Sender/Sensor Options

The Garnet SeeLevel II senders/sensors are a flexible, self-adhesive printed circuit board that is mounted to the outside of your holding tanks. We offer two sender options. Please check out the images that detail some of this information as well.

• Accuracy: +/- 8% or better, limited by resolution and tank height and shape.
• Sender material: flexible glass epoxy circuit board with conformal coating for circuit protection. Laminated on the back with 3M 300LSE bonding adhesive.
• Resolution: 3/8″ (10 mm).
• Works with all standard plastic RV holding tanks.
  • Will not work with metal tanks.
• Can read liquid levels through plastic tanks up to 3/8″ (10 mm) thick
• Operating Temperature Range: 32 degrees to 140 degrees F.
• Limited 1-year manufacturer warranty.
• Senders can be cut down to size in between each “sensing pad” as long as a minimum of 3x “sensing pads” remain. See the illustration photo.
• The minimum gap between the bottom/top of the tank is 1/4″, however, we recommend that the senders be installed 1/2″ from the top and 1/2″ from the bottom of the tank.
