In 2020, VEGA introduced self-sufficient level sensors to digitise and simplify the measurement of bulk liquids and bulk solids in individual vessels, accurately down to the last drop. By doing so, it became clear that battery-powered radar sensors could easily provide and facilitate integration into IoT (Internet of Things) projects for manufacturers and logistics service providers.
Centralisation and digitisation of processes and infrastructure along the supply chain offer various benefits.
Smart networks are an essential part of the industrial IoT. In the past, plant operators, logistics companies, suppliers, and manufacturers of reagents, additives, and other chemicals did not have an accurate overview of their product inventories.
This was due to the challenge of measuring materials stored in vessels using traditional measuring equipment, which often led to inaccurate inventory records.
One of the main reasons for this is that traditional measuring technology relies on cables and electricity, which may not always be economically feasible or available.
The VEGAPULS-Air series includes self-sufficient radar sensors that offer accurate measurements with a scalable solution for various measuring and logistics tasks.
These sensors use high-performance 80 GHz radar technology, are energy efficient, and provide optimised measuring performance with radio data transmission.
One notable feature of the VEGAPULS-Air sensors is their ability to reliably measure and wirelessly transmit fill levels for up to 10 years.
This capability is useful in various scenarios, such as measuring fill levels in storage tanks containing chemicals, monitoring cleaning agent containers that require regular exchanges, or tracking residual material containers awaiting collection
The VEGAPULS-Air sensors can be attached to the outside of intermediate bulk containers (IBC) to measure the fill level without opening the vessel.
When stacked on each other, VEGA sensors can record individual container current fill levels and positions several times daily and upload this data wirelessly to the cloud.
The devices transmit the measured values via the NB-IoT, LTE-M, and LoRa standards. VEGA utilises a multi-communication model, equipping the sensor with several low-power radio standards and using the standard that’s available at the time. Also, future standards can seamlessly be integrated.
The networking and automation of logistics processes across entire supply chains can be complex. Clemens Hengstler, Product Manager for Digital Solutions at VEGA, explained that large IoT projects often fail due to overly ambitious plans and the attempt to implement everything at once.
Hengstler suggests that a more successful approach would be to proceed step by step.
VEGA offers a scalable solution in which assets are first equipped with VEGAPULS Air sensors that will transmit the measured values to the VEGA Inventory System.
The software would then determine optimal order quantities based on the data received and trigger an order in the ERP system.
This keeps the implementation effort low and allows for a gradual analysis and adaptation of existing processes to create value through optimisation.
Once these processes are functional and tested, they can be integrated into ERP systems such as SAP.
“There is great potential in utilising automation and IoT in processes where fill level plays a critical role. Customers can use fill-level sensors and the VEGA Inventory System to make logistics more efficient and demand-oriented. This leads to greater profitability and helps to reduce the CO2 footprint,” says Clemens Hengstler.
Most companies today experience challenges with inventory management and level measurement in tanks and silos, as those are not equipped with measuring technology because wired installation of sensors would be too expensive.
With the VEGA self-sufficient radar sensors and the VEGA Inventory System in place, companies can now optimise processes and save on resources.
