Sentinel Liner Guard

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

What our customers say
Arnar Hreinsson
Oliner, Iceland

"Just want to say the Picote Sentinel is a fantastic product. We at Oliner System Iceland forgot two liner right before the holidays and it was guarded by the sentinel the whole time. I would say that the liners are cured."
