Overview
The LeveLine collects water level data at user-defined intervals and stores the information in its internal memory. The logger can take up to an impressive 10 readings per second and the huge internal memory is capable of storing up to 500,000 readings. Made from titanium the LeveLine is built for deployment in all kinds of water from fresh groundwater to salty marine waters.
It is constructed with harsh environments in mind and has an ultra rugged titanium body and connectors that are highly resistant to corrosion. The Delrin nose cone reduces fouling of the pressure sensor, which extends the length of deployment, maintains data accuracy and extends the life of the LeveLine.
LeveLine is available with both vented (gauge) and non-vented (absolute) Kevlar reinforced cables that allow for real-time monitoring. For the non-vented version you will also require a barometric pressure monitor, LeveLine – BARO. Each baro logger provides compensation data for multiple water level loggers that are close by.
LeveLine can be connected to our range of Neon, web-enabled, telemetry loggers so that data can be accessed directly from your PC, tablet or mobile device. If you prefer a more hands on approach you can monitor in real time using your laptop or the GPS LeveLine meter.
