SeeLevel Tank Monitors

Accurate and reliable RV tank monitor: Model 709

SeeLevel 709

Features

  • Full features system designed specifically for OEMs
  • 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 up to 12 inches tall with a single sender or 24 inches tall with dual senders
  • Tank sender connect to display via a one wire bus 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
  • Multiple versions meet the needs of differing configurations:
    • 709 – Three Holding Tanks, Battery and LPG Tank
Resolution:3/8 inch (10mm)
Accuracy:± 10% or better, limited by resolution and tank shape
Operating temperature range:0 to +60°C
Sender materials:0.008″ thick glass epoxy circuit board with conformal coating for circuit protection. Laminated on the back with 3M 300LSE Bonding Adhesive
Display mounting panel:Black panel, approximately 102mm wide x 71mm high x 25mm deep. Panel screws to wall. Required cut-out size is 76mm wide x 46mm high
System power requirements:Display requires 12 volts from the RV battery, the system will function from 11 volts to 16 volts. Current drain is less than 200mA
Wiring:Common two wire conductor (signal and ground) required from the display to each sender. 12 V power and ground required for display. Single wire required for LPG sender if sender grounded at tank
LPG sender characteristics:Display will work with an LPG sender maximum resistance of 50 ohms to 500 ohms. Display shows increasing level as resistance increase. System must be calibrated with the LPG tank full, or can be factory calibrated
