Levelogger Edge - 3001 - Water Level Dataloggers

With absolute precision, Levelogger Edge records up to 120,000 water level and temperature data points, using a new linear sampling mode compression algorithm. Improved temperature compensation, reduced thermal response times, accuracy of 0.05% FS, 24 bit resolution with 10 year battery. Corrosion-resistant Titanium based PVD coating and Hastelloy pressure sensor. Levelogger Junior and LTC Levelogger Junior conductivity dataloggers also available.

Increased Stability and Reliability

The Levelogger Edge has improved stability and reliability with the introduction of the new Hastelloy pressure sensor and Titanium based PVD coating. Both elements add increased corrosion resistance in harsh environments, as well as making readings more stable in extreme pressure and temperature conditions.

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.

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

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.

Applications

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

Water Level Datalogger

The Levelogger Edge is a self contained, automatic water level and temperature recording device. It combines a Hastelloy pressure sensor, temperature thermistor, 10-year lithium battery, and a datalogger with FRAM memory for 40,000 sets of data points, or up to 120,000 using the new compressed linear sampling option. All components are sealed within a 7/8' x 6.25' (22 mm x 159 mm) stainless steel housing with corrosion resistant Titanium based PVD coating.

The Levelogger Edge maintains the high resolution of previous Leveloggers, and an accuracy of 0.05% FS. The new, more precise Barologger Edge provides the easiest and most accurate method of barometric compensation.

Battery life is 10 years based on a 1-minute sampling rate. The Levelogger Edge also inherits the Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy and stability, make the Levelogger Edge the most reliable instrument for long-term, continuous water level recording.

Convenient Sampling Options

Leveloggers can be programmed with linear, event-based, or a user-selectable sampling schedule. Linear sampling can be set from 1/8 second to 99 hours.Event-based sampling can be set to record when the level changes by a selected threshold. Readings are checked at the selected time interval, but only recorded in memory if the condition has been met. A default reading is taken every 24 hours if no 'event' occurs.

The Schedule option allows up to 30 schedule items, each with its own sampling rate and duration. For convenience, there is an option to automatically repeat the schedule.

The Levelogger Edge can be programmed with compressed linear sampling, which increases the Levelogger memory from 40,000 to up to 120,000 readings.

Accurate Barometric Compensation

The Levelogger Edge measures absolute pressure (water pressure + atmospheric pressure) expressed in feet, meters, centimeters, psi, kPa, or mBar.

The most accurate method of obtaining changes in water level is to compensate for atmospheric pressure fluctuations using a Barologger Edge, avoiding time lag in the compensation.
The Barologger Edge is set above high water level in one location on site. One Barologger can be used to compensate all Leveloggers in a 20 mile (30 km) radius and/or with every 1000 ft. (300 m) change in elevation.

The Levelogger Software Data Compensation Wizard automatically produces compensated data files using the synchronized data files from the Barologger and Leveloggers on site.

The Barologger Edge uses pressure algorithms based on air rather than water pressure, giving superior accuracy. The recorded barometric information can also be very useful to help determine barometric lag and/or barometric efficiency of the monitored aquifer.

The Barologger Edge records atmospheric pressure in psi, kPa, or mBar. When compensating submerged Levelogger Edge, Gold or Junior data, Levelogger Software Version 4 can recognize the type of Levelogger and compensate using the same units found in the submerged data file (Levelogger Gold and Junior measure in feet, meters, or centimeters). This makes the Barologger Edge backwards compatible.
