Magnetic Propane Butane Gas Tank Level Indicator – 4-Pack
Never Run Out of Gas Unexpectedly Again
The eelhoe Magnetic Gas Tank Level Indicator (4-pack) takes the guesswork out of monitoring your propane or butane supply. Using advanced liquid crystal sensing technology, it reads the temperature difference on your tank's surface to display exactly how much gas remains — no shaking, no guessing, no interruptions to your cooking, camping, or BBQ session.
Made in Mainland China.
Key Features
- High-Precision Liquid Crystal Detection: The liquid crystal sensing layer accurately identifies gas levels by detecting surface temperature differences on the tank. Get clear, real-time gas level readings with color-coded indicator bars (green → yellow → orange → red) at a glance.
- Tool-Free Magnetic Installation: A built-in soft magnetic backing adheres instantly to any metal gas tank — no glue, no tools, no residue. Install or remove in seconds, and reposition it freely between tanks.
- Scratch-Resistant PET Shell: The durable PET outer enclosure is waterproof, scratch-resistant, and rated for both high and low temperature environments — from a hot kitchen stove to a cold outdoor campsite. No warping or deformation over time.
- No Batteries, No Power Needed: The PET + liquid crystal + soft magnetic composite structure is completely self-contained. No power supply required — ever. Buy once and use it indefinitely without any loss of detection accuracy.
- Universal Compatibility: Fits most standard propane and butane gas tanks including home kitchen cylinders, outdoor camping canisters, BBQ gas bottles, and RV propane tanks.

Frequently Asked Questions
Q: How does the magnetic gas tank level indicator work?
A: The indicator uses a liquid crystal sensing layer that detects the temperature difference between the gas-filled and gas-empty portions of your tank's surface. The boundary between warm and cool areas reveals where the gas level sits, displayed clearly through color-coded bars — from green (full) to red (low).
Q: Will this indicator work on both propane and butane tanks?
A: Yes! The eelhoe gas level indicator is compatible with most standard propane and butane gas tanks, including home kitchen cylinders, camping canisters, BBQ bottles, and RV propane tanks. It works on any smooth metal tank surface.
Q: Does it require batteries or any power source?
A: No — this indicator is entirely passive and requires zero power. Its PET + liquid crystal + soft magnetic composite construction works on thermal principles alone, making it maintenance-free and reusable indefinitely.
Q: How do I install it on my gas tank?
A: Simply press the magnetic backing against the metal surface of your gas tank. No adhesives, drilling, or tools are needed. It sticks securely and can be removed and repositioned without leaving any residue.
