Description

AFGUARD®

AFGUARD® Electronic Water Sensor (EWS) is leading in aviation fuel condition monitoring. The sensor provides the required assurance that every single liter of fuel delivered to the aircraft is monitored and prevents water from reaching the aircraft by triggering a deadman shut down when it detects water concentrations beyond the configured threshold. AFGUARD® can be used in conjunction with all aviation fuel filtration technologies at aircraft refueling.

The sensor is considered fail-safe and hazardous area (ATEX and IECEx) approved. AFGUARD® is qualified for use as an alternative to Chemical Water Detectors (CWD).

  • Qualified to specification EI 1598 2nd Edition
  • Accepted by Joint Inspection Group (JIG)
  • Recommended by IATA Fuel Quality Pool (IFQP)
  • The sensor system complies with the ISO 13849 standard
  • Required in conjunction with EI 1599 Dirt Defence filter elements
  • Recommended for use downstream of all filtration technologies to verify filter performance 

Features

  • Constant monitoring of aviation fuel quality

  • Cost-effective (cost savings on CWD)

  • High-precision measurement

  • Maximum accuracy through reliable sensor technology and traceable recertification

During fueling, the AFGUARD® provides real-time information on water concentration and will warn of elevated levels of free water in the fuel. The onboard memory storage not only allows for historical records of fueling but can also be configured to communicate real-time fueling information via the internet. Knowing the where and when of your operational fuel quality allows you to optimize your resources and be more proactive in preventing costly downtime.
