Suburban Mfg 521494 Magnetic Propane Tank Gauge - 10 Pack

The Suburban Mfg 521494 Magnetic Propane Tank Gauge is a simple, tool-free solution for monitoring propane levels in RV, BBQ, and standard LP cylinders. This value-packed 10-piece set is ideal for dealers, service technicians, or RV owners who want to keep multiple tanks monitored at all times.

Each gauge uses temperature-sensitive thermochromic technology to visually display the current propane level. As propane flows and is actively used, the tank wall temperature differs between the liquid and vapor zones—the gauge detects this difference and displays a clear level line, showing exactly how much fuel remains. No batteries, no connections, and no tools are required.

Key Features:

• Temperature-reactive indicator displays propane level while gas is in use
• Strong magnetic backing attaches securely to any standard steel propane cylinder
• Reusable and transferable—move from tank to tank as needed
• No batteries, no wiring, and no tools required for installation
• UV-resistant construction will not fade in sunlight
• Compatible with standard RV, BBQ, and LP propane tanks
• Bulk 10-pack value for service shops, RV dealers, or fleet use

Simply attach the gauge to the lower half of the propane tank on a clean, smooth surface away from weld seams. Turn on your propane appliance and allow gas to flow for several minutes—the indicator will display the fuel level line clearly. The Suburban Mfg 521494 magnetic propane gauge provides a no-hassle, reusable way to prevent unexpected propane run-outs in RVs, campers, and outdoor cooking setups.
