SENDER MANUAL

710-JS  |  710-ES  |  710-SS

The SeeLeveL Senders 710-JS, 710-ES, 710-SS are used with SeeLeveL II 
Tank Monitoring systems that can monitor either two, three or four tanks.

The 710-JS sender is 6" high (not including tabs) and has a resolution of 
1/4".  This model can measure tanks from 5" to 7.5" high tanks and cannot 

be stacked.  The higher resolution is optimal for low-profile tanks. 

The 710-ES sender is 12" high (not including tabs) with a resolution of 3/8" 
and can measure tanks from 5.5" to 14" high with a single sender, and up 
to 26" with double-stacked senders.

The 710-SS sender is 16" high (not including tabs) and has a resolution 
of 1/2".  This model can measure tanks from 7" to 18" high with a single 
sender, and up to 34.5" with double-stacked senders.

The senders are mounted on the outside of the holding tanks and can 

be stacked to fit taller tanks. They work on most plastic or polyethylene 

holding tanks that contain water-soluble fluids.  They are not compatible 

with metal holding tanks.

See more information about sender lengths on page 3.

The communication protocol used between our senders and displays is 
proprietary allowing us to control the accuracy and functionality of our 
systems ensuring our customers experience reliable operation.
