FDA, HACCP, IFS, EHEDG, and EC 1935/2004: Understanding Food Industry Standards and Regulations
In the food industry, compliance with safety and hygiene standards is essential for ensuring the conformity of facilities and the quality of finished products. But between European and American regulations, design standards, and food safety certifications, it can sometimes be difficult to navigate. FDA, HACCP, IFS, EHEDG, EC 1935/2004…
What are their specific characteristics? What are they used for? Syvrac, a specialist in the storage and transfer of food powders, helps you better understand these standards and select equipment compliant with your market requirements.
The main method: the use of load cells
The most effective method for weighing a silo is to install load cells (also known as load cells) directly under the silo. These sensors measure the total weight of the silo and its contents, offering high accuracy.
Advantages
- High accuracy: The sensors provide an exact measurement of the weight of the stored material.
- Real-time monitoring: Continuous monitoring of the fill level is possible.
- Easy integration: Data can be integrated into management systems for automated monitoring.
- Avoid rigid connections: Ensure that no rigid connections (such as pipes or fixed structures) impede the movement of the silo, which could distort the measurements.
- Correct installation of load cells: Sensors must be installed in accordance with the manufacturer’s recommendations to ensure accurate measurements.
- Perform accurate calibration: Calibrating a load cell is not as easy as calibrating a hopper. For this, you can follow the Syvrac blog on load cell calibration.

How to weigh a silo?
Accurate silo weighing is essential for optimal management of powder and bulk material stocks. Whether you use flexible, rigid or stainless steel silos, it is crucial to understand the available weighing methods, their advantages and their limitations.
Alternative methods: indirect weighing systems
In some cases, particularly during modernisation projects or when budget constraints apply, alternative methods may be considered.
Systems based on structural deformation
These systems measure the deformation of the silo legs to estimate the weight of the contents. However, they generally offer less accuracy and are more suited to indicating trends than providing exact measurements. Furthermore, they do not comply with legal weighing standards, such as IFS controls.
Level measurement using sensors
Level sensors such as radars can be used to estimate the volume of material in the silo. However, this method does not take into account the variable density of materials, which can lead to inaccuracies.
Conclusion
For accurate and compliant weighing, installing load cells under the silo remains the most recommended method. Although alternatives exist, they do not provide the same level of accuracy and may not meet legal requirements.
