Weighing up to 10 tons per Silo foot
With silo and container scales, you always stay in control of inventory
Silos provide plenty of space for storing all kinds of raw materials. To keep an accurate overview of a silo's fill level at all times, it is advisable to monitor stock levels by weighing the entire silo or container. Only if the inventory of required raw materials is correct can smooth production be ensured. Silo or container scales are specifically designed for weighing such large containers. They usually consist of an easy-to-install kit that can be optimally adapted to the respective silo.
How does a silo scale work?
The silo or container scale consists of several load cells and a display unit. The number of load cells depends on the number of support legs of the silo – typically 3 or 4. One tank load cell is mounted under each leg. The individual load cells are connected via a junction box and read out through the indicator. Calibration is usually not required, as the kit is typically delivered pre-calibrated. Depending on the control or display unit used, multiple container scales can be combined, enabling the mixing of different materials.
How many support legs can a silo scale have?
BOSCHE silo scales are suitable for silos and containers with tank load cells for 3 to 10 support legs.
What is the maximum allowable total weight of a tank load cell system?
The total weight capacity of tank load cells depends on the number and type of load cells. For example, with a rated capacity of 10 tons per leg, we recommend loading the system to 2/3 of the maximum. That means for a container with three legs, the maximum load including the silo’s own weight would be 20 tons (3 × 10 tons × 2/3 = 20 tons).
What can I weigh with tank load cells?
With a silo scale equipped with tank load cells, you can weigh both solid and liquid materials. Silo scales are often used in agriculture for weighing grain and feed. Liquids can also be weighed in the same way.
Can I also use a silo scale for filling or dosing?
Yes, with the appropriate weighing electronics and tank load cells, simple control processes for filling, emptying, or dosing can be implemented. More complex tasks can be programmed using an external PLC. For this, weighing transmitters or strain gauge amplifiers with suitable digital or analog outputs are ideal.
Fields of Application for Container and Silo Scales
The possible applications for such scales are as diverse as the raw materials stored in large containers. Silo scales are typically used in industrial environments where large quantities of raw materials must be kept available. Thanks to the fact that these scales can be easily combined, entire mixing processes can be controlled through such a weighing system. Silo scales are also useful for loading vehicles, as a precisely defined amount can be extracted from the container, eliminating the need for re-weighing the loaded vehicle.

With our innovative silo weighing components, remote monitoring of your silos and tanks becomes child's play. Connected via a cloud (IoT), you can access fill levels and weights online in real time – anytime, anywhere. This allows you to optimize your processes and increase the efficiency of your operation.
Components Certified According to DIN EN 1090
Certifications are often seen as an additional burden with excessive bureaucracy and unnecessary regulations. However, they are an essential tool for quality assurance, contributing significantly to process reliability through error prevention and optimization. Since July 1, 2014, all load-bearing components made of steel or aluminum must go through the conformity verification process according to DIN EN 1090. Since silos and bulk containers fall under the Construction Products Regulation, and the corresponding weighing modules must bear the full load, this standard applies to them as well. These types of scales can be used in many areas – for example, in industry where large quantities of raw materials must be available, or for vehicle loading, where a precisely defined quantity can be extracted without reweighing the loaded vehicle. At BOSCHE Weighing Technology, we only use weighing modules that comply with DIN EN 1090.
Tank load cells from BOSCHE are suitable for both indoor and outdoor use. Our tank load cells are delivered ready-to-install as complete weighing systems for mounting on silos, tanks, and containers. The weighing module consists of a tank load cell with direct force transmission at each container foot. The tank load cells are connected to the weighing terminal via a junction box (e.g., JBB-04 terminal and trim box) for strain gauge load cells. Our tank load cells are pre-calibrated at the factory and are ready for operation immediately after installation. The weighing modules are mounted directly between the foundation and the container supports.
With strain gauge transmitters, the values from the tank load cells can be determined quickly, accurately, and reliably. Tank load cells can be connected directly to an indicator by wiring them to a junction box (see image), which can then be connected to a BOSCHE MWI indicator or a transmitter (e.g., BOSCHE transmitters WTB or WTS). Transmitters designed specifically for silo applications support all common fieldbus protocols. More information about weighing transmitters and indicators for silo scales can be found in our online shop at BOSCHE.eu
Proper Force Transmission is Key to Accurate Measurements in Tank Load Cells

Regular fill level monitoring with a silo scale helps ensure accurate inventory management and timely restocking. It also allows correct mixing ratios to be set. With tank load cells from BOSCHE for outdoor containers, you're always informed about your silo levels. The weighing system consists of a stainless steel load cell with a galvanized mounting module, combined with a weighing indicator. BOSCHE’s tank load cells as modules feature overload protection and offer long service life. They are available in weighing ranges of 3, 5, 10, and 20 tons per silo foot.
Application Example
Filling with a Silo Scale
How much is left in the silo? How do I mix the correct ratio? Am I dispensing the right amount? These questions are easily answered with the right silo scale. For example, combine a BOSCHE weighing module with the CSW weighing controller. This enables single-component dosing for filling a tank or dispensing specific quantities (in this case, the container underneath the tank is weighed). Multiple formulas can be stored and accessed at any time. All settings/values can be entered directly using the 5-key membrane keypad. The weighing transmitter is equipped with 5 outputs (max. 115V AC / 60 mA) as standard – perfect for controlling relays. Each CSW-C also includes 3 logic inputs.
Control Process of a Silo Scale
To start the filling process, the 3 logic inputs (Start, Stop, Tare) can be used. Components can be mixed, filled, or dosed. Predefined outputs (Preset, Set, Cycle End, Tolerance, Alarm) simplify setup for dosing and filling operations.
