Why monitor tanks on an ICPE or SEVESO site ?
Understanding the challenges: safety, compliance, environment
On an ICPE or SEVESO classified site, the management of industrial tanks leaves no room for improvisation. A storage facility for chemical substances or petroleum products presents a particular risk. risk risk ofemissionof pollutionor evenexplosion. Visit treatment of these risks requires a reliable reliable measurement systemcapable of transmitting information real-time information on levels liquid levels flowsor temperature or pressure thresholds.

What is an ICPE or SEVESO site?
An ICPE (Installation Classée pour la Protection de l’Environnement) refers to any industrial industrial activity likely to emit hazardous substances or generate an impact on the impact on the environment. These installations are subject to strict regulations because of the risks related to their operation: fire, explosion, chemical chemical productswater or air pollution.
Visit SEVESO sitesThese are ICPEs subject to stricter obligations, due to the volume or nature of the substances stored (classified as H224, H225, etc.). They must implement technical provisionstechnical emergency plans and rigorous monitoring of tank levels.


Risks associated with poor reservoir management
No reliable measuring systemindustrial tanks and vessels present a number of hazards:
🔥 Fire or explosion In the event of overfilling or accumulation of flammable gases, particularly on products classified as H224 / H225.
🌍 Soil and water pollution undetected leakage or spillage of effluents or toxic substances
💨 Hazardous substance leak: uncontrolled emissions impacting operators and the immediate environment
Key figures
According to Ineris, nearly 60% of incidents reported at SEVESO sites since 2020 are linked to failure to monitor or maintain of storage equipment.
Regulatory requirements (ICPE / SEVESO decrees)
Operators of ICPE and SEVESO sites must comply with a series oftechnicaladministrative and environmental requirements:
- Installation of an automated measurement system and real-time level monitoring
- Data recording (stocks, thresholds, volumes) for control by authorities
- Detection of anomalies (leakage, overpressure, critical level) with immediate transmission
- Prevention plans for hazardous products, particularly highly flammable liquids
- Monitoring of indicators relating to 6 RV Risks: fire, explosion, pollution, substances, environment, human

Our connected telemetry solution

Real-time monitoring and data visualization
Our telemetry system enables continuous continuous measurement of your tanks, cisterns and reservoirs, regardless of the type of type of substance stored (flammable liquid, effluent, chemical product). The data is automatically transmitted to our cloud platform, which can be consulted via web interface and mobile application or on a local display.
In just a few clicks, operators can visualize the status of each installationwith values updated every X minutes (depending on the package chosen, between 2 and 5 minutes). A precise digital twin map of the site allows you to visually locate the equipment under surveillance, as well as any ancillary equipment (fire extinguishers, trucks, etc.).
Smart alerts, thresholds and incidents
Our sensors automatically trigger intelligent alerts as soon as a critical threshold is reached: level too low or too high, abnormal variation, suspected leak or overpressure.
These alerts are contextualized and can be transmitted via email, SMS or push notificationaccording to your preferences. Thanks to our rules engine, you can configure customized scenarios by tank type, stored product or risk zone.
Intelligent features :
- Detection of threshold exceedance
- Immediate notification to safety manager
- 12-month alert history
- Coupling with local automation(pump stop, valve closure)
History and full traceability
All the measurements are archived securely to ensure traceability of your tank levels over time. You can view historical values by product, plant or period (day, month, year).
Our platform also allows you toexport data in PDF or Excel format, to meet regulatory requirements or document ICPE/SEVESO inspection reports.
Sensors and connectivity (NB-IoT, LTE-M, Radar, etc.)
