In many industrial plants, small gas leaks and abnormal mechanical sounds are difficult to detect early. Pumps, pipelines, valves, compressors, and other running equipment often create a noisy environment, making it hard for maintenance teams to identify where a problem is coming from.
At a factory in southwestern Italy, the customer wanted to inspect several key areas of the site without interrupting normal production. The goal was to locate possible gas leaks, identify abnormal mechanical noise, and understand the potential cost impact of the detected leakage.
For this field inspection, the team used our HA3 acoustic camera.
The inspection covered multiple areas inside the factory. In the pump room, the acoustic camera was used to scan around pipelines, valves, joints, and running equipment.
The environment was noisy, but the camera made it possible to separate abnormal sound sources from the general background noise.
In another part of the factory, the team also carried out inspection work at an elevated position. This helped check equipment and pipeline areas that are not always easy to access during daily inspection routes.
Inspection from an elevated area of the plant, helping the team locate abnormal sound sources around higher-level equipment and pipelines.
During the inspection, the acoustic camera helped identify several abnormal points, including:
Instead of relying only on listening experience or point-by-point checks, the team could see the location of the abnormal sound directly on the camera screen. This made the inspection faster and easier to communicate with the customer’s maintenance staff.
The acoustic image helped the team quickly confirm the direction and location of abnormal sound sources and caculated the loss of each year.
During the inspection, HA3A helped identify several abnormal points, including:
Instead of relying only on manual listening or time-consuming point-by-point checks, the maintenance team could see the direction and location of each abnormal sound source directly on the acoustic camera screen.
One of the most valuable parts of the inspection was the leak cost estimation function.
Based on the gas price provided at the site, HA3 estimated that one detected leak point could cost approximately €4,772 per year if left unrepaired. This gave the customer a clear financial reference, making it easier to prioritize maintenance work and evaluate the return on inspection.
For the maintenance team, the result was not just “there is a leak here.” It became a visible and measurable issue: where the leak was, how serious it was, and how much it could cost over time.
The factory environment included running pumps, moving equipment, and general production noise. HA3`s acoustic imaging and advanced algorithms helped detect abnormal sound sources even under noisy conditions.
The advanced algorithm design made the inspection process more intuitive. Operators could scan the area, view acoustic results in real time, and quickly understand where attention was needed.
HA3A supports leak cost estimation based on on-site gas price information. This helps customers connect technical findings with real operating costs.
The inspection was completed while the equipment remained in operation. No contact with the equipment was required.
With visual acoustic results and cost estimates, the customer could prioritize repair work more clearly and take action before the issues developed into larger problems.
This field application in southwestern Italy showed how the HA3 acoustic camera can support real industrial maintenance work in noisy factory environments. During the inspection, HERTZINNO helped locate multiple gas leaks and one abnormal friction source, while also providing cost estimation for the detected leakage.
In one case, a single leak point represented an estimated saving of approximately €4,772 per year, based on the gas price provided on site.
For industrial facilities looking to improve gas leak detection, reduce inspection uncertainty, and support predictive maintenance, HA3A provides a practical, visual, and data-driven solution for daily maintenance and safety inspections.
