Smart Wastewater Solution

Best Wastewater Sensor Devices for sewage and wastewater level management.

Wastewater level and Tilt Sensor

Wastewater sensor technology for monitoring and management of wastewater levels in private and public sewers and cesspit tanks.


Wireless sensors can continuously monitor wastewater levels in sewers and cesspit tanks, thus enabling efficient sewer network management. 


Benefits include:

  • optimized and adaptive emptying schedules,

  • better route planning,

  • driver personnel management,

  • wastewater overflow prevention,

  • the anticipation of cleaning/maintenance actions,

  • identification of leaks,

  • owner peace of mind and satisfaction.

Key Features

  • Reliable and accurate, absolute sensing technology.

  • Device is potted for added reliability and security.

  • Superior device materials and design to withstand the harsh environment inside cesspits.

  • Small device for flexible installation options for all types of cesspit setups.

  • Replaceable batteries.

  • Flexible antenna configuration for connectivity in locations with poor network coverage.

  • Latest NB-IoT Technology for nationwide reliable communication with longest battery life.

  • Remotely configurable over the network or locally through Android mobile application.
