Lightweight, precision liquid level sensors
- Continuous high accuracy level measurement
- Compact, lightweight & robust aluminium construction
- Proven reliability in demanding environments

LevelLite lightweight liquid level sensors are proven in aerial and track applications measuring high performance fuel, oil and coolant levels. LevelLite combines high accuracy measurement with low weight to allow operators to achieve maximum unmanned aerial vehicle (UAV) flying time or race winning track performance. As well as being light weight, LevelLite also offers a range of compact mounting options to accomodate restricted spaces.

LevelLite, lightweight high performance liquid level sensors for continuous high accuracy level measurement - more details
Designed & Manufactured by Gill Sensors & Controls in the UK, LevelLite liquid level sensors provide precision level measurement of high performance fuel, oil and coolant levels for applications where weight and space are at a premium.
LevelLite provides proven reliability in demanding environments and is chosen for UAV and motorsport applications including multiple world championship winning cars (Formula 1, Le Mans 24, World Endurance Championships and Word Rally). LevelLite level sensors are lightweight, solid-state capacitive level sensors available in many configurations of length and mounting arrangement. Custom manufacture is possible in as little as 2 weeks.
In addition to liquid level measurement, LevelLite sensors also provide a secondary switched or temperature output.
Every sensor is factory calibrated to customer requirements with temperature compensation to provide market leading accuracy as well as quick and easy setup.
A tank profiling feature allows LevelLite to provide accurate tank volume output results even in irregular tank shapes.
Flexible mounting options – many standard mounting adaptors are available from Gill where kits include seals and fixings. However, you may choose to design your own custom configuration for either panel gasket, male thread or female thread mounting. See the ‘How to fit LevelLite flanges’ video in FURTHER RESOURCES tab.
Output protocol options for LevelLite are industry standard with the ability to set custom ranges where required. Primary level output voltage 0.25-4.75V DC (max range 0.25-10V). Secondary output open collector 50V/1A max switch to ground (V-). See the How-to Open Collector guides in the FURTHER RESOURCES tab.
Environmental protection to IP68.
LevelLite level sensors have no moving parts and as a result are extremely reliable and accurate, requiring minimum maintenance.
To order, simply tell us your probe length requirements, cable exit preference (top or side), secondary output choice and the fuel/oil/water/coolant type for calibration and we will produce a fully sealed and ready to use sensor. You can then choose an off-the-shelf adaptor or request the CAD data to produce your own customised adaptor.
Liquid Level Sensor Accessories
Gill liquid level sensors are supported by standard accessories to assist with specific installation requirements.

Flange Kit (5 options)
A range of mounting options are available for the LevelLite, lightweight liquid level sensors, allowing secure installation. In addition to the 1, 2, 3 and 5-bolt mounting options, custom mounting configurations are available in both metric and imperial male thread designs.

USB to RS232 adaptor
The USB to RS232 cable adaptor allows connection of a Gill LevelPro or LevelLite liquid level sensor to a computer where the sensor can be quickly configured using GSlevel software. (only the FTDI USB-RS232-WE-1800-BT_5.0 is fully supported – other converters may not be compatible).

Liquid Level Display
Gill Liquid Level Display can be programmed to ‘map’ the tank shape to display true volume rather than simply liquid height.
Provides a real-time quick visual reference and an accurate numerical reading (using 29 bright LEDs and a seven segment panel) with light-sensitive auto-dimming for night use.
Fully programmable with a low level alarm.
Compact and lightweight for easy installation on dashboards and instrument panels (shallow 6mm depth aluminium bezel).
GSlevel Software

Overview
GSlevel software is designed for easy level sensor customisation and is free to download. The software allows control over output settings, minimum and maximum levels and alarm switch levels for ultimate adjustability.
GSlevel also allows the user to achieve a volumetric output using its tank profiling feature. Users can reconfigure the sensor using the simple configuration wizard or by uploading a CSV file to profile a cross-section of the data to gain a volumetric output.
Compatible products: LevelPro, LevelLite and LevelSlick.
Compatible operating systems: Windows® 7 or later
