Why Oil Smart®?
Capcitive Technology
The Oil Smart® system uses capacitive sensors that are factory-calibrated for immediate operation to differentiate between oil and water. In contrast to conductive sensors, capacitive sensors are insulated by oil and do not require ongoing maintenance.
Adjustable Alarms
The Liquid Smart® Alarm Sensor can be placed at any predetermined level. Every application is different, and the adjustable alarm allows the sensor to be placed at the actual high liquid level, ensuring that nuisance alarms do not occur.
Adjustable to Any Pump
Not all jobs or applications are equal, which is why Oil Smart® technology allows for the flexibility of being paired with any submersible pump.
No Moving Parts
Unlike other systems that utilize error-prone floats as their primary oil and water sensors, Oil Smart® technology uses reliable solid-state sensors that do not require any moving parts. In addition, See Water’s Oil Smart® sensors have been third-party factory-tested for over 1 million cycles.
Easy Installation
Our capacitive technology allows for hand testing of the sensors, whereas conductive technology requires more steps to test when the system is installed. We offer the only true plug-and-play ® Plug-and-Play System (OSS-100) is the easiest elevator sump pump system to install on the market. With over 25 years of proven field results, Oil Smart® is the preferred solution by environmental specialists and engineers for preventing catastrophic oil spills.
