Real-time volume measurement in Polish mineral plantsReal-time volume measurement in Polish mineral plantsReal-time volume measurement in Polish mineral plants

The Polish bulk-handling industry has moved fast over the last 18 months. When Powder & Bulk Poland covered our growing footprint there in February 2026, the article counted active OWL EYE® installations across cement, aggregates and recycling sites — and the trajectory points up.

Three drivers explain the wave.

1. ESG reporting now needs real numbers. EU CSRD reporting obligations reached a tier of mid-sized Polish industrial operators in 2024 and 2025. Material balances reported at the corporate level need to reconcile to measured inventory, not to ERP bookings. A continuous LiDAR measurement closes that loop without adding headcount in the controlling department.

2. Labour costs in surveying climbed faster than capex. A weekly manual inventory by total station was a viable cost model in 2018. By 2025 the fully-loaded hourly rate of a qualified mining surveyor in Silesia had caught up with the German ranges. The math on a fixed OWL EYE® STOCKPILE installation now works at sites that would not have considered it five years ago.

3. Retrofit friendliness. This is the operational point — and the one the Powder & Bulk Poland article emphasises. Polish cement and lime plants often run on infrastructure that has been extended in three or four generations. A new measurement system that requires civil works at every pile is a non-starter. The OWL EYE® mounting catalogue ships with brackets that fit standard industrial profiles (Bosch / Item 30 mm), existing crane gantries, ad-hoc roof penetrations — anything that has a power feed and a data path within reach. A typical installation takes one to two weeks per pile, no concrete pour, no shutdown longer than the cable pull.

Local-language dashboard. Smaller but practical: the operator-facing dashboard runs in Polish, German or English depending on the user account, with the same data pipeline behind it. Shift supervisors do not have to translate technical terms in their head, and that visibly speeds up the adoption curve in the first weeks after commissioning.

What the typical Polish rollout looks like. Across the cement and aggregate operators we have onboarded since early 2024, the rollout pattern is consistent:

• Phase 1. One pile, one sensor cluster, one ERP integration. Three to four months from contract to live data. Used as the internal proof point.
• Phase 2. Two to four further piles plus the main feed bunker (using the BUNKERS & FEEDERS variant). Six to nine months out from Phase 1.
• Phase 3. Belt-flow integration on the main outloading conveyor (VOLUME FLOW) and, on truck-heavy sites, the drive-through scanner (TRUCK TERMINAL). Twelve months and beyond.

Not every site reaches Phase 3, and that is fine. The architecture is modular for a reason — the system that scans pile 1 in month 3 will keep running unchanged when pile 6 comes online in month 18.

Specs that matter on Polish sites. The technical envelope is the same as everywhere else: LiDAR range 5–200 m, IP65+ enclosure, operating temperature −40 °C to +80 °C, ±1 % volumetric accuracy after on-site calibration. Polish winters in the north regularly hit −25 °C; the heated optics handle that without intervention.

Where it goes from here. The next twelve months will see further expansion in cement, the first installations in the Polish copper sector (where Aurubis already runs OWL EYE® in Hamburg), and a growing service business around the annual reference inventories that complement the fixed installations.
