The Milesight EM500-UDL LoRa ultrasonic sensor enables you to monitor the levels of fluid and solid materials. Using ultrasonic waves, the sensor picks up on reflected waves from nearby objects to provide a reliable distance measurement.

Ideal for a wide variety of applications including:

  • Water level monitoring
  • Flood monitoring
  • Level/depth monitoring in tanks
  • Snow level monitoring

The EM500-UDL is particularly useful in Smart Agriculture applications where it can be used to monitor fill levels in grain stores, fertiliser and pellett silos.

Compatible with Milesight’s IoT Cloud solution, users of this LoRa ultrasonic sensor can easily access and manage recorded data from wherever they may be. Housed in an IP67 rated housing, the sensor can be installed in harsh environments.
