Product Options


The 9500 LevelSender is a low cost device designed to provide wireless telemetry from Solinst loggers in the field, directly to multiple email addresses and an SMS recipient. Ideal for cutting down time needed to go to site as you can receive data direct to your smart device.

As standard, each LevelSender system has a single connection port for one datalogger. A splitter can be purchased in addition to provide connections for two dataloggers, allowing a Levelogger and Barologger to be installed in the same well.

Each data report sends information on water level, temperature, conductivity, barometric, or rainfall, status updates and battery level.

Operation of the LevelSender

The LevelSender is setup using the LevelSender PC software and a USB connection. Data is collected at the programmed sample rate, and sent to the ‘Home Station’ and email and SMS at the programmed report rate. Dataloggers can also be programmed to record separately in their internal memory.


  • Connect up to two dataloggers on each LevelSender
  • Fits inside a 2” well casing

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.
2.5" x 9.375" (with antenna folded down)
Yes, the LevelSender fits inside a 2” well casing. The dimensions are 2.5" x 9.375" (with antenna folded down).
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.

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.
