Turbine Flow Meter vs. Vortex Flow Meter?

Turbine Flow Meter vs. Vortex Flow Meter?

Working Principle?

Turbine: Fluid rotates a turbine, with speed proportional to flow rate, detected by magnetic sensors.

Vortex: Based on Kármán vortex street, fluid creates vortices past a bluff body, with frequency related to flow rate.

Suitable Media?

Turbine: Only clean, low-viscosity liquids (e.g., water, diesel) or gases.

Vortex: Can measure liquids, gases, steam; handles high temperature/pressure and particulate matter.

Accuracy & Maintenance?

Turbine: High accuracy (±0.5%~1%) but requires regular lubrication/cleaning.

Vortex: Slightly lower accuracy (±1%~2%), low maintenance, no moving parts.

Installation & Cost?

Turbine: Requires horizontal installation, high straight-pipe needs, low initial cost but higher maintenance.

Vortex: Flexible installation, vibration-resistant, lower long-term cost.

How to Choose??

Turbine?: High precision, clean media, and maintenance-permitted scenarios (e.g., oil, chemical).

Vortex?: Complex media (particles, high temp/pressure), low maintenance, or space-limited scenarios.
