PT2X Smart Water Level, Temperature Sensor and data logger

For Periodic or Long-term Water Level and Temperature Monitoring

Water Level Logger, Vented or Non-Vented Version.

Water Level Logger, Vented or Non-Vented Version.


Measure, water level, pressure and temperature accurately and reliably with the Seametrics’ PT2X Smart sensor and integrated data logging capabilities

316 Stainless steel, fluoropolymer, PTFE construction enables the PT2X to provide highly accurate readings even in rugged or corrosive environments.


  • Integrated datalogger collects up to 520,000 records

  • Thermally compensated for volatile conditions

  • Easily connects with other sensors via RS485 network

  • Includes Aqua4Plus and Aqua4Plus Lite control software

Features - Sensor

  • Measures pressure, temperature, and time

  • Available in absolute, gauge, or sealed gauge

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

  • ± 0.05% FSO typical accuracy

  • Low power—2 internal AA batteries

  • External power options (12 VDC) with AA’s acting as backup

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

  • Available for both Modbus® and SDI-12 protocol

Features - Data Logger

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

  • Flexible, multi-phase logging sequences—measure at your specified intervals and save instructions to disk for reuse

  • 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 variety of cable options, including polyethylene, polyurethane, and FEP


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

  • View your data in real-time

  • Easy export to spreadsheets and databases

  • Barometric compensation utility for use with absolute sensors

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