INTRODUCTION
These SeeLeveL Senders are used with SeeLeveL Tank Monitoring systems
that can monitor up to seven tanks, including 2 Fresh, 3 Grey, and 2
Black. The senders are mounted on the outside of the holding tanks and
can be stacked to fit taller tanks. Depending on tank height and desired
resolution, Garnet offers three different sender options. They work on
most plastic or polyethylene holding tanks that contain water-soluble
fluids and are not compatible with metal holding tanks.
The 710-AR2 is 9" high. The higher resolution is 0.25" which is optimal for
low-profile tanks. This sender is ideal for tanks 3.5"-11" tall but can be
stacked with an additional 710-AR2 to measure tanks as tall as 11".
The 710-ES3 sender is 12" high. It has a resolution of 0.33" and is the
most popular option, designed to measure liquid levels in most standard
holding tanks. It is ideal for tanks 4.5"-14" tall but can be stacked with an
additional 710-ES3 to measure tanks as tall as 26".
The 710-SS2 sender is 16" high. It has a resolution of 0.44" designed for
taller tanks. It is ideal for tanks 7.5"-18" tall but can be stacked with an
additional 710-SS2 to measure tanks as tall as 34".
