Case Study – Sprinkler Monitoring System via UNS

Global Pharmaceutical company with revenues of over $11 billion has a core business of prescription drugs with a focus on areas of urology, immunology, cardiology and infectious diseases. New advanced sprinkler monitoring system product created as part of the “Nucleus” Smart Factory Gallarus offering.

Industry 4.0 Digital Transformation

Sprinkler Monitoring System via UNS


In the face of operational challenges and the need for preventative maintenance related to a Corrective and Preventive Action (CAPA), an $11 billion turnover pharmaceutical company sought Gallarus’ expertise to address a pin hole leak in their finished goods warehouse’s sprinkler system. It’s critical to remember these challenges did not just arise, rather utilities are tasked with these operational challenges every day, many of which have financial and regulatory implications. Let’s delve into how this new cutting-edge solution sparked unprecedented results and the benefits achieved through advanced monitoring with real time data.

Current State

The sprinkler system has a distributed pipe network in their production facility and is major a fire protection method, consisting of a water supply system, providing adequate pressure and flowrate for the purpose of fire suppression. A leak at the highest point of the 17m high warehouse, coming down through all the racks and material would cause a lot of damage before it reaches the floor. Even if the client had traditional leak detection software it would take 5-10 days for that to be triggered. The impact of that type of damage on the material would be huge to the company. The company spoke to their sprinkler system vendors who pointed them towards the traditional leak detection solutions on the market. However, the client needed a creative solution as nothing was available on the market to address all requirements.


Gallarus were tasked to provide a real time sprinkler system monitoring solution (via the Unified Namespace) supporting utilities to have visibility into pipe leakage. This solution needed to provide preventative maintenance, gathering anomaly data including changes in stable state ultimately reducing costly failures in their controlled license environment where there is risk of high value product contamination and impacts to site compliance from such failure. Leakage and pipe failure monitoring relies on engineering inspection and judgment and possibly assumed degradation factors for failure prediction. Enter the Unified NameSpace to provide real time data and solve these requirements.

In a number of weeks Gallarus provided a proactive stateful monitoring of the warehouse sprinkler system to baseline the environment of the deployment and from that point on detect anomalies. This allowed the implementation of a preventative maintenance solution to get visibility of potential issues before they happen, detection of anomalies as they happened and identify the possibility of a leak in the system and alert the team.

The solution was tracked by software based on an MQTT lightweight communication protocol that reports by exception only, to exchange data within an Industry 4.0 data ecosystem for easy plug in and out called the Unified Namespace (UNS). The hardware solutions included vibration/acoustics sensors for leak and impact detection, humidity and temperature sensors for real-time environmental monitoring, and an accelerometer sensor for advanced vibration analysis. Additionally, Gallarus deployed server and firewall infrastructure alongside software tools like Ignition for data connectivity, Canary as a data historian, an MQTT broker, cybersecurity measures, and a GUI for user-friendly access to key data points.

Successful tests and simulations on leak detection and change in stable state were completed. Testing was carried out on installed sensors to determine baseline values for setting alarm levels for leak and impact detection. This all provided real time alerts and stateful data at the fingertips of the team.

    New State: Validated Monitoring System via UNS

    Following a successful and validated deployment of a UNS implemented monitoring system, the following are layout screens displayed real time values of the monitoring system from custom designed User Interfaces on desktop, tablet and mobile for Operations Management.

    2. Trends of record temperatures for installed sensors – ability to adjust the historical time frame and also select individual sensor values
    3. Trends of recorded humidity for installed sensors
    4. Historical ASL values from AE sensors
    5. Temp and Humidity sensor values
    6. Recorded Humidity values


    The pharmaceutical company widely recognized the significance of the implemented solution, particularly in preventing extensive damage caused by leaks. Traditional leak detection software would have taken days to trigger an alert, resulting in substantial material loss into the millions. The UNS-based monitoring system, combined with machine learning and AI capabilities, allowed for the detection of anomalies and unusual patterns, facilitating early leak detection, and greatly reducing the risk of any product contamination. The UNS was the heart and soul of the project because the monitoring system was designed so it would learn over time all the operational factors within the warehouse such as doors opening, AHUs turning on, build up patterns and use machine learning and A.I. to detect unusual anomalies. The client is now extremely confident that if they have a leak, they can detect it before any damage occurs. The way it is set up it will either hear the leak or detect it through very sensitive relatively humidity sensors.

    Benefits include 

        • Early detection of any pipe anomalies.
        • Proactive stateful monitoring of the warehouse sprinkler system.
        • Machine learning and AI for predictive maintenance.
        • Prevention of product contamination caused by leaks.
        • Real time alerts to the team.


    Engineering Facilities Manager

    “I recently had the pleasure of working with the team from Gallarus Industry Solutions. The team impressed me with their exceptional problem-solving skills and innovative approach. From the very beginning, they demonstrated a clear understanding of the issue I presented to them, and their expertise was evident in the solutions they proposed and delivered as part for the engagement.

    What really set this company apart, however, was their ability to deliver solutions that not only creatively utilized cleverly deployed sensor technology but also harnessed and optimised existing system performance data. The resulting feedback allowed me to make informed decisions about the direction of my operations and helped me to optimize my processes in ways that I never thought possible. The UNS and new sprinkler and pipe monitoring system has so much more functionality.

    What Gallarus has done is extremely effective and adds a lot of value to our operations. This was not available beforehand or off the shelf, so it is a great success to all parties involved to bring something innovative to the market.”

    Future and Next Steps

    Building on the foundation of the validated UNS implementation, captivating opportunities come into view for utilities and all departments in the business. Further rollout considerations include pump sensors, pressure reading, flow sensors, multi-access motion sensors, water level sensors, and cameras for leak detection at weld points. The flexibility and modularity of the UNS infrastructure also paves the way for future expansion into critical areas such as laboratories, utilities, and operations. The success of the solution demonstrates the transformative potential of Industry 4.0 in the pharmaceutical industry, emphasizing the importance of advanced systems and proactive monitoring for enhanced operational efficiency and compliance.
