What are the disadvantages of vortex flowmeter?

1. Poor anti-vibration performance. External vibration will cause the measurement error of vortex flowmeter, and even it can't work normally. The high-speed impact of channel fluid will cause additional vibration of the cantilever of vortex generator, which will reduce the measurement accuracy. The influence of large diameter is more obvious.

2. The adaptability of measuring dirty media is poor. The generator of vortex flowmeter is easily polluted by medium or entangled by dirt, which changes the geometric size and greatly affects the measurement accuracy.

3. The straight pipe section has high requirements. Experts pointed out that the straight pipe section of vortex flowmeter must meet the measurement requirements in the first 40 days and the last 20 days.

4. Poor temperature resistance. Generally, vortex flowmeter can only measure the fluid flow of medium below 300℃.
