Well

A continuous level sensor measures the water level in the well and passes it to software on an ongoing basis. At Kögelhof, this is the ifm LR3020 sensor, combined with the E43380 coupling plate and a two-metre E43353 probe rod. In moneo, the available water volume is also calculated from this, but only when the level changes. The values can be viewed from anywhere.

IoT reports the well's water level continuously and warns before it becomes critical. At Kögelhof in Mochenwangen, the farm, the biogas plant and the household depend on a spring a few hundred metres away. The ifm io-key transmits the values via cellular network to moneo, with power from a photovoltaic module and a battery. At critical levels, the farm manager can save water or switch to the municipal supply.

Via a LoRaWAN network that bridges long distances with little energy. In Oberzent, the energy supplier Entega built such a network because most sites have no mobile reception. Endress+Hauser integrated the 19 stations into Netilion, and WAGO gateways process the signals from different measuring devices. Status messages from the devices also show which measuring points need maintenance.

IoT records levels and abstractions automatically and provides them in the formats the authorities require. In Oberzent, water abstractions must be logged and submitted to the regional council. Previously, four water masters drove to the sites and entered the values from flow, level and pressure devices into lists by hand. Today, Netilion produces logs and evidence and reports anomalies by alarm.
