You’re firing up the grill for a big BBQ, or maybe you’re out camping, relying on propane to keep your RV cozy. Then, the worst happens—the gas cuts out because your propane tank’s empty. I’ve been there, and it’s a total bummer, especially when you’re left with half-cooked burgers or a chilly night. Knowing how to check the gas level in your propane tank can save you from these headaches. Whether you’re grilling, camping, or heating, a propane tank level indicator or a quick trick can keep you in the know. In this guide, we’ll explore the best ways to check your propane tank’s gas level in 2025, compare top tools, and share tips to pick the right one for you. Let’s keep the flames burning!
Why Checking Your Propane Tank Level Matters
Propane powers so much—grills, RV furnaces, patio heaters, and more—but tanks don’t come with a fuel gauge like your car. Running out unexpectedly can ruin a cookout, leave you freezing, or spoil food in an RV fridge. Checking your tank’s gas level helps you plan refills, avoid surprises, and keep things running smoothly. From simple stick-on gauges to high-tech sensors, there’s a method for every budget and setup. Plus, knowing your level can save you from lugging a half-full tank to the refill station.
With tons of tools and tricks out there, we’ll break down the best options, compare top products, and highlight what to consider for your needs, whether you’re a backyard griller or a full-time RVer.
Ways to Check Propane Tank Gas Levels
There are several ways to check your propane tank’s gas level, from high-tech gadgets to low-tech hacks. Here’s the lineup:
- Inline Pressure Gauges: These screw between the tank and regulator, measuring pressure to estimate propane levels. They’re affordable but less accurate in extreme temperatures.
- Magnetic or Stick-On Gauges: These attach to the tank’s exterior and use temperature differences to show fuel levels. They’re cheap and easy but give rough estimates and need propane flow.
- Ultrasonic Sensors: These use sound waves to measure liquid propane levels precisely. Models like the Mopera Pro Tirohia are magnetic and often app-connected 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 isn’t always practical.
- Hot Water Trick: A DIY method where you pour hot water down the tank and feel for a temperature change. It’s free but less reliable and not a long-term solution.
Each method has its place, so let’s compare some top tools for checking propane levels in 2025.

1. DOZYANT Propane Tank Gauge
The DOZYANT gauge is a go-to for budget-conscious users. It’s an inline pressure gauge that fits 5-40 pound tanks with QCC1/Type 1 connections, making it versatile for grills, Rvs, or heaters. The color-coded dial is straightforward, and the leak detector adds a safety bonus. Its brass build is tough, but accuracy can dip in cold weather. At $15, it’s a solid pick for casual grillers or RVers.
2. GASPRO Propane Tank Gauge
The GASPRO gauge offers a bit more precision with a glow-in-the-dark dial and three temperature scales to adjust for weather changes. It’s also brass, fits 5-40 pound tanks, and comes as a two-pack for about $20. Users love its visibility, but its longer stem can be awkward on smaller setups. Great for those who want a reliable, budget-friendly gauge for frequent use.
3. Mopeka Pro Check Sensor
The Mopeka Pro Check Sensor is the high-tech star. This ultrasonic sensor attaches magnetically under 20-40 pound tanks and pairs with a smartphone app via Bluetooth, delivering precise readings. It’s ideal 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 accuracy and convenience are your priorities, this is worth the splurge.
4. Camco Magnetic Gas Level Indicator
The Camco Magnetic Gauge is the simplest and cheapest option. These stick-on strips attach to steel tanks and show fuel levels using temperature differences. At $10 for two, they’re reusable and portable, needing no setup. They’re not very accurate—readings depend on propane flow—but they’re handy for quick checks during a BBQ or camping trip. 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. Ideal for users who prioritize accuracy and don’t mind a bit of effort.
What to Consider When Choosing a Level Indicator
Picking the right method or tool depends on your setup and needs. Here’s what to think about:
- Tikanga: 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: Grilling calls for portable, easy gauges like the DOZYANT or Camco. RV camping or frequent use may justify the Mopeka’s precision.
Extra features can make a difference. Leak detectors (DOZYANT) add safety, glow-in-the-dark dials (GASPRO) help at night, and app alerts (Mopeka) offer convenience.
The Catch with Inline Pressure Gauges
Inline gauges are popular for their low cost and ease, but they have a limitation. 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” quickly. Cold weather can also make the tank seem emptier than it is. If you use an inline gauge, check it regularly, especially when it hits yellow, and don’t expect exact measurements.
Why Ultrasonic Sensors Shine
Ultrasonic sensors like the Mopeka Pro Check are a cut above in 2025. They measure the actual liquid propane level with sound waves, not pressure, making them far more accurate. Their magnetic design is easy to attach or remove, and Bluetooth apps let you monitor levels from your phone—perfect for RVers or grillers who want to stay in the loop. The downside is the cost and occasional battery swaps (coin cell, about yearly). For frequent users, the precision and ease are hard to beat.
The Hot Water Trick: A DIY Backup
No gauge handy? Try this classic DIY method: 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 camping when I forgot my gauge, and it got me through! Use it as a backup and invest in a proper indicator for regular checks.
