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:

• Simultaneously detects and differentiates between free water and dirt in fuel.
• 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
• Option to tie into data management systems for automatic reporting of fueling data.
• Full flow analysis.
• No sampling errors.
• Easy installation cable/wiring
• Fully Compliant with EI 1598 Second Edition

U.S. Patent No 7,518,719

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 solid particulates 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
