709-RVC SeeLeveL II Tank Monitor
The 709-RVC tank monitor is designed for motorhomes and travel trailers with three holding tanks; fresh, grey, and black tank levels. This model also monitors battery voltage, displays your existing propane (LPG) tank level by connecting to the sensor, and includes an RV-C network interface and a common alarm output which is programmable for level and polarity.
System includes (1) display monitor, (3) tank senders, and (1) pigtail.
Note: For convenience, a second display console can be added to the system by installing it in the service bay area by the holding tanks. Select the “Display monitor only” to purchase.

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.
