STRUCTURE COMPOSITION AND  MEASUREMENT PRINCIPLE

1.Structure composition

the main body of the device, measuring instruments (mass flow meter, gas flow meter, pressure transmitter, pressure gauge), the device electric thermal temperature control and external insulation system, data acquisition and analysis and processing system, data remote transmission and transmission system (optional).

2.Measurement principle

Liquid from oil well realizes the efficient separation of gas liquid two phase flow through gas-liquid cyclone separator. The gas liquid two-phase liquid level and pressure difference are controlled by the gas-liquid separation controller to ensure that the cyclone separator of gas and liquid separation's effect reaches the best. The gas and liquid after separation realizes accurate measurement of liquid volume, water cut and air volume through mass flow meter and vortex gas flow meter respectively. Field pressure data can be measured by pressure transmitter.

3.Functional features:

1. The measurement method is environmentally friendly and conducive to use and promotion;

2. Wide range of applications. It is suitable for multiphase flow measurement of oil unit, branch line or bus under different working conditions and different medium flow patterns in various complex environments such as land, sea and desert.

3. Adopts the pipeline structure design matching with the process, no pressure device, reliable use;

4. Real-time measurement of liquid, oil, gas, water, temperature, pressure and other production parameters can be achieved;

5. High accuracy of measurement data, obvious comparative advantages;

6. With 24 hours continuous automatic online measurement and tracking description function;

7. Reliable operation, long service life, easy operation, less maintenance, low operating costs;

8. Real-time collection, calculation and analysis of on-site data can be realized, and liquid, gas, water (oil) measurement curves and various production reports can be generated;

9. Can achieve pressure, temperature, liquid and other data abnormal alarm function;

10. Can realize the remote transmission and transmission of on-site data;

11. Used for measuring oil well output unit, branch line or bus in joint station or transfer station;

12. Skid mount structure design, easy to install and change the measuring site.
