Radar Level Measurement Without Complex Wiring
The Micropilot FWR30 takes a different approach to level monitoring. Instead of relying on traditional wired instrumentation and local control infrastructure, it combines 80 GHz radar measurement, battery power and mobile connectivity in one device.
This makes it particularly useful for tanks, silos and other assets where running signal and power cables would be inconvenient or unnecessary.
The radar sensor performs non-contact level measurement, while measurement data can be transmitted to cloud-based services for remote access and monitoring.
One Sensor, Connected to the Cloud
The FWR30 is designed for IIoT applications where knowing the current level is only part of the requirement.
When combined with Endress+Hauser cloud services such as Netilion or SupplyCare Hosting, the device can support applications including digital inventory management, logistics operations and environmental monitoring.
Measurement data can be accessed remotely through a mobile device or desktop computer, reducing the need to visit every measurement point simply to check the current level.
80 GHz Radar for Non-Contact Measurement
The FWR30 uses an 80 GHz radar measuring principle, allowing level measurement without physical contact with the process material.
For liquid applications, the specified accuracy is ±2 mm, while solid applications are specified at ±5 mm. The maximum measurement distance is 30 m for both application types.
This makes the sensor suitable for both liquid storage tanks and bulk-solid storage vessels, depending on the selected configuration.
Built for Remote and Distributed Assets
The FWR30 is especially interesting when measurement points are distributed across a large site or located away from the main instrumentation infrastructure.
The device is battery powered and communicates through NB-IoT or LTE-M, with 2G available as a fallback. This wireless architecture reduces the infrastructure normally associated with conventional level measurement installations.
For mobile assets, the integrated GPS function can also support location verification of measurement points.
Suitable for Tanks, Silos and Mobile Containers
The FWR30 can be used for level monitoring and inventory management of liquids and bulk solids.
For solids, Endress+Hauser specifically lists applications in mobile and stationary plastic and metal tanks, including IBC tanks and storage silos. For liquids, the device is positioned for mobile and stationary storage tanks.
This gives the FWR30 a useful role beyond conventional fixed process instrumentation.
Remote Monitoring for Logistics and Inventory
For companies managing multiple storage locations or mobile tanks, manually checking levels can become a logistical task in itself.
The FWR30 can provide measurement data remotely through the connected cloud platform, making it suitable for inventory visibility and logistics-related monitoring.
For mobile tanks, the integrated GPS function adds another layer of information by helping verify where the measurement point is located.
Useful for Environmental and Water Monitoring
The FWR30 is also specified for dynamic level measurement in open channels and retention areas, including applications related to flood monitoring and stormwater management.
This makes the device relevant not only to industrial inventory applications but also to distributed environmental monitoring points where remote data access is valuable.
Compact Wireless Measurement for IIoT Applications
The strength of the FWR30 is not simply its radar technology. It is the combination of several functions in one device:
Radar measurement → battery power → mobile connectivity → cloud access → GPS
For suitable applications, this can turn a conventional measurement point into a remotely accessible data source without requiring the same level of field infrastructure as a traditional wired installation.
