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

Low maintenance:
Operation with commercially available 1.5 V baby cells or 3.6 V lithium batteries for service lives of up to 5 years*)
*) depending on measurement and transmission interval. Example: hourly measurement of water level and water temperature, 1 x daily remote data transmission via LTE-M

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

SlimCom 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.

Last but not least:
With the password-protected web portal SEBA Hydrocenter data is not only safe, but also accessible at any time on the road or from the office. Alternatively, there is also the possibility of simple data provision on a secure SEBA FTP server.

  • Construction site supervision, difficult-to-access measurement sites (e.g. underground measurement sites) as well as measurement sites that require rapid data actualisation or are of major public interest
  • 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.
