Mopeka Pro Check Sensor
The Mopeka Pro Check Sensor provides a wireless propane gauge that attaches magnets to the underside of the tank. It streams real-time level updates to a smartphone app, enabling monitoring without opening the tank. It is designed for quick installation using strong magnets and supports a wide range of LPG tank sizes, from 20 pounds up to 120 gallons or 420 pounds. Battery life improvements help minimize recharge interruptions, making it suitable for outdoor use and RVs.
Mopeka Pro Check Universal Sensor
The Pro Check Universal Sensor emphasizes high-accuracy readings, offering up to 99.5% accuracy for propane levels in North American markets. It works with the Mopeka Co-Pilot and Tank Check apps, delivering real-time data on pressurized and non-pressurized tanks. The model is built to withstand outdoor conditions, with a battery life of up to five years, ensuring dependable monitoring for grills, water heaters, campers, and RVs.
Mopeka Pro Check Universal Bundle
This bundle includes two Pro Check Universal Sensors and two Tank Halos, enabling simultaneous monitoring of multiple tanks from a single phone. Mounting is quick with magnet-attached sensors and enhanced ultrasonic performance ensures stable readings on bumpy roads or uneven terrains. The bundle supports tanks up to 250 gallons, and the improved battery life extends the period between replacements, making it a practical choice for RV setups and multi-tank configurations.
AP Products 024-1001 Propane Tank Gauge
This indicator uses a magnetic sensor that mounts to the bottom of the LP tank and communicates via Bluetooth for level information. The device is designed for universal compatibility and provides a straightforward magnetic connection, making it easy to install on many standard tanks. It targets users seeking a simple, low-profile gauge option with Bluetooth data access.
Mopeka Pro Check Bundle
This bundle pairs two Pro Check sensors with a dedicated LED display, enabling a dashboard-style readout inside your RV or vehicle. The compact LED display mounts in the dash or control panel and can read levels from two sensors wirelessly. Installation emphasizes reliable magnetic mounting and improved ultrasonic sensor performance, supporting lane-level monitoring for two separate propane tanks in mobile setups.
Buying Guide: Key Purchase Considerations
- Tank compatibility: Consider tank size ranges (20 lb to 250+ gallon) and whether you need single-tank or multi-tank monitoring. Universal sensors and bundles support broader tank types.
- Connectivity and display: Decide between app-based monitoring (Bluetooth, BLE) and in-vehicle displays. LED displays are convenient for dashboards, while smartphone apps offer remote access.
- Installation robustness: Magnetic mounting is common for propane sensors. Ensure magnets are strong enough to resist movement on rough roads and uneven terrain.
- Battery life and maintenance: Look for sensors with long battery life (multiple years if possible) and easy replacement, reducing maintenance frequency.
- Accuracy and alerts: High accuracy (near 99%+) improves reliability. Some models provide continuous updates; others offer configurable update intervals.
- Multi-tank support: If you manage more than one tank (RV, grill, heater), bundles with multiple sensors and optional LED displays simplify monitoring.
- Market restrictions: Some universal sensors are region-specific (North America vs Europe/UK). Verify compatibility for your location.
- Durability: Outdoor exposure, temperature swings, and vibration require rugged housings and weather-resistant sensors.
- Cost of ownership: Consider initial purchase, potential need for LED displays, and replacement battery cycles when evaluating total cost.
