking, hydrocracking and other units of refineries, this flowmeter is used to measure the flow rate of process gases such as hydrogen and gas. Its wide range ratio (up to)1:20）Can cover the range of process fluctuations, anti vibration design (dual detection technology to suppress pipeline vibration) ensures data stability. Feedback from a certain refining enterprise that the precision of process parameter control has been improved after use40%Improved product yield2.3%.

3. Transportation and Trade Handover

In crude oil pipeline transportation, oil tank storage and other links, intelligent spiral vortex flowmeter provides international standards compliant services（ISO 5167）Trade measurement data. Its built-in temperature and pressure compensation function can automatically correct the gas volume, in conjunction withRS485/HARTThe communication protocol enables remote transmission of data. After the application of a long-distance pipeline project, the dispute rate of measurement has decreased90%Save millions of yuan in dispute resolution costs annually.

3、 Core advantage: Reliable operation under harsh working conditions

Corrosion resistant design: The valve body adopts316LMade of stainless steel or aluminum alloy, suitable for corrosive media such as sulfur and chlorine.

Low power operation: overall power consumption of the machine≤5WSupport internal battery power supply（3.6VLithium ion battery) or external connection24V DCMeet the needs of unmanned stations.

Anti theft function: The header password protection can prevent parameter tampering, and the historical data storage function ensures traceable measurement.

4、 Technological development trends

With the intelligent upgrading of the petroleum industry, intelligent vortex flowmeters are integrating with the Internet of Things（IoT）Edge computing and cloud data analysis. For example, a new type of product already has predictive maintenance capabilities, which monitor the health status of the equipment in real-time through vibration sensors and provide early warning of potential failure risks.

The intelligent vortex flowmeter has become the choice for flow measurement in the petroleum industry due to its technical reliability, application flexibility, and data accuracy. Its continuous technological iteration and scenario deepening are driving the development of the petroleum industry towards greater efficiency and safety.
