Wireless level sensors LNU06V3 

LNU06V3  is an all-in-one solution integrating Ultrasonic sensor, logger,  communications and energy in the same device. It allows water height  measurement by aerial ultrasonic, with automatic measurement cycle  changes depending on thresholds, flow rate transformation through  conversion tables, and many other innovative features. Sensors are  equipped with connectors for coupling with an overflow detector, PLC or to  control water sampler. In addition to measuring, these sensors can also  be paired with others equipments located nearby or serve as data  concentrators (for version with integrated communication HF GSM, GPRS, 3G  or Sigfox).

  • Measuring range of 0,3 … 6m (0.98 – 20ft)
  • Wireless setting with Rfid technology
  • Communication options : GSM / GPRS / 3G / Sigfox
  • Inputs : 1x voltage (7V…30V), 2x Contacts 1Hz, Modbus
  • Outputs : 1x switch, 1x open drain, Modbus
  • Memory : 500 000 measures
  • Lithium battery powered, low-power consumption
