Level sensors play a crucial role in the marine sector for monitoring tanks and containers for fuel, water, and other liquids. They ensure a safe and efficient supply on ships, submarines, and offshore platforms. Modern sensors provide precise measurements and are resistant to salty air and high-vibration environments. Reliable level sensors help optimize refueling, maintenance, and operations while minimizing environmental risks. This makes them an indispensable component of maritime safety and efficiency.

Gill Sensors & Controls is a leading manufacturer of rugged semiconductor sensors based in the United Kingdom. The company specializes in innovative measurement technologies for demanding applications in the marine, industrial, and research sectors and presents a groundbreaking solution with its two level sensors, which were developed specifically to meet the requirements of seagoing vessels. Both models use capacitive measurement technology without moving parts, floats, or mechanical connections. This means: no components prone to wear, minimal maintenance requirements throughout the ship’s entire service life, and stable readings even when the ship is moving and the liquid level in the tank fluctuates.

LevelPro Level Sensors

These sensors enable continuous measurement even in harsh environments and with aggressive media. They are made of marine-grade 316 stainless steel, feature fully sealed electronics, and operate over a wide temperature range up to 125 degrees Celsius. Fuel, oils, coolant, as well as fresh and salt water are reliably measured despite the heat and vibrations in the engine room.
LevelPro sensors operate reliably even in the harshest marine environments. In Class 1 offshore powerboat racing, seawater ballast tanks are subjected to repeated extreme shock loads at speeds of nearly 200 miles per hour. The sensors originally installed on these tanks lasted only one or two races before failing under these conditions. The capacitive Gill sensors that replaced them operated for eight years without a single failure. Gill level sensors are also installed fleet-wide in Griffon Hoverwork’s hovercraft, where they monitor fuel levels in an environment of severe vibration and turbulent sea conditions over a seven-year service life.
Each sensor is factory-calibrated and temperature-compensated, making it ready for immediate use. A tank profiling function accounts for irregular tank shapes to display the actual volume rather than just the liquid level, and thanks to a built-in high- or low-level alarm output, an independent switch is included without the cost of a separate device.
Although the sensors are not ATEX-certified, certification can be obtained for projects of sufficient scale.

LevelSlick Sensors

They were specifically developed for challenging liquids such as slurries, wastewater, colloids, and media containing suspended solids. Thanks to their design—which features no openings or moving parts—clogging or blockages are virtually impossible. The PTFE-coated surface also ensures long-lasting measurement accuracy and prevents drift and incorrect readings over time.
LevelSlick sensors feature a simulated resistive output and are available in both current and voltage versions.
This innovative sensor solution provides a reliable basis for the precise monitoring of liquid levels in a wide variety of applications, such as wastewater and blackwater tanks – designed for use even under the most challenging conditions on the high seas.
Like LevelPro, LevelSlick is factory-calibrated, features tank profiling to determine the actual volume, and is equipped with an integrated level alarm.

A Single Provider for the Ship’s Critical Tanks

Both sensor lines are designed for easy integration, minimize maintenance requirements, and are built to last. With a shared software platform, they offer a comprehensive solution for monitoring a wide variety of tank types—from fuel and oil tanks to wastewater and sewage tanks.
