OTT HydroSystems

Complete hydrological gauging stations with telemetry

Description

OTT HydroSystems offer a decisive price advantage compared to individual configured systems. The IP-enabled and highly energy-efficient datalogger OTT netDL is the core of the system. Several SDI-12 sensors may be connected to the rugged logger, as it has up to 40 channels. The measured data may be remotely transferred via the built-in cellular modem, optionally via satellite or Ethernet. The required antennas are already included in the system.

  • Turn-key solutions for stand-alone measuring stations
  • Gauging station, Pole mount
  • Battery, Solar
  • Cellular, Satellite (GOES/Meteosat)

Advantages

Compact, turn-key, and convenient:

  • All components are pre-installed, pre-wired, and pre-configured – minimum installation operations required.
  • Standardized configuration resulting in particularly attractive value for money.
  • Rugged lockable stainless steel system cabinet – particularly designed for field applications.
  • Cabinet enclosure fitted with breathing gland for sufficient ventilation and drainage.
  • Powerful IP datalogger providing efficient power management.
  • Convenient stainless steel mast mounting bracket – for easy installation to masts of 1″… 4″ (accessory).
  • Alternatively stainless steel wall bracket for safe wall mounting, e.g. in gauge station (accessory).

Examples of Use

Quick and easy installation of solar powered hydrological measuring stations:

  • Ideally suited for remote locations
  • Reliable and efficient water level measurement with OTT CBS, e.g. in streams, rivers, canals, lakes, or reservoirs
  • Measurement of water level, discharge, water quality or precipitation using any type of SDI-12 sensor
  • Remote data transfer via GSM/GPRS, 3G, Ethernet, or satellite
