(Ground)water level loggers

To measure groundwater levels, we offer efficient groundwater level loggers that can be placed in a monitoring well. These loggers record the water level at fixed intervals over long periods of time. You can transmit this data via telemetry or Bluetooth for further processing.

We offer two types of systems:

  • A telemetry version: ElliTrack
  • A standalone version: LevelStick

Telemetry version

The ElliTrack consists of a transmitter and a sensor that are placed in a monitoring well.

The logger sends data at set intervals via a GSM modem to the ElliTrack.nl portal.

ElliTrack

Our data loggers are known for:

  • Excellent price–performance ratio
  • In-house development, production and sales
  • A local display for easy reading of key data
  • Pressure-compensated measurements for direct water level data
  • Built-in data verification to prevent errors
  • Immediate alerts via SMS or email when thresholds are exceeded

The new ElliTrack D+

The next step in groundwater monitoring

With the ElliTrack D+, we introduce a new standard in reliability and smart technology. This next-generation logger builds on real-world experience and is ready for future technology, including the transition to 4G.

Why choose the D+ version?
While our current models still perform well, the D+ lets you benefit from the latest advances in electronics and sustainability.

Key improvements:

  • Optimised electronics: even better resistance to temperature and external influences
  • Improved antenna for stable mobile connectivity
  • Compatibility with your current systems
  • Smart upgrades: during maintenance, PCB boards are automatically replaced with the latest technology.

These upgrades place the D+ in a higher quality class. It’s a sustainable investment in reliable data for the future.

Available now.
All new orders and repairs are now fulfilled with the D+ model.

Standalone version

The LevelStick also consists of a sensor and transmitter, but has the unique ability to be read wirelessly via Bluetooth.

Its small size allows local readout via mobile phone or tablet, with no need for cables, connectors or USB ports.

You can also use a BLE Gateway to access measurement data remotely. This makes the system highly flexible.

LevelStick

Highlights of this logger:

  • Compact housing for easy installation
  • App available for both iOS and Android
  • Replaceable battery with long lifespan
  • No connectors or USB cables required
  • Over 100,000 installations worldwide

Do you want insight into groundwater levels?

We offer two telemetric options: One for easy installation in a tube well, and one for use in a standpipe. And we offer one standalone option, the Levelstick, which can be made into a telemetric solution with the BLE gateway. Choose between pressure-compensated or absolute sensors.
