The LeveLine® is a self-contained data-logging device that records water level and temperature continuously during its deployment. It features a highly accurate piezoresistive, ceramic pressure sensor and a temperature thermistor, which are powered for up to 10 years by the internal 3.6V lithium battery.
LEVELINE INTRODUCTION Capture the water level data as quickly as 10 times per second and store up to 500,000 data records on the instrument’s built-in memory. All this technology is neatly sealed within a small, corrosion resistant, titanium housing (22 x 186mm) that can be deployed to measure either absolute pressure (ABS, non vented) or gauge pressure (GAUGE, vented) to depths of up to 500m.
APPLICATIONS• Aquifer characterisation• Stream, lake and river water level management• Hydraulic conductivity / Slug testing • Coastal tide and harbour variation measurement• Long term ground water level monitoring • Construction and mine water level management• Storm water and wetlands research
Tough Delrin Nose Cone

Telemetry availableDiscreet telemetry system available for concealed deployments
Simply plug the QuickDeploy key into the logger’s connector as the unit is deployed to:
• Zero the depth sensor to measure absolute depth from the start
No need for any data correction during the analysis stages after the deployment saving you time and simplifying the analysis process
• Initiate your pre-programmed logging scheme at the exact instant of deployment and check the battery and memory levels are ok
A great feature if the specific deployment time isn't known in advance plus using the LED indicator as a final sanity check for both battery and memory
could save you from a costly, failed deployment
System Breakdown
"The QuickDeploy Key reduces time and complication both pre and post-deployment, making your job easier."
This means loggers can be set up with the desired logging frequencies and stored on the shelf for any given time period. The user can then take the number of loggers they need and initiate logging as they deploy each instrument, into the borehole for example, making the set up and deploy stages much simpler.

LeveLine® deployment set in Google Earth
The hand-held GPS LeveLine® Meter takes the features of the QuickDeploy key and builds on them
• Full on-site logger setup, data retrieval / storage and facilitates live monitoring, which is particularly ideal for pumping operations
Make deployment changes in the field, view live level data - no problem!
• Embed the GPS coordinates in the LeveLine’s memory as it is deployed, so that it appears as part of the dataset upon retrieval.
• Measure barometric air pressure and add a salinity value for auto compensation
• Download data from multiple loggers using the LeveLine Meter
No need to take a laptop out in the field, recover your data in the rain!

GPS LeveLine Meter
Connect the LeveLine® logger to your PC to set up your logging scheme using the LeveLink software:
• Set logging rates in hours, minutes, seconds and sub-seconds
• Set up event triggers for user specified level and temperature changes
• Apply offsets and barometric corrections to logged data
• Produce Google Earth and spreadsheet files at the press of a button
• Displays number of recordings saved in memory and the number of available data points
• Displays the remaining battery of the logger
All Connections Covered
There are various adaptor kits available to keep your system flexible, if you need to update a logging scheme on a logger 20m below the surface on an extension lead, we have an adaptor to allow you to connect it straight to your laptop.
