Leveline

The Aquaread LeveLine range is a highly versatile family of water level, temperature, and conductivity instruments designed for precise, continuous environmental monitoring. Operating with premium piezoresistive ceramic pressure sensors housed in rugged titanium, these instruments are engineered to deliver stable, drift-free measurements in fresh, brackish, or coastal marine waters. The series is split between self-contained logging units that operate autonomously and compact digital sensors designed for direct integration into wider telemetry networks.

What sets the LeveLine range apart is its physical and operational flexibility. By offering both fully autonomous, battery-powered loggers and externally powered, stream-only “Mini” sensors, the Leveline range allows operators to deploy the exact hardware required without paying for redundant features. Additionally, all sensors in the family feature native SDI-12 and RS485 Modbus communications embedded directly inside the probe, eliminating the need for expensive external proprietary adapters.

Features

  • LeveLine Logger & CTD: Fully autonomous, self-contained titanium logging instruments featuring an internal battery with up to 10 years of life and a massive memory capacity of 500,000 logs. The CTD version adds a highly accurate 4-ring toroidal conductivity sensor to track salinity and total dissolved solids (TDS) concurrently.
  • LeveLine Mini & Mini-CTD: Ultra-compact, battery-less variants designed purely for external power setups. Ideal for direct connection to active data loggers or telemetry stations where a smaller physical footprint is required inside tight boreholes.
  • LeveLine-EWS (Early Warning System): A specialised telemetry-integrated system that monitors level variations and automatically broadcasts SMS or email alerts when pre-configured threshold limits are crossed.
  • LeveLine-Baro Logger: A dedicated atmospheric pressure logger used on the surface to capture barometric changes, enabling precise barometric compensation for all deployed absolute (non-vented) sub-surface sensors.
  • Titanium Durability: Constructed with high-grade titanium bodies across all major subsurface variants, ensuring complete immunity to aggressive chemicals and marine bio-fouling.
Leveline Mini

Leveline Mini

The LeveLine Mini series consists of ultra-compact, titanium-bodied water level, temperature, and conductivity sensors designed for direct telemetry integration. Unlike standard loggers, these "Mini" versions feature no internal batteries or memory, streaming real-time data directly via native SDI-12 or RS485 Modbus. The Mini-CTD variant adds a 4-ring toroidal conductivity sensor for salinity tracking.

Leveline Loggers

Leveline Loggers

The LeveLine series features autonomous, titanium-bodied water level and temperature loggers equipped with an internal 10-year battery and 500,000-record memory. The CTD version adds a toroidal conductivity sensor for salinity tracking, while the companion LeveLine-Baro logger sits on the surface to capture atmospheric pressure changes, ensuring precise, software-based barometric compensation for all non-vented deployments with 10Km radius.

Leveline-EWS

Leveline-EWS

The Aquaread LeveLine-EWS (Early Warning System) is an integrated, battery-powered telemetry system that combines a titanium water level sensor with an in-well cellular transmitter. It continuously monitors water levels and automatically broadcasts real-time SMS or email alerts when pre-configured critical thresholds are breached, providing vital, rapid-response data for flood management and remote environmental monitoring.
