Technologies
Embedded technologies
Ultrasound
Above-ground tanks · Liquids
Emits a sound wave to measure the distance between the sensor and the product surface. Ideal for above-ground tanks containing fuels, lubricants, water or AdBlue where space is limited.
Hydrostatic Pressure
Underground tanks · Industrial liquids
Analyses the pressure exerted by the liquid column at the bottom of the tank. Ideal for underground or hard-to-access tanks — excellent accuracy for fuels, oils and industrial liquids.
Non-contact Radar
Solids · Waste · Harsh environments
Uses electromagnetic waves to measure level without touching the product. Particularly suited to solids, waste or heterogeneous materials, reliably in dust, deposits or changing conditions.
Ratiometric (Rochester / LPG)
LPG tanks · Gas sector
Reads the mechanical position of an existing Rochester, Cotrako, Rotarex SRG or Cavagna gauge. High compatibility with standard equipment in the gas sector — no tank modifications required.
Pulse (meters)
Consumption tracking · Gas, water, fluids
Counts signals emitted by a meter for each unit consumed (litres, m³, kWh). Suitable for gas, water and industrial fluid meters, enabling accurate consumption monitoring and automation.
GPS & Geolocation
Mobile tanks · Fleet tracking
Provides real-time geolocation of equipment and mobile tanks. Used for fleet tracking, logistics or rental — combines level monitoring with location data for full operational visibility.

Use Cases & Sectors
Six industries, one coherent platform.
Energy & fuels
Supply disruptions and emergency deliveries make managing energy stocks more challenging. Four Data sensors enable accurate monitoring of fuel levels. Operators can anticipate demand, optimise routes and reduce logistics costs.
Lubricants & oils
Lubricant consumption is often poorly measured and difficult to predict. Sensors provide a constant overview of available stock levels. Replenishment is automated, minimising production downtime and excess stock.
Waste & the environment
Fixed collection rounds result in unnecessary journeys and overflowing bins. Sensors measure fill levels remotely. Collections are triggered at the right time, reducing costs and environmental impact.
Gas & GPL
Monitoring gas tanks requires precision and safety. Dedicated sensors ensure reliable level readings. Operators can safeguard supply, improve planning and comply with regulatory requirements.
Rental & logistics
The management of mobile equipment often lacks visibility regarding its condition and location. Sensors that combine level and location monitoring provide comprehensive oversight. Organisations can optimise the use of their assets and improve profitability.
Agriculture / livestock farming
Agricultural silos and storage facilities are difficult to monitor remotely. Four Data sensors enable continuous monitoring of stored volumes. Farmers can plan restocking in advance and ensure business continuity.
