Detail
VIRA GWX Gas Turbine Flow Meter provides reliable gas flow measurement for industrial applications requiring clear, continuous flow monitoring. The product is available in DN25 to DN400 pipe sizes, with flow ranges from 4 to 6000 m³/h depending on the selected diameter and model code.
The GWX series supports pulse and 4–20 mA output signals for integration with PLC, SCADA, building-management and industrial automation systems. DC24V and battery-powered versions are available to suit different installation and power-supply requirements.
With IP65 protection and explosion-protection configurations available for applicable versions, GWX can be selected for a range of industrial gas-measurement duties. Flow range, pressure loss, body material and output requirements should be confirmed according to the process conditions and selected model.
- Natural Gas and Fuel Gas Lines: Flow measurement and monitoring in industrial natural-gas and fuel-gas applications.
- Industrial Gas Distribution: Monitoring gas consumption and flow conditions in factory gas-distribution networks.
- Compressed-Air and Utility Gas Systems: Flow monitoring in compressed-air and compatible utility-gas lines.
