DTU Connection with Levelogger

The Levelogger is a water level and temperature recording device. It combines a data logger, 10-year battery, pressure transducer and temperature sensor, in a small, minimal maintenance, 7/8" x 6" (22 mm x 154 mm) stainless steel housing. A engineering company need to deploy numbers of Levelogger in different areas around Hong Kong and get the data from those areas by wireless network.

We provide the RS232 DTU modem in this project. The data from the Levelogger through the RS232 interface of the DTU and transfer the data back to the Telemetry server by the mobile GPRS network. As our DTU modem FD39i transmitting data in the transparent mode transmission, the data from the Levelogger will not have any change during the transmission. It will transfer the Lovelogger data back to the Telemetry server in headquarter.

The users only need to open up the GPRS services with the mobile operator for the SIM card. Then you can collect the data from the Levelogger remotely with the RS232 interface and the GPRS network. A fixed IP address will be assigned to each of the DTU in order to let the DTU to transfer the data back to the server by the mobile and internet.


1.    Get connect with the Levelogger remotely to collect the data

2.    Save the cost for setting up the expensive lease line circuit

3.    Fixed IP addresses can be assignned.

4.    Easy to setup

5.    Low cost of ownership
