APS capacitive fuel gauging consists in 4 probes and a central control unit. By mean of 2 probes per tank, it allows controlling the fuel level and displays the result on digital or analogical display.
Linearity is maintained by programming the tanks into an electronic memory that is used as reference by the micro-controller.
Moreover, signal conditioner integrates a monitoring section that continuously checks probes output frequency, and any deviation of pre-set values triggers a warning signal.
Implantation is quite simple because probes do not require any calibration. Level adjustments are performed on conditioner by 4 potentiometers.
This system is is presently certified and in production.
