The Garnet 709-RP Seelevel II Tank Monitoring System is designed for accurate level measurement of motorhomes and trailers with three holding tanks. This system monitors battery voltage, fresh, grey, and black water levels as well as the LPG tank. The level in percent is shown on a three digit LED display. This model includes a 3-way pump switch on the display panel and four analog signal outputs. It is also designed to interface with Monaco’s Aladdin System.

Monitors battery voltage, fresh water tank, grey water tank, black water tank and LPG tank
Provides accurate tank level information using percentage of full readout
Tanks are monitored using Garnet’s proprietary external level sensing technology
- This ends fouling problems caused by debris build-up in the holding tank
- Detailed diagnostic information monitors sender operation
Measures tanks from 5" up to 34" depending on the sensors you specify
Grey and galley water tanks are limited to 12" Tall
Tank senders connect to display via a common bus network topology which saves wiring costs
LPG tank connection compatible with existing electric senders
Calibrate LPG at first fill of tank or it can be factory calibrated
Uses common industry connector for ease of installation and servicing
Utilizes continuous tank level scanning to provide a 0 – 5V output to communicate with the Aladdin System
- This allows replacement of the unreliable pressure sensors used to determine tank level
- The output voltage can be calibrated to match the existing Aladdin display for unprecedented tank level accuracy
Display requires 12 volts from the RV battery, the system will function from 11 volts to 16 volts
Current drain is less than 200mA
