How to Check the Level in Your Propane Tank in 2025: Top Tools and Tips
You’re ready to grill some steaks or heat up your RV for a cozy camping night, but then—poof—the propane runs out. It’s the worst, right? I’ve been stuck with a cold grill and hungry friends more than once, and it’s no fun. Checking the level in your propane tank can save you from these moments, ensuring you’ve got enough gas to keep things cooking or warm. Whether you’re a backyard BBQ champ, an RV road-tripper, or just keeping a patio heater going, there’s a tool or trick to track your propane. In this guide, we’ll cover the best ways to check your propane tank level in 2025, compare top gauges, and share a handy DIY hack. Let’s make sure you never run dry again!
Why Checking Your Propane Tank Level Is a Big Deal
Propane fuels so much—grills, RV furnaces, water heaters, and patio warmers—but tanks don’t come with a fuel gauge like your car. Running out unexpectedly can kill a cookout, leave you shivering, or spoil food in an RV fridge. Knowing your tank’s level helps you plan refills, avoid mid-use surprises, and save trips to the refill station with a half-full tank. From cheap stick-on gauges to high-tech sensors, there’s a method for every budget and lifestyle. Plus, it’s a small step that brings big peace of mind, whether you’re grilling for a crowd or camping off-grid.
With plenty of options out there, we’ll break down the best tools and tricks, compare top products, and highlight what to consider for your setup.
Ways to Check the Level in Your Propane Tank
There are several ways to check your propane tank’s level, from gadgets to a classic DIY trick. Here’s the rundown:
- Inline Pressure Gauges: These screw between the tank and regulator, measuring pressure to estimate propane levels. They’re affordable and easy but less accurate in extreme weather.
- Magnetic or Stick-On Gauges: These attach to the tank’s exterior and use temperature differences to show fuel levels. They’re cheap and simple but give rough estimates and need propane flow.
- Ultrasonic Sensors: High-tech and precise, these use sound waves to measure liquid propane. Models like the Mopeka Pro Check are magnetic and often pair with apps for remote monitoring.
- Weight-Based Scales: These measure the tank’s weight to calculate propane levels. They’re accurate but require lifting the tank, which can be tricky in some setups.
- Hot Water Trick: A DIY method where you pour hot water down the tank and feel for a temperature change. It’s free but not reliable for regular use.
Each method suits different needs, so let’s compare some top tools for checking propane levels in 2025.

1. DOZYANT Propane Tank Gauge
The DOZYANT gauge is a budget favorite at $15. This inline pressure gauge fits 5-40 pound tanks with QCC1/Type 1 connections, perfect for grills, RVs, or heaters. Its color-coded dial (green for full, yellow for low, red for empty) is easy to read, and it has a leak detector for safety. The brass build is sturdy, but cold weather can mess with accuracy. Great for casual users who want a simple, affordable option.
2. GASPRO Propane Tank Gauge
The GASPRO gauge offers more precision with a glow-in-the-dark dial and three temperature scales to adjust for hot or cold conditions. It’s also brass, fits 5-40 pound tanks, and comes as a two-pack for about $20. Users love its clarity, but its longer stem can be awkward on compact setups like small grills. Ideal for frequent users who want a reliable, budget-friendly gauge.
3. Mopeka Pro Check Sensor
The Mopeka Pro Check Sensor is the high-tech pick. This ultrasonic sensor sticks magnetically under 20-40 pound tanks and syncs with a smartphone app via Bluetooth, giving precise propane level readings. It’s perfect for RVers, campers, or serious grillers who want real-time updates. At $80, it’s pricier and requires a phone, with a coin cell battery that lasts about a year. If you value accuracy and convenience, this is a top choice.
4. Camco Magnetic Gas Level Indicator
The Camco Magnetic Gauge is the cheapest and simplest option. These stick-on strips attach to steel tanks and show fuel levels using temperature differences. At $10 for two, they’re reusable, portable, and need no setup. They’re not very accurate—readings depend on propane flow—but they’re great for quick checks during a BBQ or camping. Best for budget users who want a no-fuss solution.
5. GrillPro Propane Gas Level Indicator
The GrillPro Propane Scale is a weight-based gauge that’s highly accurate. You hook it onto a 15-20 pound tank, lift, and read the dial—no installation needed. At $15, it’s portable and precise, but lifting the tank can be a hassle, especially if it’s secured in an RV or grill. Perfect for users who prioritize accuracy and don’t mind a bit of effort.
What to Consider When Choosing a Level Indicator
Picking the right tool or method depends on your needs and setup. Here’s what to keep in mind:
- Accuracy: Ultrasonic (Mopeka) and weight-based (GrillPro) gauges are the most precise. Inline (DOZYANT, GASPRO) and magnetic (Camco) gauges give rougher estimates, especially in cold weather or low gas flow.
- Budget: Magnetic and inline gauges cost $10-20, scales around $15, and ultrasonic sensors $80+. Choose what fits your wallet.
- Ease of Use: Magnetic gauges stick on, inline gauges screw on, and ultrasonic sensors pair with apps. Scales require lifting the tank, which can be inconvenient.
- Compatibility: Most gauges work with 20-pound tanks and QCC1/Type 1 connections, standard for grills and RVs. Check tank size limits (e.g., GrillPro is 15-20 pounds) and ensure steel tanks for magnetic gauges.
- Use Case: Casual grilling calls for simple gauges like the Camco or DOZYANT. RV camping or frequent use may justify the Mopeka’s precision.
Extra features can add value. Leak detectors (DOZYANT) boost safety, glow-in-the-dark dials (GASPRO) help at night, and app alerts (Mopeka) offer convenience for busy users.
The Quirk of Inline Pressure Gauges
Inline gauges like the DOZYANT and GASPRO are popular for their low cost and ease, but they have a catch. Propane tanks maintain steady pressure until the liquid propane is nearly gone, so the gauge might show “full” (green) for most of the tank’s life, then drop to “yellow” or “red” fast. Cold weather can also make the tank seem emptier than it is. If you use an inline gauge, check it often, especially when it hits yellow, and don’t expect super-precise readings.
Why Ultrasonic Sensors Are a Game-Changer
Ultrasonic sensors like the Mopeka Pro Check are stealing the spotlight in 2025. They measure the actual liquid propane level with sound waves, not pressure, so they’re far more accurate. Their magnetic design makes them easy to attach or remove, and Bluetooth apps let you check levels from your phone—perfect for RVers or grillers who want to stay in the loop. The trade-off is the cost and occasional battery swaps (coin cell, about yearly). For frequent users or off-grid campers, the precision and ease are worth it.
The Hot Water Trick: A DIY Lifesaver
No gauge on hand? Try this classic DIY trick: pour a cup of hot tap water (not boiling) down the side of your tank and feel the metal. The part with liquid propane will stay cool, while the empty part warms up. It’s not as reliable as a gauge—results vary with tank size and weather—but it’s free and works in a pinch. I’ve used this when my gauge was buried in camping gear, and it got me through a weekend. Use it as a backup and grab a proper indicator for regular checks.
