X-Ray Fill-Level Inspection Systems UK

Inline X-ray fill-level inspection for cans, coloured glass, cartons and opaque containers, with overfill, underfill, missing-product and reject control.

Application-led inspection

See the fill that an ordinary camera cannot.

Metal, coloured glass, printed sleeves and opaque plastic hide the product boundary. X-ray inspection measures attenuation through the pack to identify the fill region or missing contents without opening or contacting the container.

Typical checks

✓Underfill and overfill in opaque packs
✓Missing or grossly incomplete product
✓Fill height in cans and coloured containers
✓Product presence through closed packaging
✓Tracked automatic rejection
✓Inspection events and production statistics

How it works

Non-contact inspection through the container

Product density, pack material, wall thickness and geometry influence the result. We assess real samples and line conditions to establish whether X-ray is the appropriate technology and define the required guarding, conveyor and reject arrangement.

01

Opaque containers

Inspect cans, cartons and plastics where the contents are not externally visible.

02

Complex decoration

Avoid relying on a clear optical path through heavy print, labels or sleeves.

03

Complete cell

Integrate inspection, guarding, controls, tracking, rejection and confirmation as one scope.

Suitable applications

Built around the product and the production line.

Final suitability and performance are confirmed against representative samples, pack formats and real line conditions.

Metal food and beverage cans Opaque plastic bottles and jars Coloured glass containers Cartons and composite packs Closed pharmaceutical packs Household and chemical products

Buyer specification

Prove contrast through the complete pack.

X-ray can inspect contents hidden by metal, coloured glass, printed sleeves and opaque plastic. The usable signal still depends on the product density, pack geometry, wall thickness and required defect size.

01

Feasibility

Use representative good and bad samples to confirm that the required fill or missing product produces measurable contrast.

02

Integration

Engineer the conveyor, guarding, access, controls and reject arrangement around the selected inspection geometry.

03

Operation

Provide recipes, test procedures, fault monitoring, event records and training appropriate to the application.

Practical answers

Questions production teams ask.

Final performance is application-specific and is confirmed using representative packs, products and line conditions.

Ask an engineer
Why use X-ray for fill-level inspection?

X-ray can reveal product through packs that block visible light, including cans, coloured glass, cartons and opaque plastics. It is considered when a camera cannot obtain a reliable view.

Can X-ray inspect both fill level and contaminants?

Some system configurations can perform additional product-integrity or contaminant checks, but capability depends on the product, packaging and inspection geometry. The required defects must be proven with samples.

Can X-ray be retrofitted to a line?

Often yes, subject to conveyor access, guarding, pack spacing, available footprint, reject distance and the operational risk assessment.
