We have proven experience with sensitive capacitance measurements and intimate knowledge of fuel tank safety, electromagnetic interference and low signal to noise ratios. We consider the system requirements for sampling and filtering to ensure that accurate fuel quantity information is available to other aircraft systems. This domain knowledge ensures that out Fuel Data Concentrators perform reliably in any aerospace application.
