Ultrasone afstands-vulstandsensor Milesight EM400-UDL-868M-W050 LoRaWAN IP67 bereik 5 m

Milesight EM400-UDL-868M-W050 is an ultrasonic distance level sensor designed for non-contact measurement of liquid or bulk material levels up to 5 m. Equipped with LoRaWAN connectivity and an IP67-rated housing, the device enables wireless integration into IoT networks for remote monitoring of tanks, silos and open containers. The compact sensor simplifies installation where wired connections are impractical and supports reliable distance readings in a variety of indoor and outdoor environments.

Advantages

The sensor combines ultrasonic sensing technology with LoRaWAN wireless transmission to deliver long-range, low-power remote readings without physical contact with the measured medium. IP67 ingress protection ensures resistance to dust and temporary immersion, reducing maintenance needs and protecting electronics in harsh environments. A maximum measuring range of 5 m makes this model suitable for small to medium storage vessels while the compact form factor and wireless operation reduce installation time and infrastructure requirements.

Suitable for

• Remote level monitoring of liquid tanks and reservoirs
• Inventory control in silos and small bulk-material containers
• Open container depth or distance measurement in outdoor installations
• Integration into LoRaWAN-based IoT systems for telemetry and alerts

Key specifications

• Measurement principle: ultrasonic non-contact distance sensing
• Maximum measuring range: 5 m
• Connectivity: LoRaWAN wireless communication
• Ingress protection: IP67
• Typical use: level and distance measurement for tanks, silos and open containers

How to use

Mount the sensor above the measured surface with a clear acoustic path to the medium and orient the transducer perpendicular to the surface for accurate readings. Configure LoRaWAN network settings according to your gateway and server requirements, then register the device on the network to begin data transmission. Positioning should avoid obstructions and heavy turbulence at the measurement point; follow mounting height guidelines so the target falls within the 5 m measurable range.

Recommendations

For reliable measurements, ensure the sensing path remains free of heavy foam, dense aerosols or obstacles that can absorb or reflect ultrasonic waves. Verify LoRaWAN coverage at the installation site and perform periodic checks of the housing seals and mounting to maintain IP67 protection.
