Esders GmbH

Esders GmbH — Night-time acoustic leak-noise corpus from wireless correlating noise loggers: qualified per-logger night noise measurements transmitted autonomously over mobile networks (roaming eSIM, best-network selection) to a central cloud server, where they are automatically cross-correlated against GIS pipe data — layout, material properties and diameters — to localise leaks. Each detection is followed by repair, often within 24 hours, producing a tightly coupled measure-detect-excavate-verify loop. Validated by a scientifically accompanied pilot at IWB, the public supplier for the canto…

Esders GmbH offers (Alternative, Geospatial) — Est. nightly acoustic captures per logger across the installed base: each logger records during the night window and transmits daily, so 33 loggers in the documented pilot yield roughly 12,000 qualified captures a year, and a fleet in the hundreds of loggers yields hundreds of thousands annually with a multi-year retention window. Frequency-domain captures are byte-heavy, so the acoustic archive is measured in gigabytes to terabytes per deployment — substantial for a small installed base, and dense because it is nightly, continuous and paired with GIS attributes.

Training acoustic leak-classification models on low-magnitude quiet leaks rather than only large bursts; cross-correlation localisation models robust to sparse and shifting sensor placement; pipe-material and diameter dependent sound-propagation models, valuable because attenuation in plastic mains differs sharply from cast iron; threshold-versus-correlation detector benchmarking data, since both approaches' outcomes exist in the field; sensor-placement optimisation models; and replacing manual night-walking surveys given the acute technician shortage the article documents
