Water level sensor CNR
Level sensor in piezometerLogger with buit-in battery, 2G/4G data sendingWater level sensor for groundwater monitoring

Relative pressure sensors CNR

  • Measuring range from 0 to 50m H2O
  • Connection to data logger LOG V4 with or without integrated modem
  • Batterie powered logger, autonomy > 5 years
  • Compact size and discret, rugged system
  • Communicating : HF /GSM / GPRS / 2G / 4G
  • Wireless setting with Rfid technology
  • Certifications : CE / ROHS / ACS(option)
  • Sealing IP68 (1 bar/30 days, if our bracket is used : H0T00060)

The pressure level data logger is fully autonomous, very practical for various applications. The programming is done very easily by radio and includes, depending on model, a modem for automatically send data and alert to the supervision.

Pressure level sensors CNR series

The level sensors from the CNR range easily connect to LOG V4 data loggers on connector
Configuration and retrieving data are done locally by radio with USB / HF programming stick, which integrates our software. If you opt for a logger with built-in modem, you can automatically send the data, reports and alerts to a compatible SCADA like Topkapi, Lerne, Panorama, Dev I/0 – OPC, Floee or to our web monitoring platform : Ijitrack.com.

The CNR series has 3 versions :

CNR serie with M12 8pts connector for a quick connection with the logger LOG V4
CNRT serie provides pressure & Temperature with M12 8pts connector for a quick connection with the logger LOG V4
CNRN serie with bare wire ends The above series include an atmospheric pressure aerators.

Wireless data logger to choose from :

LOG03V4 : 4-20mA – DIGITAL / Connector on the side
LOG09V4 : 4-20mA – DIGITAL / Connector at the bottom
These loggers have the added advantage to connect to other sensors and have their own functionalities.

Radio configuration kit :

HF / USB stick kit WijiKey (includes the software Avelour 6), about 20m radio range
HF / USB kit Wiji (includes the software Avelour 6), about 100m radio range


Environmental applications

  • Autonomous and communicative solution for groundwater monitoring. It is also possible to pair the logger to a rain gauge by radio
  • Level monitoring in tank …
  • V notch weir with conversion water height / flow measurement
  • Pressure sensor with bare-wire ends to connect to PLC
