Why monitor the water level in a tank?
Water stored in a tank or reservoir is a strategic resource. Whether for domestic, agricultural or industrial use, rigorous liquid level management is essential for optimize consumption, avoid incidents and maintain service quality.
Knowing the quantity of water available at all times enables you toanticipate needs, d’organize refills or deliveries or deliveries, andavoid wastage related to overfilling or undetected evaporation. This approach is in line with the objective of cost control, security of supply and respect for the environment.
By making level measurement more precise, more frequent and, above all, more remotely accessible, an intelligent sensor becomes a lever for performance and peace of mindwhatever the application.
Risks associated with incorrect level monitoring
Failure to keep a close eye on the water or liquid level in a tank can have serious consequences:
- Overflow or underfilling A poorly monitored tank can overflow during heavy rainfall, or run dry at the height of demand, creating flooding or service interruption problems.
- Interruption of use For a private individual, this could mean cutting off watering or the domestic water supply; for a farmer, it could mean disrupting irrigation or livestock watering; for an industry, it could mean stopping a critical process.
- Loss of control over consumption: without reliable measurement, it is impossible to detect leaks, monitor stock levels or optimize usage. This can lead to cost overruns and undermine overall efficiency.


Who needs this solution?
A wide variety of players can benefit from a connected control system. connected system:
- Individuals for monitoring the level of a rainwater harvesting system, well or borehole, and thus maximize water autonomy while avoiding wastage.
- Farmers When it comes to irrigation, livestock farming or the storage of technical liquids (fertilizers, fuel), accurate monitoring of tank levels is crucial to planning operations and avoiding supply shortages. to plan operations and avoid supply shortages.
- Industry and local authorities: whether for process vessels, sanitary water tanks or chemical products, reliable, continuous information is essential to guarantee safety, compliance and continuity of service.
A connected sensor for intelligent water management
Avoid tedious manual checks, gauge errors or surprises at the critical moment. Thanks to our connected sensormonitoring the water level in your tank becomes automatic and remotely accessible.
Designed for easy to install, robust to outdoor environments, and compatible with a wide variety of liquidsthis product combines advanced measurement technology, IoT connectivity connectivity and intuitive user interface. It’s a all-in-one solution that turns any tank into an intelligent control system.

The benefits of a connected water level sensor
The adoption of a connected sensor does more than simply display the level: it transforms tank management into a lever for efficiency, savings and peace of mind.efficiency, savings and peace of mind. Here are the most tangible benefits.

Controlling consumption and costs
- Visualize in real time the exact level of your tanks, expressed to the nearest millimeter accuracyfrom your phone or computer.
- Track measurement history to analyze consumption variations over time.
- Anticipate fill-ups with intelligent forecast curves that take into account your usage habits.
- Reduce losses by identifying periods of over-consumption or filling anomalies.
- Optimize usage according to available stocks and priorities (watering, production, domestic use, etc.).
Smart alerts
- Receive notifications in the event of a problem : low threshold reached, imminent overflow, leak detection or unusual behavior.
- Choose your preferred channel email, SMS or mobile application.
- Configure your critical thresholds according to the characteristics of your tank, your liquid or your usage.
- React quickly before an incident impacts your operations or equipment.
Time-saving peace of mind
- Monitor your installations remotelywithout having to visit your site, even from several kilometers away.
- Avoid manual checks tedious, inaccurate or dangerous.
- Get a clear, concise overview level data, whatever your level of technical expertise.
- Centralize multi-tank management from a single interface if you manage several sites or tanks.
Easy installation and compatibility
One of the most frequent obstacles to the adoption of connected solutions remains the fear of a complex installation or incompatibility with the existing tank.
