Sentinel Liner Guard, by Picote

The Sentinel monitors three distinct parts of the lining process: pressure of the liners, power supply and water levels in pumping stations.

The Sentinel features a remote alarm that sends a text message alert via the GSM network to a cell phone should there be a power outage, fluctuation of the pressure outside the limits, or should the water level in a pumping station rise too high. The Sentinel settings are easily adjusted by GSM commands. Pressure data can be requested via text message.
