The inline analyzer that reads the whole liquid
Installed in the process line, the Collo Analyzer reads the complete fingerprint of the liquid in real time. Your plant runs CIP and changeovers on what is actually in the pipe, not on a timer.
One analyzer, the complete fingerprint
Conventional inline sensors each measure one property: conductivity, Brix or turbidity. The Collo Analyzer contains Collo's patented RF sensor, which reads the complete fingerprint of the liquid and sees what single-parameter sensors miss.
- Product and water interfaces: the exact moment product gives way to water at a changeover, and the moment a rinse is clean.
- Dilution and composition changes: including the silent dilution that flow meters and mass balance report as a balanced plant. At one European dairy plant, flow meter errors were masking 1.3 to 2.28% dilution of the product.
- Transparent, opaque or viscous liquids: from raw milk and cream to juice and concentrated cleaning chemicals.
The RF sensor measures Collo Permittivity and Collo Ion Viscosity, and the analyzer combines them into HydroGap: a single value for how far the liquid is from pure water, which sits at zero. It holds its reference without drift, so control limits stay where you set them.
The innovation behind four awards in a year
DLG has awarded Collo a Gold Medal in the International FoodTec Award 2027, and at Alimentaria FoodTech 2026 Collo won the FoodTech Innova Award in the Sustainability and Circular Economy category. They follow the World Dairy Innovation Award 2026 at the and the World Beverage Innovation Award 2025.
All four recognise the same technology: the Collo Analyzer's patented RF measurement, which captures the complete liquid fingerprint and makes invisible losses visible and measurable.
Where it goes to work
The Collo Analyzer is the measuring device of the Collo Platform. Collo Insights turns its data into findings per line, and Collo Signals sends it into your automation. The same analyzer serves every application:
- Changeover (pushout) optimisation: the product/water interface is measured, so pushouts can end on the product, not on a timer. At Valio's Joensuu dairy, pushouts adjusted on Collo's interface analysis cut pushout losses by 92% on one cream line.
- CIP optimisation: pre-rinse, caustic circulation and final rinse end when the line is clean. A European beverage producer shortened CIP time by 23% on one line. At a global soft drinks bottler, a six-week trial identified 17% less CIP water, or 4 million litres a year at scale.
- Silent dilution detection: at raw milk reception and in cream, where water enters product unseen.
- Mixing and concentration monitoring: following a product's state in real time with a concentration model.
Every dairy liquid, opaque or clear
Raw milk, cream, cheese milk, whey and cultured products. Valio's Joensuu dairy cut pushout losses by 92% on one cream line with Collo.
Carbonated, foaming or opaque
Soft drinks, syrups, juice, plant-based drinks and beer. A global soft drinks bottler found around 4 million litres of water a year in its CIP with Collo.
Versus conductivity and turbidity
Conductivity sees ions only, drifts and needs regular recalibration. Turbidity needs light, so it cannot see through milk or cream. The Collo Analyzer reads the whole liquid, so the interface and the end of a rinse are found on the product itself.
Versus refractometers and density meters
Refractometers and density meters each reduce the liquid to one value, such as Brix or density. Refractometers also react less to ionic CIP chemicals and are costly to deploy at scale. The Collo Analyzer reads a multi-parameter fingerprint and holds its reference without drift.
Versus NIR and FTIR
NIR and FTIR give detailed chemistry, mostly in the lab with results hours later, and at a higher price. The Collo Analyzer has a lower CAPEX than NIR/FTIR and measures in real time on the hygienic process line.
Deployed in weeks, not quarters
A Collo Analyzer goes in during a planned maintenance window, and a deployment takes two to three weeks.
- Flexible installation: the analyzer fits inline with a standard hygienic connection, in several possible positions. We review the best location on your line together.
- Start where the value is: high-flow points such as transfer lines, or valuable product such as cream, ideally both.
- Low maintenance: no moving parts and no drift. Collo monitors the analyzers remotely, solves issues online and runs the software updates.
- Same hardware, every line: Insights and Signals run on the same analyzers, so a plant can switch on real-time control area by area as the findings come in.
- Protected technology: three granted patents on the RF measurement.
