Fuel System Maintenance Equipment
Fuel system maintenance equipment includes test sets for the aircraft fuel quantity indicating system (FQIS). Most systems measure fuel level with capacitance probes; Barfield groups them as AC capacitance and DC capacitance systems, named after the signal the fuel system amplifier processes [1]. A fuel quantity tester checks insulation of wiring and probes, measures tank and probe capacitance, simulates capacitance to test indicators and amplifiers, and bench-tests remote indicators [1]. Novatelia sources selected FQIS test sets by RFQ for operators in Oman and qualified GCC projects.
Applications
- Insulation testing of FQIS wiring and probes [1].
- Fuel tank and individual probe capacitance measurement [1].
- Capacitance simulation to test indicators and amplifiers [1].
- Bench testing of remote indicators [1].
Equipment types
- AC capacitance test sets, e.g. Barfield DFQ40K [1].
- DC capacitance test sets for diode-rectification probe systems, e.g. Barfield DC400A with adapter modules [1].
- Aircraft-specific interface harnesses [1].
How to select equipment
- AC or DC capacitance system on your fleet [1].
- Interface harnesses or adapter modules for each aircraft type [1].
- Calibration certificate and recall support for your quality system.
Customer types
- Airline line and base maintenance
- Avionics and electrical shops
- Helicopter operators
Good practice
- Fuel tank work follows the aircraft maintenance manual and fuel-tank safety procedures; test sets must be suitable for use on the aircraft fuel system.

Oman & GCC support
For fuel system maintenance equipment, Novatelia handles sourcing, quotation and delivery coordination from Muscat for Oman customers and on a project basis for other GCC countries; see Aviation supply in Oman. Novatelia does not claim local OEM service centres or civil aviation authority approvals.
Frequently asked technical questions
What is the difference between AC and DC capacitance systems?
The names come from the type of signal processed by the fuel system amplifier; DC systems use diode-rectification probes [1].
Can one tester cover several aircraft types?
Yes, with the correct interface harnesses or adapter modules for each type [1].
