Without built-in calibrated scales for good reason

Our Fillogy® systems have been specially developed for filling liquids and viscous products. They work on the basis of volume and enable precise dosing. Occasionally the question arises as to whether it would not be better to install a calibrated scale directly in the machine. The answer is no – and for good reason.

According to the German Measurement and Verification Act (MessEG) and the German Measurement and Verification Ordinance (MessEV), the following rules apply to the commercial sale of products by weight:

1. use of calibrated scales

• Commercial sellers must use calibrated and verifiable scales.
• The scales must be approved by an authorized testing laboratory.

2. compliance with the filling quantity

• The specified quantity on the label (e.g. “500 g”) must be reliably achieved.
• Deviations are only permitted within legally defined tolerances.

3. regular inspection

• The weight of the filled products must be checked regularly.
• The calibration validity must be maintained by recalibration (usually every two years).

4. exception for occasional private levies

• Anyone who only sells products occasionally and without the intention of making a profit is exempt from the calibration obligation.
• As soon as the sale takes place regularly or commercially (e.g. at markets or in retail), the legal requirements apply.

A built-in calibrated scale is technically and organizationally problematic:

• Calibration is location-dependent: Temperature, installation location and orientation must be constant – difficult to implement with mobile filling machines.
• Changes may invalidate the calibration: Cleaning, product changes or conversions.
• High inspection costs: Regular on-site inspections by the Weights and Measures Office or certified bodies are expensive and time-consuming.
• Less flexibility: Different container sizes or small batches are difficult to fill.

Even with transportable machines, mobile calibration is practically impossible, as the calibration covers the entire system including the environment.

Our filling machines work precisely; for legally compliant weight control, we recommend filling with the Fillogy® machine and checking the result regularly with a calibrated scale.

Advantages:

• Legally compliant: Meets legal requirements.
• Flexible: Different container sizes and batches can be handled with ease.
• Cost-efficient: No expensive recalibrations of the filling machine required.
• Simple integration: Can be easily integrated into existing processes.

• Verifiability: Marking with “M” or corresponding certificate of conformity.
• Regular recalibration: Typically every two years, depending on the type of scale.
• Stable installation: level, level surface, free from vibrations.

• The scales are tested by a recognized testing laboratory under specified conditions.
• It receives a calibration mark and is sealed.
• The calibration is generally valid for two years, after which it must be recalibrated.
• Improper use or damage can invalidate the calibration validity.

Fillogy® filling machines are deliberately designed without a built-in calibrated scale, as integration would be technically and economically impractical. The combination of precise, volume-based filling and the use of an external calibrated scale ensures legally compliant, flexible and cost-efficient filling. This allows you to concentrate fully on filling and selling your products.
