Non-Vented Water Level Sensor and Data Logger Combination

Low-cost Level & Temperature Data Logger

The LevelSCOUT is an absolute sensor, requiring no vent tubes, desiccant, or bellows. It can be paired with a BaroSCOUT barometric sensor and used with the Aqua4Plus 2.0 Barometric Compensation Utility to adjust the LevelSCOUT readings for current atmospheric pressure.

  • Low power—4.5 year battery life

  • Integrated datalogger collects up to 50,000 records

  • Small diameter—0.875″ (2.22 cm)

  • Easily connects with other sensors via RS485 network

  • Includes Aqua4Plus and Aqua4Plus Lite control software



  • Measures level, temperature, and time

  • Thermally compensated—great where water temperatures vary, such as in streams or industrial tank applications

  • ± 0.05% FS

  • Low power—4.5 year battery life

  • 316 stainless steel, fluoropolymer, and acetal construction (titanium optional)

  • Modbus® RTU protocol—for great flexibility


  • Non-volatile memory—your data will not be lost in the event of a power failure

  • Pause logging feature—temporarily pause the logging while repositioning or transporting sensor

  • Delayed start feature—state a specific future start time, making it easy to set several sensors to start at the same time

Cabling & Networking

  • Wireless connectivity

  • RS485 network—allows several sensors to be networked together and provides much longer cable leads

  • Field-serviceable connectors—easily remove the connector, route cable through well seals, walls, or conduit, and then replace connector

  • Available cableless or with a user attachable PU or ETFE cable


  • Comes with free Aqua4Plus and Aqua4Plus Lite control software to get you up and running immediately

  • View your data in real-time

  • Easy export to spreadsheets and databases

  • Barometric compensation utility

  • Update sensor via firmware while in the field—great for future updates

The LevelSCOUT can be utilized in many applications including:

  • Site assessments

  • Tidal studies

  • Environmental monitoring

  • Surface water discharge measurement

  • Aquifer level monitoring

  • Aquifer storage & recovery
