Velcon’s VCA and icount products use technology based on proven principles of light obscuration, refraction and light scattering. Particle counters, also known as Automatic particle counters (APC) measure the size and concentration of contaminants in fluids.

APC’s have been widely used for many years in condition monitoring. However, it is only recently that APC’s have become flexible enough to enable the instruments to be taken out of the laboratory and used on-line in order to obtain the most credible form of results. Portability also allows for use over a wider range of applications and situations.

Parker has developed technology to ensure the APC was able to test a sample without the conventional laboratory technique which requires dilution - a practice that would have been simply impossible with a portable unit.

The VCA is an on-line monitoring system with the capability of detecting solid and liquid contaminants and can be configure to shut off flow when contaminant levels exceeds your define threshold. In addition, the telemetry option allows for remote monitoring on a global scale via cellular network.

The icount particle analyzers are designed for monitoring and testing of solid contaminants. Velcon offers four types of system depending on your application needs. Except for the icountPD, all products can be used as an on-line monitoring system or be completely portable while providing real-time or immediate results with the capability of storing of test results.

Measures water content of Jet Fuel.
The test requires two simple steps. First, a measured sample of fuel is passed through a paper pad that is treated with sodium fluorescein on its upstream surface. Second, the pad is compared with a fluorescing standard in ultraviolet light. Water droplets that are smaller than the eye can see will cause the sodium fluorescein to fluoresce. The degree of fluorescence is greater for increasing amounts of water in the fuel.

The AQUA-GLO^® Kit employs this unique approach in the determination of the degree of flouorescence (or water content). A single, permanent fluorescing standard is positioned under a photographic-type iris diaphram which can be opened or closed to increase or decrease the amount of ultraviolet light.

To determine water content, the operator merely adjusts the diaphragm lever arm until the fluorescing standard and the test pad show equal brightness in the ultraviolet light. This balance is reached when the zero centering ammeter reads ZERO. The amount of water is read in parts per million (ppm) on the diaphragm lever arm scale which has been pre-calibrated in the factory. The scale numbers range from 1 to 12. These numbers are in parts per million (ppm) if the test sample of fuel that flowed through the pad was 500 ml. However, if water content is as great as 60 ppm, the test sample can be reduced to 100 ml. When a 100 ml sample is taken, the operating instructions explain that the scale reading must be multiplied by 5 to obtain the water content in ppm.

The Series V Aqua-Glo^® was introduced in 2005 with an entirely new power supply. This power supply is external, automatically switches to work with either 120vac or 220vac, 50/60hz.. The water detector pads that are used in the AQUA-GLO^® Kit are produced in compliance with MIL-D-81248 (WP) with the exception that the diameter is 25 mm. Each pad is packaged in an air and moisture-proof envelope.

The AGUA-GLO^® Kit pad holder is designed for ease in sampling. Fittings are available for several different methods of taking samples. For example, the standard fitting permits direct connection to a quick disconnect. Another fitting allows the sample to be drawn through the test pad with a syringe.

The AQUA-GLO^® Kit is based on a technique developed by the U.S. Navy for accurate field determination of the free water content of jet fuels. Unlike the Navy equipment, the AQUA-GLO^® Kit requires only one fluorescing standard and is instrumented to eliminate human error.

An outstanding feature of the AQUA-GLO^® Kit is permanency of the fluorescing standard. Extreme care has been taken in perfecting a standard that will not deteriorate with age.

The kits pictured here have become standard in the industry for obtaining test samples of jet fuel. With more than 250,000 in service, they have proved to pay for themselves by saving countless hours of downtime because accurate contamination test results are obtained the first time.

In the past, thousands of work hours have been wasted and fueling facilities have been shut down simply because the sampling tap was contributing dirt during the sampling period. Rusty pipe threads, steel gate valves and collections of reducing bushings that never are subjected to fuel flow, except when a contamination test is to be run, have been found to be a prime cause of poor color results when tests are performed to ASTMD2276. Flushing does not clean normally stagnant steel fittings.

The probe penetrates through the pipe coupling that is welded to the pipe. There is no possibility of rust and dirt, that usually collects in stagnant pockets (such as welded coupling), reaching the test membrane.
Non-ferrous materials are used in our kits; All passages are small (0.25 inch pipe size) to insure that there will be enough velocity during the flushing cycle to carry away any sediment that may have collected.

