The Seelevel RV Tank Monitoring System is a state of the art designs for liquid level gauging and monitoring of recreational vehicle holding tanks. The systems come with a variety of capabilities depending on the model and include level measurement, battery voltage, as well as pump and heater switches and pilot out indicators. Each system comes with Garnet's proprietary externally mounted tank sensors for fresh water, grey water, and black water tanks. With nothing inside the tank all the usual problems of corrosion and clogging are eliminated. Individual sensors can measure tanks up to 12 inches tall. For taller tanks, up to 24 inches in height, two sensors can be stacked. The systems are designed with bus style wiring allowing for multiple sensors on a single wire for easy installation using existing wiring and allowing for remote displays to be added to the sewer bay.
