E+H Micropilot FWR30 Free-Space Radar Level Sensor

The Endress+Hauser Micropilot FWR30 is an innovative, battery-operated free-space radar level sensor engineered specifically for remote, isolated, and mobile application monitoring. Utilizing an advanced 80 GHz frequency-based time-of-flight measuring principle, this compact non-contact level transmitter delivers precise measurements up to a maximum range of 30 m (98 ft) with an exceptional accuracy of ±2 mm (0.08 in) for liquid applications.

Powered by a replaceable D-size lithium battery (ER34615) and equipped with built-in cellular radio connectivity (LTE-M, NB-IoT, GPRS, EDGE), the FWR30 radar sensor operates entirely independently of external power grids. It automatically transmits critical level, ambient temperature, and device status data directly to cloud platforms such as Netilion Value, Netilion Inventory, or SupplyCare Hosting. This allows operators to track asset inventories and monitor tank levels remotely in real time via web applications or smart devices.

Housed in a rugged IP66/IP68 and NEMA Type 4X/6P enclosure, the device is built to withstand harsh indoor and outdoor environments. Flexible mounting options—including threaded adapters, pipe/IBC brackets, and wall/ceiling kits—ensure quick and straightforward installation on plastic IBC tanks, metal silos, and unpressurized vessels. Furthermore, integrated GNSS/GPS positioning (depending on device version) allows accurate tracking of mobile assets, making it an ultimate, maintenance-efficient solution for water management, chemical storage, and logistics.

Applications

• Remote Tank & Silo Monitoring: Continuous level tracking of liquids in unpressurized storage tanks, buffer vessels, and isolated industrial sites.

• Mobile Containers & IBC Tanks: Monitoring fluid levels in plastic IBC containers (with tubular cages or mesh frames) and mobile logistics units.

• Water & Wastewater Management: Dynamic water level monitoring, flood control, and remote municipal utility applications.

• Chemical & Process Industries: Inventory management of general liquid media where traditional wired instrumentation is impractical.

FAQ

• Q: How long does the battery last, and can it be replaced?

  A: Yes, the battery is fully replaceable (ER34615 lithium primary battery). Battery life depends heavily on the configured measuring and transmission intervals; for example, with a measuring interval of 1 hour and transmission every 24 hours, the battery life exceeds 10 years.

• Q: How are the measured values accessed by the user?

  A: The FWR30 transmits data via cellular radio to cloud platforms (such as Netilion Value, Netilion Inventory, or SupplyCare Hosting), where users can read measurements, history, and device status remotely via web browsers or apps.

• Q: Can this sensor be used in pressurized tanks?

  A: The device is designed for unpressurized applications or threads with low-pressure limits (up to 1 bar / 6 bar max with PVDF washer depending on specific thread configurations). Always verify pressure limits against the device nameplate.
