Buying guide

How to choose

Remote Connectivity

Monitoring propane levels remotely requires specific wireless technology. Options like the Generac 7009 and MyPropane utilize cellular LTE or 4G/5G networks to send real-time data to mobile applications. These systems are ideal for users who need to check fuel status while away from home. Conversely, Bluetooth-enabled devices like the Mopeka Pro Check communicate directly with a smartphone app within a specific proximity range. Choosing between cellular-based remote monitoring and Bluetooth depends on whether you require updates from any location or only when you are near the tank. Ensure your chosen hardware supports the transmission method that best matches your monitoring needs and property layout.

Tank Compatibility

Propane tank gauges are designed for specific tank sizes and types. Some models, such as the Mopeka Pro Check, are engineered for steel LPG cylinders and include spacers for common 20, 30, and 40 lb sizes. Other units like the GasXpert are compatible with 5-40 lb tanks, while the MyPropane monitor supports both above-ground and underground tank configurations. The Flame King Twin-Site gauge is specifically designed for vertical, non-RV tanks using a bolt-on installation. Before purchasing, verify that the sensor or gauge matches your tank's capacity, material, and installation style to ensure an accurate fit and reliable operation.

Power Source and Maintenance

Power requirements vary across propane tank gauges, impacting long-term maintenance. The Mopeka Pro Check operates on a replaceable CR2032 cell battery, necessitating periodic manual replacement. In contrast, the MyPropane monitor features solar charging, which may reduce the need for battery maintenance. Other units may rely on the power source of the connected system or the specific design of the gauge. Consider the accessibility of your tank and your willingness to perform battery changes when selecting a monitor. Solar-powered or hardwired options generally offer a more 'set and forget' experience compared to those requiring coin-cell replacements or manual monitoring.

Installation Method

Installation methods differ based on the sensor type and tank design. Magnetic sensors, such as the Mopeka Pro Check, attach to the bottom of the tank, which is useful for portable cylinders. Bolt-on designs like the Flame King offer a more permanent installation for vertical tanks. Cellular monitors like the MyPropane or Generac 7009 units require mounting to the tank exterior to facilitate wireless signal transmission. When evaluating installation, consider if you need a non-invasive solution that does not require tools or a more robust, permanent attachment that remains secure against environmental elements and potential accidental displacement.

Monitoring Features

Advanced monitoring features can provide better insight into propane usage. The Generac 7009 provides real-time alerts via the Mobile Link app, which is particularly beneficial for generator owners aiming to prevent fuel run-outs. The GasXpert offers a mechanical approach with an upgraded three-temperature scale and color-coded indicators for quick visual reference on grills and heaters. If you require precise data, cloud-based apps provide history and alerts, whereas mechanical gauges offer immediate, no-tech feedback. Evaluate whether you need digital notifications or a simple, direct-read dial to manage your propane supply effectively based on your specific equipment and habit preferences.

Common questions

Frequently asked questions

Can I use the Mopeka Pro Check on a tank smaller than 20 lbs?

The Mopeka Pro Check is specifically noted to include spacers for 20, 30, and 40 lb sizes. While it is designed to fit steel LPG cylinders, the provided documentation focuses on these specific weight capacities. It is recommended to verify compatibility with smaller tanks directly, as the sensor requires a flat surface on the bottom of the tank to function correctly. If your tank size falls outside the supported range, the sensor may not provide accurate readings.

Does the MyPropane monitor require a monthly subscription?

The MyPropane monitor is marketed as having no recurring fees. This is a distinct feature for a device that utilizes 4G/5G LTE connectivity for remote monitoring. By eliminating the need for a monthly service contract, this monitor allows users to track their above-ground or underground propane tanks without ongoing costs. Always confirm the current terms of service at the time of purchase to ensure that the no-fee policy remains consistent with the manufacturer's latest product specifications and support offerings.

Will the Generac 7009 monitor work with non-generator propane tanks?

The Generac 7009 is designed as a propane tank fuel level monitor with wireless smart gauge capabilities and Mobile Link app integration. While it is marketed as generator compatible to help users avoid run-outs, its primary function is monitoring propane fuel levels. Provided the tank meets the installation requirements for the monitor, it can be used to track fuel levels for various propane-powered applications. It is intended to offer real-time alerts, regardless of the specific appliance connected to the tank.

How do I read the GasXpert propane gauge?

The GasXpert features an upgraded three-temperature scale and a color-coded interface to indicate fuel levels. This mechanical gauge is designed to be attached to propane tanks ranging from 5 to 40 lbs. By observing the color-coded indicators, users can determine the remaining propane level at a glance. It is a direct-read tool suitable for grills, heaters, fryers, and campers, providing a simple, analog way to monitor your tank without the need for batteries or mobile applications.

Is the Flame King Twin-Site gauge compatible with RV propane tanks?

The Flame King 0–90 Ohm Twin-Site remote dial gauge is explicitly designed for vertical non-RV propane tanks. It uses a bolt-on design, which makes it suitable for stationary tanks rather than those typically found on recreational vehicles. If you are looking for a gauge for an RV-specific system, this model may not be the correct fit. Always verify your tank type and mounting requirements before selecting this bolt-on gauge to ensure it is compatible with your specific propane setup.

Verdict

Bottom line

For users prioritizing comprehensive remote management, the MyPropane monitor stands out due to its 4G/5G LTE connectivity and solar-charging capability, which eliminates recurring fees and battery maintenance. It is the most robust solution for those managing stationary above or underground tanks. For those with portable cylinders, the Mopeka Pro Check offers a reliable Bluetooth-based magnetic solution, provided the user remains within range of the tank. If your goal is to avoid fuel outages for critical equipment like generators, the Generac 7009 is highly specialized for remote alerts. Conversely, for immediate, battery-free visual checks on grills or heaters, the GasXpert provides a reliable, color-coded mechanical solution that requires no complex setup.

Deciding on the best propane tank gauge depends on your specific installation and monitoring goals. If you need remote alerts while away from home, choose a cellular-based monitor like the MyPropane or Generac 7009. If you prefer to check levels via a smartphone while on-site, a Bluetooth sensor like the Mopeka Pro Check is ideal. For those who prefer a simple, non-digital approach, mechanical options like the GasXpert or Flame King are the most straightforward choices. Always match the gauge's mounting style and tank size compatibility to your existing hardware to ensure a secure and accurate monitoring experience.
