Home / Products / FLXscan Tomography

The FLXscan planar drop sizer simultaneously measures the extinction and fluorescence intensity from a spray at three view angles with six linear arrays. These measurements are deconvoluted to provide full planar drop sizes and surface area densities n the spray. The spray measurements are obtained a frequency of 1,000 Hz enabling the characterization of fuel injectors and consumer nozzles.

Three axis system for sprays up to 250 mm in diameter
Single axis system for sprays up to 250 mm

  • Measures spatially resolved planar Sauter Mean Diameter in spray
  • Simultaneously provides full planar drop surface areas
  • Characterized liquid sprays with Fluorophore
  • Different sizes for sprays from 25 mm to 250 mm

Quality audit of:

  • Fuel delivery nozzles for aero-engines
  • Agricultural nozzles used in various applications
  • Nebulizers, metered dose inhalers, and nasal sprays
  • Consumer aerosol dispensers for fragrances, cleaners, and insecticides
