2.0 LevelSender Overview

The LevelSender is a simple, low cost device designed to wirelessly send data from Solinst dataloggers in the field, via GSM cellular communication, to a Home Station PC, multiple emails and/or an SMS cellular phone number.

 

2.1 LevelSender Remote Stations

LevelSender remote stations are designed to be placed in a 2" diameter well (4" with adaptor), but can also be used in other applications. Each Level Sender comes with a 2" Well Cap Assembly and a Support Hanger Bracket (see Section 6 for installation instructions). LevelSender stations are constructed from PVC, and have an IP rating of 64 (dust and splash proof).

Each station includes a built-in GSM radio module, an antenna, and an LED that flashes with operation. There is a USB connection for programming the LevelSender using the LevelSender PC Software, a compartment for three 1.5V AA replaceable lithium batteries, and a SIM card slot.

Each LevelSender station can connect up to two dataloggers (using a splitter).

Note:

Mini USB Cable for programming the LevelSender, and Reader Cables and Direct Read Cables to connect to Leveloggers are available separately.

2.1.1 LED Light Identification

LevelSender is awake and performing a task.

Startup LED is solid green, then off. If there is an error, the LED will flash red three times.

 

2.1.2 LevelSender Antenna

The Level Sender comes with a SMA male monopole 2dBi antenna. To attach the antenna, simply line up the connector and screw it onto the connection on the top of the LevelSender. The antenna bends to accommodate well cap installation.

The antenna for the LevelSender uses an SMA connection, therefore, you can source other antennas or an antenna cable extension with an SMA male connector, if required.
