LNR06V4 radar water level sensor

The level sensors with integrated radar of this new V4 series have been designed for use in the most difficult environments where temperature, tightness and safety are essential. The LNR06V4 sensor is suitable for permanent or temporary installations, for measurements up to 6M. They offer many advantages including ease of installation. Position it in its mounting and set it up remotely by radio

Uses of the LNR06V4-LTE radar level sensor - logger

The LNR06V4 loggers/radar level sensors :

are quality instruments, manufactured at the Ijinus site in Mellac. Robust and waterproof (IP 68 tested at 1 bar during 30 days), they can be installed in outdoor locations, in places exposed to meteorological conditions. They autonomously measure and record water levels in rivers, storage basins or stormwater retention basins, irrigation canal, and at the inlet and outlet of wastewater treatment plants.

The LNR06 radar level logger from Ijinus is an all-in-one system. It replaces the traditional measurement kit consisting of a sensor, a power supply and a PLC for data collection. It is a Plug&Play solution with integrated battery.

Data are available on the Ijitrack web platform and Wiji mobile App, or your own SCADA page  


LNR06V4 applications

The LNR level sensor-logger is based on radar measurement technology. Electromagnetic in nature, the radar wave is not impacted by particular exposures such as wind or temperature variations. The solution is therefore perfectly suited for outdoor use, even when exposed to weather conditions..


This radar level sensor is perfect for monitoring:

  • streams : preventive management of low water and floods
  • rainwater storage or retention basins : monitoring
  • inlets and outlets of wastewater treatment plants : The measurement of water height allows the calculation of flows by conversion, to meet the regulatory obligations.
  • lagoon discharge level and flow monitoring
  • Irrigation Canal radar level measurement
  • Any other needs in water level measurement
