In coolant management, there are three paths to automation: partial, full, or hybrid automation. All have their justification, but in the end, economic efficiency is what matters.

For small and medium-sized enterprises in particular, we at GIMAT have defined a smart middle ground with the DOSIMETRIX (registered as a utility model with the German Patent and Trademark Office, DPMA): hybrid automation.

What does it entail?

1. Automatic core: Mixing and dosing are 100% automatic (eMix1500). This guarantees maximum precision and stabilizes the process on a long-term basis.
2. Real-time transparency: The fill level is continuously monitored “live” and without contact. The system operates completely maintenance-free in this regard.
3. Human-in-the-loop: The human operator remains the crucial corrective element. Why? Because any inline sensor technology—no matter how precise—requires regular attention when dealing with demanding media (such as esters or glycol) or the “natural” pH drift. We do not promise a “one-size-fits-all, all-inclusive carefree package” that ignores physical necessities. Targeted digital manual measurement is often more reliable here than highly complex sensor technology that still requires manual cleaning and calibration.
4. Closed-loop digitalization: All data flows into the FLUIDAS cloud. The system automatically reports requirements, controls the replenishment process itself, and documents everything in a legally compliant manner. This creates a closed control and information loop (see graphic).One detail that makes our ‘closed loop’ particularly efficient: If you use ATAGO refractometers, you can transfer the measured values directly to the app and the FLUIDAS cloud using the integrated NFC function. No manual logging, no transmission errors. For all other measured variables, the system remains flexible and allows manual entry—ensuring the data foundation for the eMix1500 is always complete.

Conclusion:

If an expert has to be on-site anyway for the maintenance of the measuring systems, our hybrid approach is often the smarter path: It massively relieves personnel of mixing and dosing tasks, while leveraging human expertise for the final checks.

This saves high investment costs and creates genuine transparency—without raising false expectations of maintenance-free full automation.

How do you handle this in practice? Do you consistently rely on “full auto,” or is the human factor still the most important supervisory authority in your operations?

Here’s how it works:

1. Manual measurements of oil concentration using ATAGO digital refractometers.
2. Manual entry of the respective oil concentrations into the eMix1500 from Brisco Systems GmbH, one of the most advanced automatic mixing and dosing systems for cooling lubricant emulsions.
3. Contactless level sensors from GIMAT Liquid Monitoring.

This keeps the levels in the individual tanks at the machine tools (almost) constant. And the concentration is always at the optimal level.

As an authorized distributor for ATAGO (Japan) and Brisco (Switzerland), you get everything from GIMAT as a single source!

Rain can significantly disrupt the activated sludge process in a treatment plant. Case studies show that even 10 mm of precipitation can temporarily impact the BOD value in the influent—with effects measurable at the effluent for over 24 hours. This demonstrates how critical even seemingly minor changes in the inflow can be.

Overview of Process Engineering Impacts:

• Dilution: Rainwater reduces the concentration of organic substances needed by microorganisms in the activated sludge process.
• Sludge Washout: Activated sludge can be washed out of the biological treatment stage.
• Reduced Contact Time: A decreased hydraulic retention time limits the period available for the degradation of organic matter.
• Nutrient Deficiency: Diluted wastewater leads to fewer available nutrients, which restricts microbial activity.

This is where the advantages of SENTRY probes come into play: With SENTRY sensors, such effects can be detected in real time. You receive timely data that enables optimal control of your plant—even under rapidly changing influent conditions.
