1. Who knows the advantages and disadvantages of vortex flowmeters?

No instrument is perfect and has certain limitations in product performance, and vortex flowmeters are no exception. The advantages and disadvantages of vortex flowmeter are: 1. Vortex flowmeter has no movable parts, simple measuring element structure, reliable performance, and long service life. 2. Vortex flowmeter has a wide measurement range. The range ratio can generally reach 1:10. The volumetric flow rate of a vortex flowmeter is not affected by thermal parameters such as temperature, pressure, density, or viscosity of the measured fluid. Generally, there is no need for separate calibration. It can measure the flow rate of liquids, gases, or vapors. 4. It causes minimal pressure loss. 5. It has high accuracy, a repeatability of 0.5%, and requires minimal maintenance. Disadvantages of Vortex Flow Meter

1. The volumetric flow rate of vortex flow meter in working state is not affected by thermal parameters such as temperature, pressure, 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 must be converted by manually selling fluid density, and the changes in fluid density caused by changes in fluid operating conditions must be considered. 2. The main factors causing measurement errors in flow rate are measurement errors caused by uneven pipeline flow velocity; Unable to accurately determine the medium density when fluid conditions change; Assuming wet saturated steam as dry saturated steam for measurement. If these errors are not limited or elimin Vortex flowmeter

ated, the total measurement error of the vortex flowmeter will be very large. 3. Poor anti vibration performance. External vibrations can cause measurement errors in vortex flowmeters, and even prevent them from functioning properly. The high flow velocity impact of the channel fluid will cause additional vibrations in the cantilever of the vortex generator, resulting in a decrease in measurement accuracy. The influence of larger pipe diameter is more significant. 4. Poor adaptability to measuring dirty media. The generating body of the vortex flowmeter is easily contaminated by the medium or entangled by dirt, which changes the geometric dimensions and greatly affects the measurement accuracy. 5. The straight pipe section requires high requirements. Experts point out that the straight section of the vortex flowmeter must ensure the first 40D and the last 20D to meet the measurement requirements. 6. Poor temperature resistance performance. Vortex flow meters can generally only measure fluid flow rates of media below 300 ℃. Zmjt10
