SeeLevel 710-ES3 12" Sender

Garnet SeeLevel 710-ES3 Sensor – 12" Flexible Tank Sender

Self-adhesive, external tank level sender for SeeLevel systems. Fits 4.5"–14" tanks (single) and up to 26" with stacked senders.

Overview

The Garnet 710-ES3 is a flexible, self-adhesive printed circuit sender that mounts to the outside of standard plastic RV tanks—no drilling into the tank. This 12" board can be trimmed in 1.33" increments to match your tank height, and multiple boards can be stacked for taller tanks. It works with all SeeLevel 709-series displays and supports multi-tank installations.

Key Features

  • Height Range: Fits tanks 4.5"–14" (single sender), or up to 26" when stacked.*
  • Trim-to-Fit: 12" sender can be cut down to 4" in 1.33" segments for a precise fit.
  • External Mounting: No inside-tank probes—adhere to the outside wall.
  • Multi-Tank: Supports up to 7 tanks (system dependent).
  • Fine Resolution: ~0.33" measurement resolution.
  • Rugged Build: Flexible glass-epoxy PCB with conformal coating and 3M 300LSE adhesive.
  • 709 Compatibility: 710-ES3 works with all SeeLevel 709 systems.

*On 4-tank systems, the gray and galley tanks cannot use stacked senders.

What’s Included

  • (1) 710-ES3 12" sender board (self-adhesive)
  • Wiring pigtail (as supplied)

Installation (Summary)

  1. Confirm tank material (plastic only) and clean the mounting surface.
  2. Trim the sender in 1.33" steps to match tank height (min 4").
  3. Adhere sender vertically; press firmly along full length.
  4. Wire to your SeeLevel harness per the diagram; secure leads.
  5. Calibrate/test on your 709 display and verify readings at 0/50/100% levels.
Fit tip: Route wiring away from heat sources and metal surfaces. The ES3 does not work on metal tanks.

FAQs

Can I stick this on a metal tank?
No. ES3 senders require standard plastic tanks. Metal tanks prevent proper sensing.
How do I know if I need a stacked sender?
If your usable tank height exceeds 14", stack a second ES3 to cover up to 26" total. On 4-tank systems, stacked senders aren’t supported for gray/galley.
Will this work with my 709 display?
Yes—710-ES3 is compatible with all SeeLevel 709-series monitors.
