Reventec Ltd is a specialist designer and manufacturer of liquid level, position and flow sensors for use in extreme environments.
Based in the UK, we are a global leader in the design and supply of capacitive fuel level sensors for use on unmanned aerial vehicles (UAVs). Our products are used by globally-recognised integrators and manufacturers of fixed wing and VTOL UAVs.
All Reventec UAV fuel sensors use capacitive technology to detect the level of fuel within a fuel cell/tank. The sensors are solid-state with no moving parts and are designed for high-reliability in harsh, high vibration operating environments typically experienced in UAV fuel measurement applications.
Each UAV fuel sensor is manufactured to suit the intended application and installation.
A range of standard mounting arrangements are available, and sensors are manufactured to the required length. For complex or unusual installation requirements, Reventec will design a fully-bespoke product.

UAV fuel sensors custom developed for your application
The Reventec design team has vast experience designing and developing custom liquid level sensors for challenging integration requirements. We’ve designed sensors with a bend in the probe section (for L-shape fuel tanks); with a 90 degree angle in the mounting head for side-mounting; and with probe materials such as carbon-fibre for size- and weight-constrained unmanned aerial systems.
Example: Custom Fuel Sensor for Unmanned Helicopter
This custom-developed level sensor was designed to suit the existing fuel cell on a long-endurance unmanned helicopter. In order to monitor the full depth of the complex fuel cell construction, the sensor was designed with a unique bend part-way down the sensor probe-length.
