Flame King 0 90 Ohm Twin Site Remote Dial Gauge for RV ASME Propane Tanks

HOW IT WORKS: It works by varying electrical resistance in proportion to the propane level inside the tank; the resistance range used by the sensor matches the RV tank gauges or monitoring systems RESISTANCE-BASED MEASUREMENT: At full capacity, the sensor will register close to 90 ohms of resistance; at empty, the resistance often drops near 0 ohms; the monitoring system converts this resistance value into a readable fuel level display APPLICATION: 0-90 ohm twin-site gauge is for use with RVs with propane tanks to measure fuel levels Compatible with Flame King Mountable RV ASME Tanks (Models YSN122, YSN203, and YSN293) featuring a screw-on gauge; easy installation; may also fit other tanks equipped with screw-on gauges. CONNECTION TO RV SYSTEMS: This sensor should be wired to a central monitoring panel inside the RV to provide real-time propane level updates for convenient tracking
