6.1.3 Remote sensor

The remote sensor logs the pressure in the water distribution
network at the end user or critical point. Every 24 hours the
logged data are sent as a text message to the controller via the
GSM network. The data are combined with the data from the
other remote sensors to form a model of the distribution network.
The sensors can be set to give a warning if the pressure drops
below a user-defined limit.

LS42 logger and the XiLog sensor.
