“…Studying pipe vibration is important for utility pipelines because over a long period of time the vibrations can result in fatigue loading and eventually lead to pipe failure. Research has been conducted to measure fluid flow in utility pipelines using accelerometers [4][5][6][7][8][9][10]. The study of vibration in flexible pipe like a fire hose has received much less attention.…”

A wired sensor network was created to measure water-flow rate in a fire hose. An integrated electronic piezoelectric (IEPE) accelerometer was chosen as the sensor to measure the flow rate based on the vibrations generated by water flowing through a fire hose. These sensors are small, lightweight, and they can be attached to the outside of the hose, not obstructing the water's flow path. A relationship was determined between the flow rate of the water and vibration detected by the accelerometer for a range of flow rates. The raw acceleration signal was used to calculate two metrics: the dominant frequency and the standard deviation of acceleration. In a future study, the relationship between the dominant-frequency metric and the flow rate will be applied to a wireless accelerometer network. The relationship will be used to determine the real-time fire hose flow rate critical for improving situational awareness on the fireground.

“…Vibrations from fluid or gas flow can occur in any relatively rigid pipe such as water, oil, and gas utility or industrial pipes. Wired sensors, including accelerometers, have been attached securely to the outside surface of rigid pipes to measure fluid or gas induced pipe vibrations to determine flow rate within the pipe in research settings as well as in the utility pipeline industry [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…A detailed literature review was included in the previous technical report [23] describing past work focused on detecting vibration from flowing water in relatively rigid pipe using sensors like accelerometers [24]. Standard deviation of acceleration increased as flow rate increased in rigid pipes [8][9][10][14][15][16]. This relationship was found to be similar for flexible fire hose at lower flow rates, from 0 LPM to at least about 300 LPM (80 GPM), however at higher flow rates, above 300 LPM (80 GPM), the standard deviation of acceleration became unpredictable, often peaking and decreasing [23].…”

A wireless sensor network was created to measure water-flow rate in a fire hose. An integrated electronic piezoelectric (IEPE) accelerometer was chosen as the sensor to measure the flow rate based on the vibrations generated by water flowing through a fire hose close to the hose nozzle. These sensors are small, lightweight, and they can attach to the outside of the hose, not obstructing the water's flow path. A relationship between the dominantfrequency metric and the flow rate was applied and used to determine real-time water flow in a fire hose critical for improving fireground situational awareness. A nearly monotonic relationship of flow rate to the dominant frequency was established and then used in a custom graphical user interface for quick, real-time, visual referencing by fire personnel of flow rate in a fire hose. While more work is needed, such as improved physical robustness of the sensor-node assembly and increase robustness of the signal metric, this preliminary study showed the potential of a "smart" fire hose for improved situational awareness during a fire attack.

“…Among the many accelerations sensors available, the selection focused on MEMS accelerometers, which are known for their small size, low costs, and their ability to sense over a relatively large bandwidth, starting from very low frequencies. This approach has proven to be promising in (Khulief, et al, 2012), (Mistretta, et al, 2018), (Restuccia, et al, 2023) and(Lo Valvo, et al, 2023).…”

Abstract. Water Distribution Networks are known to lose a consistent percentage of drinkable water due to the presence of leakages. In this paper it is proposed a solution to detect water leaks consisting of: i) a new sensing equipment able to acoustically monitor the external surface of a newly laid underground pipe; ii) a training of several machine learning models able to analyse the data collected by the new sensing equipment; iii) a user dashboard to give the final user the possibility to monitor the pipe’s condition. The research process included the generation of artificial leakages capable to produce a suitable dataset necessary to properly train machine learning models onto.
