Sentinel® Remote Tank Level Monitoring
See Your Tank Levels from Anywhere
The Icon Process Controls LevelPro® Sentinel® is a battery-powered telemetry unit that reads a tank level sensor and sends the level over the mobile phone network. The readings, alarms and history appear on the Sentinel 247™ cloud website, on a computer, tablet or phone.
No mains power, network cabling or internet connection is needed at the tank, and there is nothing to program. The Sentinel powers the level sensor itself.
A Complete Tank Monitoring Package
The Sentinel® pairs with the LevelPro® 100 Series submersible level sensor and fits directly onto the LP100 junction box, or onto the tank with the LB50 mounting bracket. A TVL display can be added for a reading at the tank. These items are sold separately.
It suits chemical suppliers and sites with many tanks: deliveries can be planned from real levels, avoiding emergency fills and wasted trips.