Note: Kit #7T allows pressure sensing and sampling independently through one pipe connection. The probe penetrates all the way through the tee. Sample will never contact the tee. The branch on the tee is for a pressure gage connection; it senses pressure on the outside of the probe tube.

The GTP-144 Probe, at 2.25 inches, is made to reach the center of a 4.0 inch pipe but can be used in any pipe of 2.0 inches or more. The threads on the probe are both 0.25" NPT male (use reducing bushing to come down to this size). Custom probes may also be ordered.

The Mini Monitor Kit Mark II is used to test aviation fuel for particulate contamination using the procedures described in ASTM D2276. A measured volume of fuel is passed from a flowing pipe directly through a 0.8 micrometer membrane. The plastic monitor holding the membrane is placed in an aluminum housing. Dirt particles are caught on the membrane which can be visually color-rated or weighted for a gravimetric rating.

In the new Mark II design, the inlet fuel to the plastic monitor is dispersed laterally to insure a more uniform distribution of particles over the entire surface.

The Mark II version has the unique advantage of eliminating the white spot in the center of the membrane (see photograph below, a membrane not used in the Mark II Kit), which is caused by the fuel entering the monitor at a high pressure. The drawing found on the GTP-172H item page shows how the fuel is dispersed laterally, avoiding the jet effect.

The Mini Monitor Kit is built with stainless steel parts, ensuring that the test sample comes in contact only with stainless steel before reaching the filter membrane. This Kit was developed specifically for aircraft fuel testing with standard field monitors, and weighs only 4 pounds with carrying case.

GTP-172 includes*:
Carrying case, assembled housing and selector valve, bonding and grounding hose assembly, GTP-165 syringe, sampling kit GTP-5, GTP-2099 tweezers, GTP-1074-1 color rating booklet, GTP-1985-6 plastic monitors (6), and GTP-1267 Mini Envelopes (15).

Detect Free Water in Aviation Fuel

FEATURES
• Easy to Use – Automatically controls the sample size. Simple evaluation by color comparison.
• Shelf Life – One year shelf life. Refer to date on box.
• Responds Consistently – Responds consistently in a wide variety of aviation jet fuels.
• Carefully Controlled Quality – Manufactured by Parker Velcon Filtration to strict quality control specifications.

DESCRIPTION
The Parker Velcon Hydrokit® is an effective “Go, No-Go” field test designed to periodically check for free water, which is removed to ppm levels by properly operating filter/separators, Aquacon®, and monitor vessels. Samples are normally taken downstream of the vessel, but they can also be taken at other points in the fuel distribution system.

The Hydrokit® is designed to indicate free water in excess of 30* ppm by changing the powder contained in the sample tube to a pink color. Thirty ppm is generally accepted as the maximum amount of water permissible when fueling aircraft. The Hydrokit® is designed for “fail-safe” operation, with false negative readings unlikely. Almost any error in performing the test will indicate the presence of wet fuel. If the sample indicates the presence of excessive water, it is always a good practice to repeat the test on a second sample.

Detect Surfactants in Aviation Jet Fuel

FEATURES
• Easy to Use/Rapid Results - Test done in the field, no need to wait for lab results.
• High Degree of Accuracy - Repeatability to within ±3 dynes/cm when compared to the ASTM D971 ring method.

DESCRIPTION
The patented* VELCON SWIFTKit is the first practical device to determine the Interfacial Tension (IFT) of aviation jet fuel in the field. The IFT value is a general indication of the surfactant (surface active agent) level in fuel; higher IFT values indicate lower surfactant levels. Surfactants can disarm coalescer elements, which could allow excess water downstream and into the aircraft.

APPLICATIONS
The SWIFTKit can be used for general quality checks on fuel during transfer and transportation, and particularly for receipts into airport storage. The SWIFTKit is especially useful to determine the condition of clay treatment cartridges by comparing the upstream and downstream IFT values. An increase in IFT value shows that the clay is still effectively doing its job of removing surfactants.

Each SWK1 SWIFTKit box includes:
20 sample SWIFTKit tubes
5 flush tubes
1 wide mouth glass sample jar
1 needle holder assembly
1 procedure sheet
1 illustration of procedure sheet
1 safety and MSDS sheet
