MetriX­Freight L335 measures black foil

When black becomes transparent

All new MetriX­Freight L335 solution for precise freight measurement

Erlangen, September 10, 2025 – Black stretch foil has long been one of the major challenges in automated freight dimensioning because it is glossy, reflective, and difficult to capture. With the new MetriX­Freight L335, metrilus has developed a solution. Within 200 milliseconds, the system precisely and automatically measures pallets wrapped in black foil. The result is a reliable, legal-for-trade data basis, less effort, and greater efficiency across the entire logistics process.

Black stretch foil is indispensable in logistics. It conceals valuable goods, protects from prying eyes, and helps prevent theft. But what is an advantage for security has until now been a real problem for camera-based dimensioning systems. The foil shines and, depending on the viewing angle, either shows mirror-like reflections or appears like a black hole that almost completely absorbs the incoming light. As a result, contours and edges blur. Exact measurement was hardly possible. For this reason, reliable and precise measurement in combination with black foil has long been considered difficult to impossible. Yet reliable dimensions are the foundation for every decision in logistics. metrilus has developed a solution that works reliably not only in tests but also in daily operation.

Precise dimensions are essential

Without reliable data on the length, width, height, weight, and volume of a shipment, the entire fulfillment process slows down. Accurate data is the backbone of logistics. It drives planning, transport, invoicing, and space utilization. Unclear or incorrect dimensions lead to delays, recalculations, and unnecessary costs. Those who capture data correctly and automatically save time, avoid errors, and create transparency. However, black foil wrapping has so far made automated capture difficult. Traditional approaches with markers, QR codes, or reflective dots were cumbersome and saw little demand in practice.

L335 is the solution

The metrilus development team faced this challenge and solved it. With the new MetriX­Freight L335, precise, camera-based measurement is now possible even with black foil. This was made possible by years of development, targeted and sometimes extensive training of machine-learning models, and the optimization of numerous process steps.

Within just 200 milliseconds, the MetriX­Freight L335 system reliably measures any pallet wrapped in black foil – completely without additional markers and without compromises.

Moreover, the MetriX­Freight L335 is OIML/MID certified and therefore legal-for-trade. This certification is crucial when measurement results must be legally binding, for example for freight-rate billing or documentation to customers and partners. A certified system ensures that measured data is not only technically correct but also legally valid. That creates transparency, trust among business partners, and a solid foundation for confident decisions.

“We are proud of our development team, which has created a real milestone with the MetriX­Freight L335. This lets us make an essential part of logistics not only smarter, but also more reliable and efficient,” says Dr.-Ing. Christian Schaller, CEO of metrilus.

Clear benefits for operations

With the new system, logistics companies benefit on multiple levels. Precise dimensions ensure correct freight rates and prevent costly re-invoicing. At the same time, warehouse space and truck loading space can be utilized better because every volume is captured reliably. Automated measurement saves time in daily operations, reduces sources of error, and creates more transparency. Because the MetriX­Freight L335 integrates seamlessly into existing IT landscapes, the captured data is immediately available for operational processes and strategic analysis. Thanks to the OIML/MID certification, the results are legally compliant and can be used for official invoicing; a decisive competitive advantage.

“For us, the L335 is an important step, but not an end point. We continuously work to make our systems even smarter and to provide our customers with solutions that simplify processes and truly support day-to-day operations. In doing so, we follow our guiding principle taking logistics to new dimensions,” adds Dr.-Ing. Christian Schaller.
