Distributed level measurements via the GSM network

Keller AG für Druckmesstechnik has now developed a universal, energy-optimised radio module with integrated data logger. The GSM-2 remote data transmission unit and the free PC software allow you to conveniently observe levels, measurements and trends and monitor limits from the comfort of your office. This applies to groundwater levels, waste water levels and the filling levels of mobile tanks on vehicles. However, it also applies to completely different measurements from appropriate sensors with suitable output signals.

Equipped with energy-efficient electronics and a robust lithium battery (3.9 V/32 Ah), the logger can send the results of 24 measurements to a PC at headquarters for up to 10 years by e-mail, or transfer them to a mobile phone via SMS. The maximum measuring speed is 1 measurement per minute. Two voltage inputs (0 - 2.5 V), 2 digital inputs, a BUS interface (RS 485) for operating up to 5 level sensors or optionally the SDI12 interface for water analysis units make the GSM-2 data logger a universal data acquisition module for wide area measuring networks.
