Accuracy in action with FireDos

FireDos Technical Team examines how new smart proportioners merge proven mechanical design with digital intelligence and enhance system readiness for critical facility protection 

For decades, testing foam extinguishing systems meant taking a hands-on approach – physically measuring foam solution samples, calculating proportioning rates and recording results in a maintenance log.

While effective, these manual methods have always carried a certain risk of human error, whether in reading, calculation, or documentation.

In fire protection, where accuracy determines performance, even small mistakes can have costly or dangerous consequences.

FireDos has introduced their new generation of proportioners with an optional monitoring system – combining the proven reliability of mechanical design with the intelligence of digital technology. The result is a smarter, safer and more efficient way to ensure foam systems are always ready to perform. 

From manual checks to digital assurance 

Traditional proportioner checks involve generating a foam-water premix and measuring its properties or calculating proportioning rates from water and foam agent flow volumes. Even with improved methods – such as operating in a “return/test mode” that recirculates the foam agent back to its tank to avoid waste – the process still relies on operator precision. 

Smart proportioners take this process into the digital age. Built on the same mechanical principles that have powered thousands of FireDos systems worldwide, they add a suite of sensors, a control unit and optional displays to handle measurement, recording and calculation automatically.

The proportioning rate – the single most important parameter in foam system performance – is calculated in accordance with recognized international standards, eliminating potential math or transcription errors. 

How the smart system works 

In test mode, the foam agent is circulated through a return line instead of being mixed into the water stream. Flow meters measure both the foam agent and water volumes simultaneously and the monitoring system calculates the proportioning rate instantly. All data is stored in a log file, complete with time stamps, ready for review. 

For facilities that need full operational tracking, an optional flow meter in the proportioning line enables measurement during actual firefighting or live drills.

This means operators can verify not only that the system works in theory, but that it delivers precise results in real-world conditions. 

The monitoring system’s wireless interface connects to smartphones, tablets, or laptops, allowing easy visualization of parameters on-site or remotely. Where required, data can also be displayed locally on an integrated screen. 

Advantages for operators and owners 

Smart proportioners offer a range of benefits that go beyond accuracy: 

  • Flawless proportioning rate determination – No manual calculations, no transcription errors; results are precise and standards-compliant every time. 
  • Maintenance reminders – The system tracks dates and can notify operators when the next service is due, ensuring inspections are never missed. 
  • Continuous measurement – Unlike periodic checks, smart proportioners can measure the proportioning rate continuously across the system’s entire flow range. 
  • Usage documentation – In the event of a fire, the system can record total water and foam agent consumption, providing valuable data for insurance claims, regulatory reporting, or environmental documentation. 
  • Expanded parameter monitoring – Additional sensors can track foam agent temperature, pump oil level, valve positions and total operating hours. 
  • Remote diagnostics – Even without direct system access, technicians can review display images or live video calls to troubleshoot issues before traveling to the site, reducing both downtime and costs. 

Saving time, money and resources 

The ability to perform remote diagnostics and reduce on-site visits is more than just convenient – it’s cost-effective. Travel expenses for specialized service technicians can be significant, especially for remote or offshore facilities. By addressing many issues before they require a site visit, smart proportioners cut both service costs and downtime. 

Environmental considerations also play a role. The return/test mode allows for complete proportioning checks without discharging foam into the environment, reducing waste and minimizing costs for cleanup or disposal. 

A smarter future for foam fire protection 

The move toward smart proportioners reflects a broader industry trend: combining proven mechanical reliability with digital intelligence. Mechanical water-driven proportioners have a long record of dependable performance, operating without the need for electricity and functioning under challenging conditions.

By adding a layer of smart monitoring, operators gain continuous insight into system performance, better documentation and greater confidence.

In high-risk environments – from tank farms to chemical processing plants, offshore platforms to large warehouses – readiness is not negotiable. Smart proportioners provide the assurance that systems are not just installed, but operating within the exact parameters needed to suppress fires effectively. 

In the high-stakes world of fire safety, that’s more than just an upgrade – it’s peace of mind.
