Please note: The Levelogger Junior Edge is now discontinued and has been replaced by the Levelogger 5 Junior.

The Levelogger Junior Edge is made by one of the world's largest manufacturers of water level dataloggers. The Levelogger Junior Edge datalogger measures absolute pressure using a durable Hastelloy pressure sensor which provides excellent performance in harsh conditions and can withstand 2 times overpressure without permanent damage.

This water level datalogger is easy to program using an Optical Reader or PC Interface Cable to connect the Levelogger to a laptop or desktop PC. Deployment is also easily done with Direct Read Cables or wireline/Kevlar cord and the Levelogger locking well cap. It is compatible with all other Levelogger Series accessories.

Using Levelogger Software, programming, downloading, data management and data export are simple tasks with the software automatically detecting the type of logger connected. Live readings can be viewed using the Real Time View Option. Barometrically compensating multiple files can be done using the Data Compensation Wizard and just one Barologger Edge file.

The FRAM memory has an increased storage capacity for 40,000 sets of readings of water level and temperature data points. The user can record at intervals between 0.5 seconds to 99 hours.

Accuracy is 0.1% FS, with 20 bit resolution and lifetime factory calibration.

Water level data from remote Leveloggers can be sent using the model 9500 LevelSender, which uses a GSM cellular modem to send the data to a home computer station or mobile device via email/SMS.
Leveloggers are connected to LevelSenders using a Reader cable which connects to the Levelogger’s Direct Read Cable. This can be done by removing the black dust cap from the LevelSender, lining up the holes and pushing the Reader Cable connector into the LevelSender connection and screwing the Reader Cable into the connection on the LevelSender until tight. Then connect the other end of the reader cable to the top end of the Levelogger’s direct read cable.
Within the diagnostic utility there is an option called ‘read memory dump’ this will access previous logs from a backup location. This dumps all of the Leveloggers memory into a .xle file.

The free app is available on both Apple® and Android™ smart devices.
Apple devices must be running iOS 11 or later on the following compatible devices:

  • iPhone
  • iPad
  • iPad mini
  • iPod touch.

Android devices must be running version 5.0 or higher. Solinst does not guarantee compatibility on all devices running 5.0, but testing confirms the following can be used:

  • Phone: Samsung Galaxy S4 - Model SGH-1337M
  • Phone: Samsung Galaxy S5 - Model SM-G900W8
  • Tablet: Samsung Tab 4 (10.1”) - Model SM-T530NU

As the Levelogger App Interface will not connect directly to the top of a Solinst datalogger, it is necessary to have connection accessories. With the Levelogger or Rainlogger, one of the following accessories is required:

  • Direct Read Cable, clients use this option to suspend dataloggers in the field when they wish to communicate downhole.
  • When working with Leveloggers that are suspended from wireline, or cord, the units must be removed from the well and connected to either a Direct Read Cable (as above) or an Optical Adaptor.
  • For the LevelVent, just connect to the unit via the Vented Cable and LevelVent Wellhead that all units are suspended from in the field – no other connection accessories are required.
  • The AquaVent communication connection is made from the App Interface to the AquaVent Wellhead using an App Connector Cable that is ordered separately.
The Levelogger App Interface is portable hardware that connects to the top of your Levelogger via a Direct Read Cable/Adaptor, to a LevelVent Wellhead, or to an AquaVent Wellhead cable. Bluetooth wireless technology allows communication between the Levelogger App Interface and the smart device with the app installed. It allows viewing/downloading of data, and programming of Solinst dataloggers, as well as many other features.
Solinst offers a wide range of dataloggers that can be used with the Leveloggger App Interface. They include the complete, current Levelogger Edge range of units (Edge, Junior Edge, LTC Edge, Rainlogger Edge), previous Gold Leveloggers/Barologgers, and the latest vented datalogger editions, the AquaVent and LevelVent.
