Accurate Fuel Readings for Your RV Propane System

The Flame King 0-90 Ohm Twin-Site Gauge Sensor delivers reliable, real-time propane level monitoring for your RV's onboard tank system. Designed to work with Flame King Mountable ASME Tanks (Models YSN122, YSN203, and YSN293), this sensor ensures you always know exactly how much fuel you have left.

Precise Resistance-Based Measurement

The sensor operates by varying electrical resistance based on the propane level inside the tank. At full capacity, it registers around 90 ohms, and at empty, it drops near 0 ohms. Your RV's monitoring system converts these readings into an accurate propane level display-so there's no more guessing.

Easy Compatibility and Installation

Engineered for RV propane systems with screw-on gauges, this sensor installs quickly and fits securely. It's fully compatible with most RV tank gauges and monitoring panels, providing dependable performance with simple wiring.

Real-Time Monitoring Made Easy

When connected to your RV's central monitoring panel, this gauge offers instant, at-a-glance fuel tracking, helping you plan refills and avoid unexpected propane shortages during your travels.
