What are the advantages and disadvantages of a vortex flowmeter?

Vortex flowmeters have notable strengths and limitations when measuring conductive media.

Advantages:‌

High structural reliability‌ (no moving parts, reducing mechanical failure risks).

Balanced performance‌ (10:1 turndown ratio, low-pressure loss, energy-efficient).

Strong environmental adaptability‌ (operates in -40℃ to 280℃, vibration-resistant in some models).

Disadvantages:‌

Vibration sensitivity‌ (requires anti-interference models or signal filtering near pumps/compressors).

Low-flow limitations‌ (signal weakens at low velocities, requiring velocity checks or pipe diameter adjustments).

Media impurity sensitivity‌ (risk of clogging with particles, necessitating filtration).

Strict straight-pipe requirements‌ (40D upstream/20D downstream for accuracy).

Selection Tip:‌ For conductive media, prioritize corrosion-resistant models (e.g., Hastelloy electrodes + PTFE liners) and consider split designs for harsh conditions.

Key Takeaway:‌ Optimizing installation and model selection based on specific conditions enhances measurement reliability.
