The Seelevel display mounts inside the RV.   For convenience, a second display can be installed in the service bay area by the holding tanks.

To purchase an additional display select your current model under the “DISPLAYS ONLY” category.

 

To determine which sender configuration to use for your tanks measure the height of the tank and refer to the following table:

Sender Options Chart

 

 

 

 

 

 

 

SYSTEM SENDERS OPTION:  The SeeLeveL Tank Monitoring System includes 3 x 12” senders.  You can swap any of the 12” senders for optional 6” senders when placing your order.  An additional cost is applied for the 16″ option.

Note:  Do not mix sender types when stacking senders on one tank.

ADDITIONAL SENDER OPTION:  You can also purchase additional senders.  Refer to the following links for the preferred sender detail:

710JS Sender

710ES Sender

710SS Sender

For taller tanks, two stacked 710ES or 710SS senders are used.   

Tanks less than 7 inches in height will require 710JS senders due to better resolution (6″ x 4 = 24 measurements vs the 710ES or 710SS at 16 4 segments X 4).

Holding tanks must be non-conductive material (eg. plastic), system will not work on metal tanks.

Please refer to the manual for complete installation instructions.
