Problems solved by technology

However, the existing calibration method and calculation output of the permanent magnet vortex flowmeter are relatively simple, and only output the flow rate of the conductive measured medium solution related to the signal vortex frequency, and then obtain the calculated output and the measured conductive medium solution. Flow rate-related volume flow, total volume and other engineering parameters, however, the permanent magnet vortex flowmeter cannot output the gas-liquid mixed conductivity measurement medium solution of the bubble content in the flow rate, the total number of bubbles and other parameters

[0003] The working principle of the gas-liquid mixed flow vortex flowmeter is basically the same as that of the permanent magnet vortex flowmeter. The gas-liquid mixed flow vortex flowmeter can be used in the fields where the permanent magnet vortex flowmeter can be applied. In addition, the gas-liquid mixed flow vortex flowmeter can output the same engineering parameters as the permanent magnet vortex flowmeter, and it can also output the flow rate of the gas-liquid mixed conductive conductive medium solution, the total number of bubbles Therefore, the gas-liquid mixed flow vortex flowmeter can be used in some special occasions, and these occasions are widely used in petrochemical and urban water supply pipelines. However, the existing calibration devices cannot provide gas-liquid mixing. The measured medium solution of the type conductivity cannot meet the requirements of product calibration of the gas-liquid mixed flow vortex flowmeter. Therefore, it is necessary to propose a new device system and control method to solve the above technical problems.
