Gas Flow Imaging

Make air flows visible

LaVision’s FlowBOS cameras visualize and monitor air and heat flows in industrial processes without the need for smoke or seeding particles meaning zero contamination.  A simple background imaging technique monitors on-line flows over a wide range of flow scales and flow rates with excellent spatial and temporal resolution.

LaVision offers three FlowBOS camera models for different applications. The FlowBOS SE (Standard Edition) camera is designed for multi-purpose applications and flexible working distances, while the FlowBOS CR (Cleanroom) camera is specifically developed for cleanroom applications and the FlowBOS LD (Large Distance) camera for very large measuring distances and demanding applications with naturally moving backgrounds. The FlowBOS SE and LD cameras are supplied in an IP44 housing with interchangeable lenses, while the FlowBOS CR camera and lens are encapsulated in an easy-to-clean IP67 housing. All cameras feature a detachable tablet for intuitive camera control and an interactive view of the flow.

Visualizing your flow with the FlowBOS camera is as simple as recording a movie: point the flow inspection camera through the flow onto the provided background pattern to reveal flow structure and speed that are not visible by eye.

These extremely versatile camera can be used in a wide range of applications from small scale leak detection, through car interior ventilation, to full room flow behaviour in cleanrooms or for HVAC testing.  Because the approach has zero contaminants it is safe to use in all environments and works residue-free.

System setup is fast and straightforward and can be deployed at short notice and supports on-line process control applications.

Particle-free flow imaging

LaVision’s FlowBOS camera for flow visualization in cleanrooms use an optical active, non-toxic seeding gas avoiding particle contamination. In front of an illuminated background the innovative imaging technique shows exactly the air motion, because the seed gas and air have the same flow properties.

• Particle-free flow visualization in clean and ultra-clean rooms
• Live video recording of the natural air flow
• Air and seed gas show identical flow properties

Direct visualization of thermal flows

LaVision’s FlowBOS cameras detect directly thermal flows in front of an illuminated background. The innovative imaging method is sensitive to heat Schlieren in air flows without the need of any flow seeding.

• Direct visualization of heat Schlieren in air
• Live video recording
• Sensitive imaging technique with large dynamic range
