Logger fields of use

You can use this logger for different applications by connecting one or several sensors :

  • CSO monitoring (CSCV3)
  • Lifting station monitoring (Current clips F0A00066 and F0A00046 Overflow detector)
  • Groundwater resource (CNR level pressure sensor)
  • Rainfall (RG20 and RG25)
  • Water height/Flow measurement with pressure sensors (CNR sensor series)
  • Pressure on drinking water pipes (CPA sensor range )
  • Inclinometer sensor (F0T00002)
  • Other sensors with 4-20mA output
  • Flow measurement on drinking water network (connection by 4-20mA on electromagnetic flowmeter)
  • Drinking water meter reading (connection to flowmeter via a pulse unit)

Local device commissioning and configuration by radio

These data loggers are configured locally by radio (direct connection, no need of any activation on the logger) using a HF/USB programming kit to connect to your laptop. This kit also includes the Avelour software offering quick and easy configuration at each step (measurement period, threshold, conversion, data sending …)

Communication by 2G / 4G (LTE-M / NB-IoT)

The LOG03V4 logger measures and records up to 500,000 measurements. It can retrieve data from other Ijinus sensors and loggers present nearby. It will then send all its data to the SCADA by cellular communication.
By choosing a logger with the optional modem card, you can send your data directly to our web platform www.ijitrack.com, or any other server with your SCADA, or simply in .CSV file
