VCA® and VCA-CV: Final Protection from Contaminated and/or Wet Fuel
Product Description
The VCA® (Velcon Contaminant Analyzer) uses laser sensing technology to insure that the fuel being loaded onto commercial airliners is clean and dry. In the event of wet or dirty fuel (or both), the system can act as a final stage quality check downstream of last filtration, shut down the fueling operation, and alert the user with
a minimal amount of contaminated fuel reaching
the plane.

VCA® Features:
- Differentiates between free water and dirt in fuel: detects both simultaneously.
- Modular user readout, showing
free water content in ppm (parts per million) and particulate
solids in mg/l (milligrams per liter.)
- Flow sensor operates VCA
only during fueling*
- Visual alarm and deadman
cutoff switch
in case of dirty or wet fuel (includes a key operated system
bypass.)
- Option to tie into data management systems for automatic
reporting of fueling data.
- Automatic calibration*
- Optional data logger to capture all fueling data on a compact
flash card.
- Full flow analysis.
- No sampling errors.
- Easy
installation cable/wiring
* U.S. Patent No 7,518,719 (Click here to view Velcon's press release, 4-24-09)
Benefits:
- Completely transparent and contained operation: initiation
of operation by internal flow switch and “in-situ” calibration
that does not require removal for service
- Ability to differentiate
between water and particulate solids for proper contamination alert levels and a more efficient
diagnosis of contamination source
- Automatic shutdown will
stop flow as soon as wet or dirty fuel is sensed

VCA-XX Part Number Breakdown:
where XX can be any of the following:
03 – 3” (78 mm) diameter
04 – 4” (102 mm) diameter

VCA-CV - Fuel Quality Assurance System
2008 Energy Institute Innovation Award Finalist
For the VCA-CV,the VCA® instrument is integrated into the outlet side of the CLA-VAL flow control valve body. Due to the unique features of the CLA-VAL flow control valve, the VCA® can be automated to begin function when the flow control valve is actuated (when flow starts). If the concentration of either free water or solid particles exceeds quality limitations, the VCA can automatically stop flow at the control valve. The VCA has been extensively field tested, and the CLA-VAL control valve is an industry standard. The combination of these two products into one will extend the versatility and flexibility to any type of fuel system.
