Precision accuracy – The SeeLeveL II ™ RV tank monitor provides percentage full, accurate tank measurement readouts. These readouts are accurate within 3/8 of an inch.
Simple to install – Two wires connect to your existing system wires and function on a common bus system. Accessible tanks are easy to retrofit.
Reliable external sensors – Our trouble-free senders adhere externally to the holding tanks eliminating sewage build-up on the sensors.
Customize to fit most tanks – The senders are designed to be easily shortened or two can be combined to accommodate almost any holding tank shape or size. Note: Will work on most plastic or poly holding tanks that contain any water-soluble products. Will not work on metal tanks.
