The Levelogger 5 LTC combines conductivity, pressure and temperature sensors in one compact device. 


It combines a datalogger, 8-year battery, Hastelloy® pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 7/8" x 7.5" (22 mm x 190 mm). A Titanium ceramic PVD coating protects the body against corrosion. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal maintenance sealed LTC Levelogger Edge is simple to clean and calibrate, even in the field. Using Levelogger Series Software, it displays conductivity, temperature, and temperature-compensated water level. Memory is non-volatile and stores up to 27,000 sets of readings. See the Model 3001 Edge datasheet for more information on the Levelogger Series of dataloggers, accessories, and software.

Features:

  • Corrosion-resistant Hastelloy pressure sensor
  • Titanium ceramic PVD coating
  • 4-electrode platinum conductivity sensor
  • Single or multi-point conductivity calibration
  • Basic and advanced data compensation options

User-Friendly Operation

Calibration and Data Wizards guide you through the calibration process and barometric compensation, to provide corrected data. Levelogger Software allows you to easily program your preferences, download data, and display data in a graph or table format, or export to other programs. The Real Time View option allows immediate viewing of live conductivity, water level, and temperature readings. Leveloggers are easy to deploy; installation can be with direct read cables or wireline/cord suspension. The LTC Levelogger Edge is SDI-12 compatible using the Solinst SDI-12 Interface Cable. Data can be downloaded in the field using the DataGrabber™ USB data transfer device, or through Bluetooth® using the Levelogger App Interface device. The LTC Levelogger Edge is also compatible with the 9500 LevelSender telemetry system, designed to send your data wirelessly by email or SMS.

Applications

  • Saltwater intrusion and soil salination monitoring
  • Plume remediation monitoring and studies
  • Leachate monitoring at landfills, mine tailings, waste disposal storage sites, and more
  • Agricultural and stormwater runoff monitoring
  • Tracer tests

Biofoul Screen

When an LTC Levelogger Edge is deployed for an extended period, there is the risk of biofouling on the pressure sensor and/or conductivity cell, which can compromise their readings. The Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels, on the instrument sensors. The Biofoul Screen consists of a Delrin sleeve wrapped with copper wire. It simply slips onto the sensor end of an LTC Levelogger Edge, where it is held in place by compression fit.
Using the natural anti-fouling characteristics of copper, the Biofoul Screen is an affordable option to lengthen the time an LTC Levelogger Edge can be deployed. It reduces site visits and time spent cleaning Leveloggers and improves long-term performance by ensuring accurate sensor measurements.            


An optional Biofoul Screen provides extra protection for the Levelogger 5 LTC pressure and conductivity sensors in harsh environments

Levelogger 5 App Interface

The Solinst Levelogger App is designed to communicate to Solinst dataloggers via your smart device. Programming options include start/stop, data downloading, linear and real-time sampling, future start/stop, and GPS coordinates.

The Levelogger 5 App Interface uses Bluetooth wireless technology to connect with your smart device running the Solinst Levelogger App. Use our Levelogger 5 App Interface and a Solinst direct read cable to communicate to a downhole Levelogger and email data files right from the field.
