Reliable Flow Measurement for Liquid, Gas, and Steam Applications
The BWB Instruments Vortex Flow Meter provides accurate, reliable volumetric flow measurement for liquids, gases, and steam across a wide range of industrial process applications. Built with no moving parts and no wearing components, it delivers long-term, maintenance-free performance in demanding conditions. Particularly well suited for saturated and superheated steam measurement in power generation and heat supply systems, the meter is equally effective for compressed air, nitrogen, liquefied gases, flue gas, carbon dioxide, solvents, heat transfer oils, boiler feedwater, and condensate applications.
Available in compact and remote configurations, with connection options including flange, wafer, tri-clamp, thread, and insertion types to suit a broad range of pipe sizes and process conditions.
Benefits
- No moving parts and no wearing components ensure long service life and minimal maintenance requirements across continuous duty applications
- Integrated pressure and temperature compensation delivers accurate steam measurement without external instrumentation, reducing overall system complexity
- Wide fluid compatibility covering liquid, gas, saturated steam, and superheated steam from a single meter design
- High temperature capability up to 350°C makes it suitable for steam and thermal fluid applications in power generation and heat supply systems
- Compact and remote configurations available, with remote type supporting converter display or flow computer display for flexible installation in restricted access locations
- RS485 MODBUS and HART communication for direct integration with plant control and monitoring systems
- Insertion type available for large diameter pipes up to DN2000 without full bore installation
