Overview

The Watchdog Mesh system is a comprehensive, turn-key solution to pipeline integrity management. The patented design features "Wireless Mesh Technology" that virtually eliminates lightning damage to the system. The Watchdog system communicates with one or more wireless "smart node" sensors and/or interruption controllers at a range up to 300 feet.

By providing unparalleled deployment flexibility, users can economically monitor one or more rectifiers at terminals or tank farms, on pipelines and well casings, or on ICCP (impressed current cathodic protection) protected piers and bridge decks. Start with simple volts/amps rectifier monitoring and add GPS synchronized interruption or wireless channels to monitor multiple negative current shunts at any point.

The powerful web interface simplifies multiple rectifier GPS-synchronized interruption, group polling, and automatic compliance report generation.

Applications

• Remote monitoring of rectifiers and test points
• Initiate/schedule group interruption cycles
• Monitor multiple rectifers (tank farms, terminals, multiple negatives) with one Watchdog system
• Monitor valve positions, pressure, tank levels and pumps

Features

• "Wireless Mesh Technology" provides protection from lightning and power surges
• User defined automatic rectifier and test point readings
• Alarm and return to normal notifications via e-mail and/or text message
• GPS synchronized interruption with current sensing
