Ultrasonic Level & Distance Sensor EM500 C100 – Milesight (LoRaWAN)

The Milesight EM500 C100 is an industrial ultrasonic level and distance sensor built for accurate non-contact measurement. Mounted above the target surface, it reads the distance via ultrasonic waves—useful when contact probes are inconvenient, high-maintenance, or unsuitable for corrosive liquids and difficult-to-access assets.

With a 0.25 to 10 m measurement range, the EM500 C100 covers larger tanks and wider monitoring points. Data is transmitted over LoRaWAN (EU868), which is ideal for long-range deployments across outdoor sites and distributed facilities without running cables. Configuration is practical in the field via NFC (mobile app) or USB Type-C (PC software/console), with downlink configuration supported.

Concrete real-world examples:

River level monitoring: track water level changes and trigger alerts when thresholds are reached.

Retention basins and pumping pits: monitor trends, detect rapid level changes, and support maintenance planning.

Industrial water/chemical storage: non-contact tank monitoring to reduce corrosion and cleaning issues.

Large bins and silos: inventory monitoring to reduce manual checks and prevent stockouts.

Outdoor installations: IP67 + UV resistance supports long-term exposure to dust and weather.

Operational features are designed for reliability: on-device data storage (1,000 entries), data retransmission, and data retrieval help keep readings available even through temporary connectivity issues. Alarm options include threshold alarms and change alarms.
