In this guide, we’ll cover the best ways to check your grill’s propane level in 2025, compare top tools, and share a handy DIY hack. Let’s keep those flames roaring!
Why Checking Your Grill’s Propane Level Matters
Propane is the lifeblood of your gas grill, powering those perfect grill marks and smoky flavors. But most tanks don’t have a built-in gauge, leaving you guessing how much fuel’s left. Running out mid-BBQ is a hassle—nobody wants to pause the party to swap tanks or, worse, scrap the meal. Checking your propane level helps you plan refills, avoid surprises, and keep the good times rolling. Whether you’re grilling for a big bash or a quiet family dinner, a level indicator or quick check is a small step that makes a big difference.
With tons of gauges and tricks out there, we’ll break down the best options, compare top products, and highlight what to consider for your grilling setup.
Ways to Check Your Grill’s Propane Level
There are several ways to check the propane level in your grill’s tank, from high-tech gadgets to a classic DIY method. Here’s the lineup:
- Inline Pressure Gauges: These screw between the tank and grill regulator, measuring pressure to estimate propane levels. They’re affordable and easy 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 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 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 can be tricky during a BBQ.
- 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 grilling styles, so let’s compare some top tools for 2025.

1. DOZYANT Propane Tank Gauge
The DOZYANT gauge is a budget-friendly pick at $15. This inline pressure gauge fits 5-40 pound tanks with QCC1/Type 1 connections, perfect for most gas grills. Its color-coded dial (green for full, yellow for low, red for empty) is easy to read, and it includes a leak detector for safety. The brass build is durable, but cold weather can skew readings. Great for casual grillers who want a simple, affordable solution.
2. GASPRO Propane Tank Gauge
The GASPRO gauge offers better accuracy 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 visibility, but its longer stem can be awkward on compact grills. Ideal for frequent grillers who want a reliable, budget-friendly gauge.
3. Mopeka Pro Check Sensor
The Mopeka Pro Check Sensor is the high-tech choice. 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 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 pick.
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. Best for budget grillers 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 a grill. Perfect for grillers who prioritize accuracy and don’t mind a bit of effort.
What to Consider When Choosing a Level Indicator
Picking the right tool depends on your grilling habits 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.
- Grill Setup: Most gauges work with 20-pound tanks and QCC1/Type 1 connections, standard for gas grills. Check tank size limits (e.g., GrillPro is 15-20 pounds) and ensure steel tanks for magnetic gauges.
- Grilling Frequency: Casual grillers can stick with simple gauges like the Camco or DOZYANT. Frequent grillers or BBQ hosts may prefer 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 for busy cookouts.
The Catch with Inline Pressure Gauges
Inline gauges like the DOZYANT and GASPRO are popular for their low cost and ease, but they have a quirk. 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 regularly, especially when it hits yellow, and don’t expect pinpoint accuracy.
Why Ultrasonic Sensors Are a Game-Changer
Ultrasonic sensors like the Mopeka Pro Check are a big deal 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 check levels from your phone—no need to crouch by the grill. The trade-off is the cost and occasional battery swaps (coin cell, about yearly). For frequent grillers or BBQ hosts, the precision and convenience are worth it.
The Hot Water Trick: A DIY Backup
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 I forgot my gauge, and it saved my BBQ! Use it as a backup and grab a proper indicator for regular checks.
