Leveline Mini

The LeveLine-Mini Series features ultra-compact, professional-grade sub-surface sensors designed to capture highly accurate hydrologic data across diverse groundwater and surface water networks. Operating as external-power transducers, these units utilise a premium piezoresistive ceramic pressure sensor to continuously stream fluid height and temperature profiles directly to an existing monitoring network. They are engineered specifically for applications where localised data logging is handled by external telemetry or PLC infrastructure, maximising cost-effectiveness per deployment site.

What the LeveLine-Mini series offers over traditional sub-surface loggers is an uncompromised structural design paired with instant telemetry ecosystem integration. By stripping out the internal battery and heavy memory configurations of larger standalone loggers, these probes reduce their length to a highly deployable footprint while preserving an impressive ±0.05% Full Scale (FS) industrial accuracy. Furthermore, they native-stream open-protocol digital data (SDI-12 and Modbus RS485), allowing immediate plug-and-play scaling when utilising Aquaread’s specialised field tools, including the QuickDeploy key, AquaTel telemetry nodes, and BlueLink Bluetooth adapter.

Key Features

  • Dual Parameter Variations: Available in a standard LeveLine-Mini layout for dedicated level and temperature, or a upgraded LeveLine-Mini-CTD layout that integrates a 4-ring stainless steel conductivity sensor for automated salinity and EC mapping.
  • Titanium and Carbon Fibre Construction: Housed inside a highly rugged, corrosion-proof titanium shell with an IP68 depth rating, making the entire series completely immune to aggressive seawater, industrial runoff, and acid mine drainage.
  • Open System Interoperability: Equipped with native SDI-12 and Modbus RS485 digital output capabilities right out of the box, guaranteeing seamless integration with external third-party RTUs, SCADA systems, and industrial PLCs.
  • Flexible Pressure References: Provisioned in both Absolute (non-vented) models for streamlined deep boreholes and Gauge (vented) variants for real-time mechanical barometric pressure balancing.
  • Modular Field Ecosystem Accessories: Operates natively with the QuickDeploy Key for PC-free zero-point indexing, the AquaTel Telemetry Hub for standalone 4G cloud broadcasting, and the BlueLink Adapter for smartphone monitoring.

Applications

  • Groundwater Borehole Assessments: Long-term continuous depth monitoring in deep wells, municipal aquifers, and mining drawdowns.
  • Estuarine Saltwater Intrusion Tracking: Utilising the CTD sensor model to capture real-time tidal influxes and soil salinisation trends in coastal wetlands.
  • Early Warning Catchment Networks: Integrating directly with telemetric platforms to alert municipal centres of rising waters during severe storm run-off events.
  • Industrial Asset Tank Gauging: Tracking fluid levels and chemical solution balance within harsh, high-corrosion chemical containment cells.
The LeveLine-Mini series integrates seamlessly into a broader data ecosystem tailored to your deployment strategy. For completely unsupervised, long-term installations, the AquaTel Telemetry Hub acts as an autonomous collection station, automatically transmitting high-precision logs via mobile cellular networks directly to your remote database. Alternatively, for active field operations, the portable BlueLink Bluetooth Adapter serves as an ideal on-site monitoring option, allowing technicians to interface with the transducer wirelessly and view real-time data streams instantly on a smartphone or tablet while on site.
Leveline-Mini Water Level Sensor

Leveline-Mini Water Level Sensor

The LeveLine-Mini is a precise water level and temperature sensor designed for diverse groundwater and surface water applications. Encased in a sealed unit, it integrates both temperature and level sensing capabilities. The LeveLine-Mini Absolute employs a durable piezoresistive ceramic pressure sensor, ensuring long-term stability and delivering an accuracy of 0.05%FS across various available level ranges, all of which are temperature compensated from -20 to 80°C. Offered with multiple cable configurations and absolute or gauge options, this sensor requires connection to an external data logger or AquaTel telemetry device for power and data logging, making it a cost-effective solution for water level and temperature monitoring.

Leveline-Mini-CTD Water Level Sensor

Leveline-Mini-CTD Water Level Sensor

The LeveLine-Mini-CTD is a precise water level, conductivity, salinity and temperature sensor designed for diverse seawater and surface water applications. Encased in a sealed unit, it integrates conductivity, salinity, temperature and water level sensing capabilities. The LeveLine-Mini-CTD includes the same piezoresistive ceramic pressure sensor as the Leveline-Mini sensor, plus a 4 ring stainless steel conductivity sensor for EC and salinity measurements. All parameters include automatic temperature compensated from -20 to 80°C. Offered with multiple cable configurations and absolute or gauge options, this sensor requires connection to an external data logger or AquaTel telemetry device for power and data logging.

LeveLine QuickDeploy Key

LeveLine QuickDeploy Key

The Leveline QuickDeploy Key will simplify your fieldwork with Leveline devices and saves you needing to take a laptop to site. It allows users to initiate data logging, perform zero point pressure references in data, ensuring accurate pressure readings against surface air pressure. It can also ensure battery and memory levels are above 10% remaining. Simple LED indication, ensuring task completion and error prevention is simple and quick.
