This unit is designed for filling operators that must guarantee zero non‑compliant goods going to retail.
Application sectors:
• Beverages: still water, sodas, beer, carbonated products, juice, tea, cold‑brew coffee
• Dairy & plant‑based liquids: milk and alternative liquid dairy‑style goods
• Food: sauces, edible oils, condiments and other liquid foodstuffs
• Pharma & chemicals: liquid pharmaceuticals, solutions, cleaning fluids
Container range: 60 ml to 1 000 ml; larger capacities are custom‑available. Works with aluminium cans, tin cans, PET, PE and glass bottles.
Scan: Filled containers travel via single‑lane conveyor through the X‑ray inspection tunnel.
Assessment: Fill‑level values are measured and cross‑checked against your configured minimum fill‑level limit.
Position tracking: An encoder fitted to the conveyor synchronous motor tags every faulty unit with a unique ID. Accuracy is maintained during line speed shifts and line stops.
Rejection: Defective packages are pushed out through a maximum‑15‑cm opening in the safety guard, accompanied by audible plus visual warning signals.
Collection: Rejected units fall into a heavy‑duty collection bin installed at the reject station.
Rejection logic is based on tracked individual container IDs instead of timer‑based timing. This eliminates false rejects when production lines speed‑up, slow‑down or halt.
As published in the Cassman engineering proposal (June 2026). Final configuration is tailored to your container and line.

Where it goes: after the filling machine, and either before or after the coder.
Line requirement: mounts on a single-lane conveyor with a straight section of at least 2 meters.
Conveyor modification: cut a guardrail gap of ≤15 cm at the straight section to act as the reject exit.
Composition: detection unit, rejection unit, power distribution cabinet, HMI, electronic and mechanical components.
Installation time: completed within 24 hours on site.
Send us your conveyor height, line speed, and container drawings and we will confirm fit before production.
Key components are imported for performance and reliability:
X-ray emitter — Japan
X-ray receiver — Japan
HMI — Taiwan
On inspection results, the system is built to perform comparably to leading international brands such as Heuft (Germany) and Krones (Germany), at a price point suited to growing fillers.
Certifications: CE, SGS, ISO 9001 quality management, TÜV, and CSA, plus an Alibaba Verified Supplier credential. Manufactured by Jinan Cassman Machinery Co., Ltd. — 15 years of experience, a 15,000 m² factory, and an installed base across 65 countries.
Is X-ray fill level inspection safe? Does it make the product radioactive?
Yes, it is safe. The machine uses a low-energy X-ray tube — not a radioactive isotope source — and emission stops automatically when no container is present. There is no residual radioactivity in the product, consistent with how non-isotope X-ray fill inspectors are described across the industry, including Thermo Scientific InScan.
Can it inspect aluminum cans and opaque bottles?
Yes. That is the main reason to choose X-ray over optical sensing — it reads the liquid level through metal cans, dark PET, labels, and printed sleeves that block optical and many high-frequency sensors.
What is the highest speed it can run?
Up to 36,000 bottles per hour, at a conveyor line speed of ≤1.6 m/s. The exact rate depends on container size and diameter.
How accurate is it?
±1 mm static and ±1.5 mm dynamic resolution, with a ≥99.9% reject rate for non-conforming containers. Foam and sloshing can affect accuracy, so we tune the configuration to your product.
What does it detect?
Low liquid level (underfill). Out-of-spec containers are rejected automatically with audible and visual alarms.
How long does installation take?
On-site installation is completed within 24 hours, provided the line meets the single-lane, 2-meter straight-section requirement.
