1. Advantages and disadvantages of vortex flowmeter

The advantages of vortex flowmeter include reliable structure, wide measurement range, high accuracy, and low maintenance; Disadvantages include the need for density conversion, susceptibility to vibration induced pulley disturbances, and high requirements for flow field uniformity. The specific analysis is as follows: the advantages are that there are no movable parts, the structure is simple and reliable: the vortex flowmeter has no movable parts, and the measuring element has a simple sliding layout, which makes its function reliable, has a long service life, and reduces maintenance needs caused by component wear or failure. Volume flow rate is not affected by thermal parameters: The volume flow rate measured by a vortex flowmeter is not affected by thermal parameters such as temperature, pressure, density, or viscosity of the measured fluid. This means that under different operating conditions, its volume flow rate measurement results are relatively stable and usually do not require separate calibration, simplifying the usage process. Wide range of measuring media: It can measure the flow rate of liquids, gases, or vapors, with a wide range of applications, and can meet the needs of various industrial production scenarios. Small pressure loss: During the measurement process, the pressure loss generated by the vortex flowmeter is small, which helps to reduce interference with the fluid system and lower energy consumption. High accuracy and good repeatability: Vortex flow meters have the advantage of high accuracy, with a repeatability of 0.5%, which can provide relatively accurate flow measurement data, and the consistency of multiple measurement results i

s good. Small maintenance requirement: Due to its simple and reliable structure, the vortex flowmeter requires less maintenance in daily use, reducing the cost of use. Disadvantage: Flow conversion is required: The volumetric flow rate of the vortex flowmeter in operation is not affected by thermal parameters such as temperature, pressure, and density of the measured fluid, but the final measurement result of liquid or steam should be mass flow rate. For gas, the final measurement result should be standard volumetric flow rate. Both mass flow rate and standard volume flow rate need to be converted through fluid density, and it is necessary to consider the changes in fluid density caused by changes in fluid operating conditions, which increases the complexity of calculations. There are multiple factors contributing to measurement errors: uneven flow velocity in pipelines can cause measurement errors and affect the accuracy of measurement results. Inaccurate determination of medium density: The inability to accurately determine the medium density when fluid conditions are changed can also lead to measurement errors. Assumption error in steam measurement: Assuming wet and full steam as dry and full steam for measurement can also cause measurement errors. If these errors are not constrained or eliminated, the total measurement error of the vortex flowmeter will be significant. Poor anti vibration performance: The anti vibration function of the vortex flowmeter is poor, and external oscillations can cause measurement errors and even malfunction of the vortex flowmeter. The high flow velocity impact of the channel fluid will cause additional oscillation in the cantilever of the vortex street generator, resulting in a decrease
