OPW’s patented SiteSentinel® multi-drop technology, available on the SiteSentinel® Integra100/500™ and SiteSentinel® Nano® tank gauges, saves fuel site operators time and money through an efficient installation design. Because the multi-drop technology enables multiple probes to be run back to a gauge on one wire, the amount of wire and labor needed to install a tank gauge is drastically reduced. This decreases installation costs and site downtimes. A typical 3-tank, 4-dispenser island installation can achieve cost savings of 40 percent.
