Envco – Environmental Equipment

The Levelogger Edge is a self contained water level datalogger, using infra-red data transfer powered by a 10 year lithium battery, offering the flexibility of installing by use of a Direct Read Cable, wireline or Kevlar cord. The Levelogger Edge has a memory capacity of 40,000 temperature and water level data points, or up to 120,000 using the new compression algorithm in linear sampling mode.

Enhanced Features
• Corrosion resistant Titanium based PVD coating
• New robust Hastelloy pressure sensor
• Improved temperature compensation and thermal response time
• Faster communication and downloading speeds with new high speed Optical Reader
• Memory for up to 120,000 readings
• Streamlined software with more sampling options
• Multiple data file barometric compensation

The Levelogger Edge features a wider temperature compensated pressure range (0 to 50ºC, -10 to 50ºC for Barologger Edge), and improved thermal response time. The Hastelloy sensor can withstand 2 times over-pressure without permanent damage.

Applications
• Aquifer characterization: pumping tests, slug tests, etc.
• Watershed, drainage basin and recharge monitoring
• Stream gauging, lake and reservoir management
• Harbour and tidal fluctuation measurement
• Wetlands and stormwater run-off monitoring
• Water supply and tank level measurement
• Mine water and landfill leachate management
• Long-term water level monitoring in wells, surface water bodies and seawater environments

Improved Software
The new Levelogger PC Software is more streamlined, making it easier to program dataloggers, and view and compensate data. The software has more useful programming options, including compressed and repeat sampling, and a future stop option. Data compensation has been simplified, and allows multiple data files to be barometrically compensated at once. Communication speed between the Levelogger Edge and the PC has increased with the new Optical Reader, making downloading data faster.

New Levelogger Software Version 4.0, written to support the new Levelogger Edge, Levelogger Junior, LTC Levelogger Junior, Rainlogger, Leveloader and is backwards compatible to support the Levelogger Gold series. Version 4.0 offers many new features, including the ability to barometrically compensate multiple Levelogger data files simultaneously.

Sampling Modes:
• Linear, Event & User-Selectable with Repeat Mode
• Future Start
• Future Stop
• Real-Time View
• Measurement Rates: 1/8 sec to 99 hrs
