AvCount is a new laser based particle counter for checking and maintaining the quality of aviation jet fuel throughout the distribution network.

Fuel types include aviation turbine oils, biofuels and biofuel blends, heating oil, gas oil, diesel - automotive and marine, gasoline and kerosine.

DEF STAN 91-91
Seta ‘AvCount’ Particle Counter IP 565 is now included in DEF STAN 91-91 Aviation Jet Fuel Specification, Issue 6 for Certifying Jet A-1. Click here for information about IP 565 in DEF STAN 91-91.

Maintaining Fuel Quality in the supply and distribution systems is a major concern. The potential for particulate (dirt) contamination is high, particularly from:

• Refinery Processing Materials
• Corrosion & Rust in Pipes and Tanks
• Airborne Solids
• Degraded & Damaged Hoses and Filters
• Microbiological Growth

The avcount particle analyser is a rugged and portable instrument specifically designed for testing the particulate content of aviation jet fuel for particles ranging from 4μm to >70μm diameter.

The avcount uses the light obscuration principle, where the fluid under test is passed through a cell comprising a laser and a calibrated sensor. Particles in the fluid cast a shadow onto the sensor, which determines the area / diameter and number of particles in the sample.

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.

Avcount is fully automatic once the particle count test sequence is started. The instrument flushes the cell with sample prior to commencing the measurements. A precise volume of sample is then analysed. The flushing / sample analysing sequences are automatically repeated in accordance with the selected test method.

Results are displayed on the LCD screen in real time and printed out on the integral printer as the test progresses. The results are shown for 6 particle size bands in Particles/ml and ISO Code. Results can be saved to memory for trend analysis of samples, printed out on the integral printer or downloaded to a PC or external printer.

The "Log and Show" software option allows data to be downloaded from the instrument to a PC in different formats and allows the instrument to be fuly controlled and configured from any Windows interface.

• Who should use AvCount?

  Refinery Fuel Quality/Laboratory Personnel testing fuel to DEF STAN 91-91 to release Jet A-1.

  Aviation Fuel QA personnel in laboratory and field testing Deisel Fuel environments benefit from a far superior means of ensuring fast and reliable particulate test results than is currently available.

  Fuel suppliers can provide customers with a more comprehensive and secure ‘fuel cleanliness’ report whilst significantly reducing the effort needed for testing.

  Fuel filter maintenance personnel can more easily identify and isolate any potential problem, supporting reduced maintenance costs and downtime.
  

• 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.
