UAV Propulsion Tech Post #30 – UAV Engine/Fuel Sensors

I started representing Reventec, Ltd. out of the UK to market their advanced engine and fuel sensors into the UAV market.  Reventec is well known in the Formula 1 racing industry and uses some pretty high tech sensor technology to measure engine and fuel parameters.  UAV’s are starting to use these high tech sensors to measure fuel level, fuel flow, engine speed, engine temperature and throttle position.  The racing industry drove the design for high reliability and accuracy which are the  same requirements for UAV applications. I thought I would focus my blog on these solutions that are available by Reventec, Ltd.  These sensors can interface with the UAV flight computer to monitor the propulsion and fuel delivery parameters: fuel level, fuel flow, oil level, cylinder head temperature, engine rpm and throttle position.

LIQUID LEVEL SENSING (FUEL OR OIL):

Capacitive level sensing technology works by simply measuring the permittivity difference between air and the fluid level change between the probe’s electrodes.  An electronic circuit is used to measure this change in liquid level and the sensor output changes from 0.25V (empty) to 4.75V (full).   These sensors are designed for 12V but can handle supply voltages from 6V to 31V, they are resistant to several fluids, can be used in environments from -40C to +125C and have an ingress protection rating of IP67.

EcoSense Liquid Level Sensor

EcoSense is a next-generation solid-state capacitive sensor, capable of continuous level measurement in all common liquid types. The modular sensor allows for a wide range of mounting options with the use of a custom or stock mounting adaptor.

  • Solid-state, continuous liquid level sensing
  • ±2% full scale accuracy
  • No measurement dead-band
  • FIA homologation certified
  • 0-5V Configurable Output
  • Customisable Length
  • Multiple mounting arrangements available
