The software enables easy and low-cost documentation of work when carrying out inspections on gas pipes In contrast to GIS solutions, which require a high-quality PC and involve the time-consuming import of pipeline data, Pi Note is a GPS datalogger for Android terminal devices, that enables easy logging of damage, defects and photos. Continuous recording of gas concentrations is possible via a Bluetooth data connection to the Esders measurement devices ELLI, GOLIATH and HUNTER. Positions where a specified alarm threshold was exceeded are recorded and registered separately. The route and the positions of data recordings and alarm thresholds being exceeded are marked in a map.The recorded data can be turned into a report in PDF format with minimal work. For this, the inspection data is marked in the overview list and transferred to the PC via e-mail. The measurement file in the attachment can be read in via drag and drop and all relevant data is available to view on the PC in a clear format. The data can be exported in CSV format to enable customers to carry out further evaluations flexibly according to their own requirements. This means that the trail of the inspection or the position of damage locations can be imported easily in the existing GIS systems- Bugfix for Android 11
