Sierra 360604002 DTM04 Waste Tank Monitor System with 22" Non-Vented Probe

The Sierra 360604002 is a DTM04 waste tank monitor system designed for marine and RV applications. This complete monitoring solution provides accurate, continuous tracking of waste holding tank levels through an easy-to-read LED panel display and adjustable probe assembly.

Key Features:

• Four-level monitoring with LED indicator lights showing empty, low, mid, and full tank levels
• 22-inch adjustable probe assembly without vent port for tanks with existing ventilation
• Micro-float switch technology provides reliable readings with no false signals
• No electrical components contact waste or water for improved reliability
• 12V or 24V DC operation for versatile power compatibility
• Panel dimensions: 3.25" x 3.25" x 0.375" (extends 2" behind mounting surface)
• Compatible with Dometic SeaLand tanks or any rigid tank with 3-inch FNPT opening

The system includes the DTM04 indicator panel, non-vented probe cap assembly with adjustable 22-inch probes, gasket, and stainless steel mounting hardware. The panel displays only one LED at a time for clear, unambiguous level indication. Optional shutdown relay capability allows automatic toilet shutoff when tank reaches full capacity, preventing overflow situations.

Installation requires a 3-inch female pipe thread (FNPT) tank opening and minimum 2-inch clearance behind the panel mounting surface. For tanks without proper fittings, use Dometic Universal Flange Kit #307230272 (sold separately).
