In aviation, the safety and efficiency of refuelling procedures depends on the delivery of clean and dry fuel to aircraft. Contaminated fuel poses significant risks, from operational inefficiencies to incidents. Differential pressure (dP) monitoring is a vital process in ensuring fuel quality.
This article covers:
Differential pressure is a clear indicator of the status of the filter element inside the vessel of the refuelling system. As filters accumulate contaminants, the pressure difference across them increases. Exceeding the allowed threshold can result in decreased filtration efficiency, allowing dirt, water, or filter media to pass through.
Contaminants in aviation fuel can compromise aircraft operations, potentially causing catastrophic safety issues. To prevent such risks, monitoring dP during refuelling is crucial. The ability to track and respond to dP changes ensures the fuel delivered is of the highest quality, safeguarding flight safety.
VEGA T2 offers the possibility of interfacing to the density meter over Modbus (depending on the densitometer model) so that it can acquire in real time the measurement of the mass.
Managing differential pressure effectively involves real-time monitoring and quick response to deviations.
Advanced systems are therefore required to enable operators to:
The VEGA T2 flow computer is designed to enhance the monitoring and management of differential pressure, thus ensuring compliance and safety.
When a differential pressure transmitter is installed across the filter, it generates a signal – typically over 4/20 mA – which is proportional to the dP measured value and it can be sent to the VEGA T2 flow computer.
Key features of VEGA T2 to monitor differential pressure are:
