3001 Levelogger Edge | Water Level Logger

Solinst Canada

Solinst Levelogger Edge: Durable, accurate and reliable water level dataloggers

Solinst revolutionised electronic water level measurement when they introduced the Levelogger — the first combined datalogger and absolute pressure sensor — and they are still leading the industry to this day. 

The Levelogger Edge is a self contained water level datalogger — a level logger — using infra-red data transfer powered by a 10 year lithium battery (1 reading per minute), 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 compression algorithm in linear sampling mode.

Telemetry? No problem!

Solinst loggers can be connected to any SDI-12 logger or take advantage of Solinst's own radio telemetry system or the powerful Solinst Levelsender cellular modem.

Quality Accessories for Quality, Cost-effective Data

 Do you want direct access to your logger without removing it from the well? Use a direct read cable to interface with the logger in situ. They come in a range of standard lengths but custom lengths are also available.

The 3001 Barologger Edge provides intelligent barometric compensation for the entire Levelogger Edge, LTC and Junior range.

The Solinst Optical Reader provides a cost-effective means of quickly accessing your logged data directly on your laptop.

What does the pressure range of the water level sensor mean?

This is the maximum depth to which the level logger can be submerged without risk of damaging the water level sensor within it. In reality than can go deeper,  but as a rule of thumb Solinst recommend that if you do submerge the level logger beyond this depth it should not exceed 50% of the rating. So for a M200 (200m rating), do not submerge it beyond 300m.

What does full scale (FS) mean?

What does full scale mean in terms of a water level sensor accuracy? This means that the accuracy is related to the maximum pressure rating of the water level sensor on the level logger. So for example, if you have an M5 (5m rating) then it is accurate to within ±0.25cm, where as an M200 (200m rating) will be accurate to within ±10cm.

How our readings compensation for pressure?

The level sensor readings are automatically compensated for temperature but not barometric pressure (for automated barometric pressure use the LevelVent). A 3001 Barologger Edge is required for barometric compensation.

Absolute vs Vented loggers

Absolute Pressure Transducer

The Levelogger Series of dataloggers features an absolute pressure transducer. Absolute sensors are sealed; therefore, they measure all the pressure they are under, both water (hydraulic head) and air acting on the surface of the water (barometric or atmospheric pressure). As such, data must be compensated for barometric effects to gain hydraulic head measurements only.

Barometric compensation is most easily done using a second datalogger (a Barologger) which records air pressure only. Barometric compensation of Levelogger data is performed using the Barologger data and the Data Wizard in Solinst Levelogger Software.

Vented Pressure Transducer

The Solinst LevelVent and AquaVent feature a vented pressure transducer, also known as a gauged pressure transducer. Gauged pressure sensors are open to the atmosphere by use of a vented communication cable. The cable has a small vent tube, which runs the length of the cable from the surface, and terminates behind the pressure transducer. This vent tube acts as a channel for barometric pressure change at the surface, and allows the barometric pressure on the water column to be cancelled out by the pressure transmitted in the tube. The data is automatically compensated for barometric effects, as well as altitude.

Levelogger Software

3001 laptop 2x

Levelogger Software is user-friendly. It auto-detects the type of datalogger connected, and provides the appropriate programming options. The Datalogger Settings tab provides information about the connected datalogger, including battery level. It is used to set a sampling regime, and start and stop dataloggers. There are options for immediate start or a future start and stop times. Settings files can be saved for easy re-use. Apply the settings files to synchronize all dataloggers in one project.

Data Control is used to download, view, and export data files for use in other software programs. The Real Time View tab is used to actively view data as it is being collected by the datalogger. The Data Wizard is used to perform multiple data compensations, including barometric compensation, manual data adjustments, and parameter adjustments. The Conductivity Cal tab is used to calibrate the LTC Levelogger Edge.

The Software also includes helpful Utilities. The Diagnostic Utility can be used in case of an unexpected problem. It checks the function, calibration, backup and logging memories, the pressure transducer, temperature sensor and battery voltage, as well as enabling a complete Memory Dump, if required. The Firmware Upgrade Utility allows you to update dataloggers as new firmware becomes available.
