Integrated radar level sensor model LNR06V4

Level logger with integrated radar level sensor and various communication options. Particularly suitable for outdoor measurements (rivers, storm water tanks, etc.). Fully autonomous with long battery life, logger and integrated modem. Easy to install and use, configuration is done securely via direct radio connection.

• On-site wireless configuration and radio data download (Wiji protocol)
• Powered by lithium battery, ultra-low power consumption, ultra-low power consumption
• Memory: 500 000 data
• Communication: locally via radio + 2G / 4G option (LTE-M / NB-IoT)
• Inputs: 1 external power supply (5 ..30 Vdc), 2 contacts 100 Hz, 1 Modbus
• Outputs: 1 power supply (internal battery or switch), 1 open drain, 1 Modbus
• IP68 (1 bar/30 days) rated rugged housing
• Conversion tables and integrated formulas (water head, flow rate, volume)

Suitable for monitoring of:

• Streams: preventive management of low water levels and flooding
• Rainwater storage or retention basins: monitoring
• Inputs and outputs of wastewater treatment plants: The measurement of water height allows the calculation of flow rates by conversion, in order to comply with regulatory obligations.
• Lagoon discharge level and flow rate monitoring
• Radar level measurement in irrigation canals
• Any other water level measurement requirements
