Spray Analysis Software - EnVision: Patternate

Spray analysis software for non-intrusive, automatic spray pattern & plume geometry analysis. The software is suitable for characterisation of a wide range of liquid plumes and aerosols including metered dose inhalers, nasal devices, fuel injectors, paint sprays, agricultural / pesticide delivery systems, fire suppression.

Envision spray analysis provides measurement of:

  • Cone angle Plume geometry
  • Cone / Plume width
  • Cone / Plume height
  • Ellipticity of pattern
  • Size of Pattern
  • Event Duration

For spray characterisation the user should provide an image or high speed movie of the appropriate spray cross-section. The software then performs a number of measurements:

Cone Angle / Plume Geometry measurement


EnVision performs characterisation on a single image or can combine a sequence of images of the spray to form a composite image and then measures the cone angle, direction, plume geometry and other user-definable parameters.

Spray Pattern Measurement


The spray analysis software can perform the analysis on a single image or a combination of images. An ellipse or number of ellipses are then fitted to the image and all the key parameters of the ellipse reported.

Spray Duration Measurement

The analysis is performed on a series of images from a high speed movie and a time history of the event created.
