The Milesight EM410-RDL uses 60 GHz millimetre-wave radar to measure liquid level from 0.3 to 12 m. Radar is not thrown off by dust, condensation, temperature or acoustic noise, so it suits tanks, sewers, rivers, reservoirs and salt-mist sites where ultrasonic readings drift.
Why pick it
- An 8° beam and up to ±2 mm accuracy on a still surface.
- Corrosion-resistant PVDF body rated IP68, with a G 1½ or NPT 1½ thread for direct tank fitting, or a wall bracket.
- Echo-curve view and one-click diagnostics to calibrate on site, plus 2,000 stored readings with retransmission.
Comes as a LoRaWAN version (about 7 years on one 19000 mAh cell) or a 4G LTE Cat 1 version with a nano SIM (about 5 years), each with internal or external antenna. Configured over NFC or Bluetooth.
Works with any standard LoRaWAN gateway and network server, such as the Milesight UG65 indoors or the UG67 outdoors, with alerts and dashboards on IoT Factory.
For hazardous areas, the EM411-RDL is the same radar with ATEX Zone 0 approval.
