AVCOUNT


Advanced Laser Based Particle Counter
  • Aviation turbine fuels (Jet A & Jet A-1)
  • Biofuels and Biofuel blends
  • Heating oil, Gas oil
  • Diesel - Automotive and Marine
  • Gasoline and Kerosine.

 

AvCount is a new laser based particle counter for checking and managing the quality of fuel from Refinery to wing tip.

  • Fast, fully automatic, ‘plug and go’ operation
  • Particle size 4μm to >70μm
  • Cumulative & distributive particle numbers
  • ISO 4406: 1999 codes
  • Uses “Straight from the Bottle” samples
  • Precise and reliable results
  • Laboratory or portable field use
  • Calibration traceable to ISO 11171
The AvCount particle analyser is a rugged and portable instrument specifically designed for testing the particulate content of fuel for particles ranging from 4μm to >70μm diameter.

AvCount is fully automatic once the test sequence is started. The instrument flushes the cell with sample prior to commencing the measurements. Flushing and sample analysing sequences are automatically repeated in accordance with IP 565/08. Results are displayed on the LCD screen in real time and automatically averaged. The results are shown for 6 particle size bands in particles/ml and the corresponding ISO Code is also displayed. Results can be saved to memory for trend analysis of samples, printed out on the integral printer or downloaded to a PC for further analysis.

Precise checks for particulate contamination
Sampling and measurement is simple; fuel is drawn from a sample container or directly from the supply line. AvCount has a 10 bar standard pressure rating or can sample up to 315 bar line pressure using the optional pressure reducing system. An integral pump automatically draws the sample through an internal measuring chamber, removing the need for an external sampling pump.

Sample presentation for measurement
Correct sample presentation is key to achieving consistent results. The samples must be gently rotated to ensure an even dispersal of particulate matter, but care must also be taken to avoid the creation of air bubbles that may distort the results. Seta offer two specifically designed tumbler systems for the purpose of providing a uniform representative sample, minimising the risk of creating these bubbles.
Benchtop system
Designed for up to 500ml bottles, available with optional fittings to allow a range of bottle types.
Floor Standing
Designed for 5 litre IATA cans. IATA cans are both heavy and bulky and this unique tumber allows safe and consistent rotating of the sample
