2. What are the disadvantages of vortex flowmeter?

1. 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 impact of larger pipe diameter is more significant. 2. Poor adaptability to measuring dirty media. The generating body of the vortex based flowmeter is easily contaminated by the medium or entangled by dirt, which changes the geometric dimensions and greatly affects the measurement accuracy. 3. 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. Vortex flow meters can generally only measure the wide flow rate of fluids in media below 300 ℃.

3. What is the difference between vortex flowmeter and balance flowmeter?

Vortex flowmeter and balance flowmeter are two mainstream instruments in industrial flow measurement, and their core differences are reflected in the following aspects:

1. Differences in measurement principles Vortex flowmeter: Based on the Karman vortex phenomenon, the flow rate is calculated by detecting the alternating vortex frequency generated when the fluid flows through the vortex generator, and the frequency is linearly related to the flow rate.

II. Comparison of Nuclear Structure and Performance

III. Preferred Application Scenarios: Vortex flowmeters are preferred for clean gas/steam volume flow measurement, medium and low temperature environments (such as conventional steam pipelines), and scenarios with limited budgets and low maintenance requirements.

IV. Requirements for installation and maintenance of straight pipe sections: the vortex street needs a longer straight pipe section to stabilize the flow field, while the balanced flow meter only needs the anti-interference ability of the front 3D and back 1D. The vortex street is easily affected by vibration, and the noise of the balanced flow meter is reduced to 1/15. Both instruments have their own advantages, and the actual selection needs to consider the characteristics of the medium, working conditions, and cost.

4. What are the mainstream brands of imported steam flow meters?

Currently, in public information, the mainstream brands of imported steam flow meters mainly cover top manufacturers in Europe, America, and Japan, covering mainstream measurement technology routes such as vortex street, Coriolis, and ultrasonic, and are suitable for steam measurement needs in different industrial scenarios.
