Liquid fill height vision for underfill and overfill bottle inspection on pharmaceutical, beverage, and FMCG lines. An adjacent Optomech packaging-vision capability — often combined with bottle and cap inspection — engineered in Hyderabad for Indian production speeds.
Fill level inspection — also called liquid fill height vision or underfill/overfill bottle inspection — verifies that every container leaves the filler with the correct volume of product visible as a fill line.
On high-speed liquid packaging lines in India, underfilled bottles create compliance and customer-trust risk, while overfilled bottles waste product and can cause sealing or shipping issues. Manual sampling cannot catch every short fill at production speed.
Optomech is a packaging vision OEM known for BIS, CIS, LIS, ISIVS, FOSIS, CANIS, and PBIS. Fill-level inspection is an adjacent capability — engineered for your bottle, liquid opacity, and line layout — and is frequently specified together with bottle or cap inspection on the same liquid line.
Honest positioning: We do not invent model SKUs or list prices for fill-level stations. Each installation is application-engineered — camera angle, backlight or diffuse lighting, and tolerance windows are set for your SKUs during commissioning.
The Optomech fill level station mounts on the conveyor after the filler. Exact camera and lighting geometry depend on whether bottles are clear, amber, or opaque, and whether inspection runs before or after capping.

Defectives ejected
Rejected containers are ejected automatically — the line continues at production speed.
Machine vision measures the visible fill line (or meniscus) against the programmed acceptance band for each SKU. Combined stations can also verify cap presence and seating on the same liquid packaging line.
The station integrates onto the existing conveyor. Lighting and camera angle are selected for transparent, translucent, or challenging bottle colours so the fill line stays measurable at line speed.
Filled bottles travel under the Optomech inspection head one after another at production speed — triggered by the line encoder or photocell.
Industrial cameras with application-specific LED lighting (often backlight or controlled side light) capture the fill region with high contrast.
Software locates the fill line / meniscus and compares it to the SKU recipe. Result: pass, underfill, overfill, or empty — in real time.
Defective units are ejected pneumatically. Reject images and counts support QA review, filler tuning, and audit trails.
Camera count and optics selected for your bottle diameter, neck finish, and liquid colour — not a one-size gadget bolted on without validation.
Backlight, diffuse, or side illumination chosen so the meniscus remains stable under factory ambient light and across clear, amber, and frosted packs.
Named recipes store fill bands, camera settings, and reject logic per product. Changeovers recall the correct tolerance window without re-teaching from scratch.
Fill level is designed as part of Optomech’s packaging vision stack — combine empty-bottle QC, fill height, and cap inspection into one coherent line programme.
Underfilled and overfilled containers are removed without stopping the conveyor. Rejection verification can be added where the line requires confirm-eject.
Live images, fill statistics, and recent rejects help operators see filler drift early — before a whole shift of short fills ships.
Role-based access keeps fill tolerances from being changed casually. Reporting supports QA, regulatory, and customer audit needs on pharma and FMCG lines.
Optomech engineers in Hyderabad can assist with diagnostics and parameter updates remotely when site access is limited — reducing downtime.

Any liquid packaging line where short fill or overfill creates regulatory, brand, or cost exposure benefits from 100% fill height vision.
Syrups, suspensions, oral liquids, and related packs where declared volume and GMP discipline matter. Often specified with Optomech bottle and cap stations on the same line.
High-speed beverage and water lines where underfill drives consumer complaints and overfill drives giveaway. Fill height vision keeps filler performance visible shift by shift.
Shampoos, oils, household liquids, nutraceutical liquids, and agrochemical bottles — where consistent fill supports brand trust and packing efficiency.
Optomech designs and manufactures machine vision inspection equipment in Hyderabad. Fill-level stations inherit the same engineering discipline as BIS, CIS, and our specialised systems.
Fill height is rarely a lone requirement. We plan fill-level vision with bottle, cap, label, and seal inspection so your liquid line has one coherent quality story.
Lighting, optics, and tolerances are validated on your bottles and liquids. We avoid shipping generic boxes with invented SKUs or brochure-only claims.
Engineers install, tune fill bands, train operators, and stay until reject rates and false rejects are understood for your SKUs.

Manufacturers across pharma, plastics, and FMCG already run Optomech vision systems. Fill-level capability extends that same partnership model.
