Water Survey Tech

Product Detail

RDT module SlimCom IoT LR

  • emote data transmission via LoRaWAN™ technology
  • The option to connect (modular system) SEBA data collectors with sensors for measuring water level, water temperature and conductivity
  • Long battery life
  • Slim design (installation starts from a pipe diameter of 2“)
  • Suitable for above- and below-ground monitoring stations
  • Existing SEBA data collectors (Dipper-PT/Dipper-PTEC) can be easily retrofitted
  • Highly reliable in operation thanks to redundant energy supply and
  • XXL buffer storage

Low power consumption through intelligent power management = higher battery life = lower maintenance intervals = lower operating costs.

Low maintenance:
Powered by standard 1.5 V size C batteries. The battery replacement is carried out in no time without any tools.

Ideal for small diameter pipes and for underground measurement sites; comparative measurements with an electric contact gauge can be performed without removing the SlimCom IoT-LR.

SlimCom IoT-LR can easily be combined with Dipper-PT/PTEC to provide a remote measuring station transferring data directly to your workplace.  Where reception is poor, or in locations where underground installation is required, a variety of different antennas are available.

  • Monitoring of retention basins and watercourses
  • Monitoring of groundwater measurement stations starting with a 2″ pipe diameter
  • Cost optimisation by reduction of measurement site visits.
