Leveline Loggers

The Aquaread LeveLine Logger range consists of highly accurate, self-contained sub-surface instruments engineered for continuous water level, temperature, and conductivity monitoring. Featuring a premium piezoresistive ceramic pressure sensor housed in a robust, corrosion-resistant titanium body, these units function independently deep down inside boreholes, rivers, and coastal sites. They are designed to collect high-fidelity environmental profiles autonomously and securely over extended deployment periods without external support.

What distinguishes the LeveLine Loggers from standard market alternatives is their complete hardware independence. Each logger contains its own long-life internal lithium battery and a massive non-volatile memory that safely logs up to 500,000 readings. Furthermore, they feature both SDI-12 and RS485 Modbus digital outputs directly on the probe head, allowing seamless data extraction or direct telemetry connection without the need for expensive, proprietary external interface adapters.

Key Features

  • Autonomous Logging & Storage: Features an internal, non-volatile memory capable of capturing and securing up to 500,000 data points with sampling rates adjustable down to 10Hz.
  • 10-Year Internal Battery: Powered by an on-board 3.6V lithium battery, allowing up to a decade of continuous, unattended field logging before requiring replacement.
  • Corrosion-Proof Titanium Build: Encased in a hermetically sealed, 22mm-diameter titanium housing that provides total immunity to seawater, biofouling, and aggressive industrial effluents.
  • Optional CTD Integration: The LeveLine-CTD variant incorporates a highly precise 4-ring toroidal conductivity sensor to capture salinity, density, and total dissolved solids (TDS) alongside standard level and temperature data.
  • Barometric Compensation System: The companion LeveLine-Baro logging unit records atmospheric fluctuations on the surface, allowing automatic, precise barometric compensation via software for all absolute (non-vented) models.
Leveline-BARO Barometric Pressure Logger

Leveline-BARO Barometric Pressure Logger

The LeveLine-BARO Logger records atmospheric pressure in Bar, mBar, psi, kPa, mmHg, inHg, cmH2O and inH2O. It is the preferred method to compensate the absolute data recorded by the Absolute LeveLine sensors. One unit can cover all Leveline sensors within a 10Km radius.
