Vortex Flow Meters for Steam, Gas & IIoT Efficiency
Vortex Flow Meters: Smart Solutions for Modern Process Efficiency
Cost-effective, multi-purpose measurement for steam, gas, and liquid applications
As energy costs rise and digital transformation accelerates, vortex flow meters provide a reliable solution for measuring steam, gas, and liquid flows in industrial processes. Their robust design and digital capabilities make them ideal for modern energy management and automation systems.
With no moving parts and native digital output, vortex meters deliver long-term reliability while seamlessly integrating with industrial IoT (IIoT) platforms for smarter process control.
Measurement Principle
Vortex flow meters operate on the Kármán vortex street principle, where a bluff body (shedder bar) placed in the flow stream creates alternating vortices downstream. The vortex shedding frequency is directly proportional to the fluid velocity.
Key Performance Characteristics
- Typical accuracy: ±1% of reading for liquids, ±1.5% for gases/steam
- Turn down ratio: 10:1 (liquids), 15:1 (gases)
- Pressure rating: Up to 100 bar (1450 psi)
Technical Advantages
Maintenance-Free Operation
With no moving parts in contact with the process fluid, vortex meters require minimal maintenance compared to mechanical flow technologies. Typical service life exceeds 10 years in standard applications.
Steam & Gas Measurement
Specially designed models handle saturated and superheated steam up to 400°C (752°F), making them ideal for boiler and steam distribution monitoring. Also effective for compressed air and natural gas applications.
Digital Integration
Native pulse/frequency output simplifies connection to control systems. Advanced models offer Modbus, HART, or Foundation Fieldbus protocols for seamless integration with SCADA and IIoT platforms.
Cost Efficiency
Lower total cost of ownership compared to other technologies, with typical payback periods under 12 months in energy monitoring applications due to reduced maintenance and installation costs.
Industrial Applications
Steam System Optimization
As industrial energy costs rise, vortex meters help plants monitor steam consumption, identify leaks, and optimize boiler efficiency - typically reducing energy waste by 5-15%.
- Temperature range: -40°C to 400°C (-40°F to 752°F)
- Materials: 316L stainless steel standard, alloy options available
- Installation: Requires 15D upstream and 5D downstream straight runs
