The standardized 1000-liter IBC is used as a transport, storage, and collection container for a wide variety of liquid process media. Its fill level is an important variable in many applications, but as a mobile unit it cannot be integrated into hard-wired monitoring systems. The Pepperl+Fuchs autonomous IoT wireless sensor WILSEN.sonic measures the fill level of intermediate bulk containers (IBCs) and sends the measured value to the target instance via LoRaWAN. The device is simply screwed into the standardized lid opening.
Transmission of fill level and optional geo-position
The 2-inch external thread of the IBC-WILSEN.sonic fits into the standard opening in the IBC lid. Its measuring range is preset for this application, so parameterization is not necessary. Ultrasonic sensors are virtually unaffected by external influences and the material properties of the medium, and the robust device, which is suitable for outdoor use, reliably delivers measured values with millimetre accuracy. These are transmitted by the integrated wireless sensor node via LoRaWAN.
Depending on the frequency of data transmission, the replaceable battery can last up to ten years. With minimal installation effort previously unmonitored assets can be monitored and communicated with. Current fill level values, including the GPS geo-position if required, are available for process optimization and predictive IBC logistics.
