Tanks, silos, and industrial containers are used across a wide range of industries, including food processing, chemicals, pharmaceuticals, agriculture, logistics, and manufacturing. In all these environments, having reliable information about fill level, temperature, and operating conditions can make the difference between efficient operations and unexpected disruptions.
Manual inspections or occasional readings provide only a snapshot of the current situation. An IoT monitoring systemcontinuously collects data, builds a historical record, and generates alerts whenever abnormal conditions are detected.
The choice of sensors depends on the type of material being stored. For liquids, pressure sensors, ultrasonic sensors, radar sensors, or load cells can be used. For powders, granules, and bulk materials, factors such as uneven accumulation, airborne dust, foam, or internal bridging must be considered, as they can reduce the reliability of standard sensing technologies.
Temperature can also be monitored at one or multiple locations. In food silos, localized temperature variations may indicate fermentation processes, increasing moisture levels, or conditions favorable to mold growth and pest infestations. In chemical tanks, temperature directly affects viscosity, product stability, and operational safety.
An IoT device can combine measurements of level, temperature, pressure, humidity, weight, and the status of valves or pumps. The collected data can be processed locally to detect rapid changes, incomplete filling cycles, abnormal consumption, discharge blockages, or potential overflow conditions.
The choice of connectivity depends on the installation site. Wi-Fi and Ethernet are suitable for facilities with existing network infrastructure, while LoRaWAN, NB-IoT, or cellular connectivity are ideal for remote, agricultural, or geographically distributed installations. Where power is unavailable, the system can operate on battery power or with a small solar panel.
A dashboard should provide much more than a simple numerical reading. It can display consumption trends, estimate remaining capacity or operating autonomy, and compare multiple tanks or facilities. Alerts can be configured not only for fixed thresholds but also for unexpected behavior, such as a sudden drop in level, a gradual increase in temperature, or a pump operating without a corresponding change in stored volume.
These insights help optimize supply planning, reduce manual inspections, prevent process interruptions, and identify leaks or equipment malfunctions. In more advanced systems, data can be integrated with ERP, MES, and maintenance management software through APIs and industrial communication protocols.
Every tank or container has unique characteristics, including its shape, material, dimensions, stored product, and environmental conditions. For this reason, an effective solution must start with a careful analysis of the specific application, rather than simply applying a standard sensor.
TechCrafters develops custom IoT systems for monitoring tanks, silos, and industrial containers by integrating sensors, electronics, firmware, connectivity, and data management. A project can begin with a prototype on a single installation, validating measurement accuracy, battery life, and data quality before scaling the solution to multiple sites or dedicated production.
