Mopeka Pro Check Sensor — Wireless Propane Tank Gauge
The Mopeka Pro Check Sensor provides a wireless propane gauge that links to a mobile app for real-time level updates. It easily attaches to the underside of propane tanks using strong magnets and ultrasonic sensing to stay in place on uneven terrain. The sensor supports a wide range of LPG tanks from 20 pounds to 120 gallons and 420 pounds, making it versatile for grills, RVs, and larger propane setups. Battery life has been improved for long-term use, reducing the need for frequent replacements.
Mopeka Pro Check Universal Sensor
Designed for North American markets, the Pro Check Universal Sensor offers high-precision ultrasonic readings with up to 99.5% accuracy for various tanks, including propane and water storage. It supports readings for pressurized and non-pressurized tanks and boasts a long battery life that can endure outdoor conditions for years. Note that app compatibility is region-specific, so ensure it aligns with your location and app ecosystem before purchase.
UYZO Water Tank Sensors — 6 Pack
UYZO’s screw-in water tank sensors monitor fresh, gray, and black water levels with durable components designed to resist rust and corrosion. The kit includes multiple parts—grommets, posts, washers, and nuts—allowing flexible installation into RecPro or similar gauge systems. These sensors emphasize sturdy construction for RVs and workplace tanks, making it a practical option for steady, long-term monitoring.
Mopeka PRO+ Long Range Ultrasonic Monitor
The Pro+ model uses long-range ultrasonic sensing to monitor propane tank levels from up to 1000 feet away, with compatibility for tanks up to 2000 gallons. It features a robust RF signal and can be paired with a Wi-Fi bridge to extend monitoring beyond the sensor’s immediate range. This option is ideal for residential and commercial sites where direct line-of-sight monitoring isn’t practical, delivering precise readings via Mopeka’s Co-Pilot app ecosystem.
Long-Range Wireless Automatic Water Level Controller
This system combines a water level sensor with an indoor controller to automate pumping based on tank readings. It supports remote control up to 3 km, includes solar charging, and features multi-functionality such as dry-run protection and sensor error alarms. It’s suitable for outdoor storage tanks, pools, and cisterns where autonomous operation reduces manual checks and improves water management reliability.
RecPro Tank Sensor Monitor Panel M21
The RecPro M21 monitor panel provides a straightforward 12V-powered display for fresh, gray, and black tanks, along with battery voltage monitoring. It’s available in both black and white finishes to match RV interiors and can serve as a reliable replacement or upgrade for older micro-monitor systems, delivering a clear, user-friendly level readout.
Buying Guide: Key Purchase Considerations
- Tank type compatibility: Ensure the sensor supports your tank material, size, and contents (propane vs. water and wastewater). Some sensors are purpose-built for LPG tanks, while others target RV water systems or multi-tank setups.
- Measurement method: Ultrasonic sensors offer non-contact readings and long-range options, while screw-in sensors provide direct tank contact. Choose based on installation ease and environmental exposure.
- Connectivity and ecosystem: Bluetooth, Wi-Fi bridges, and mobile apps vary by model. Verify regional compatibility and whether your preferred app (Co-Pilot, Tank Check, or brand-specific apps) supports your devices and OS.
- Power and maintenance: Battery life, battery replacement needs, and energy efficiency influence long-term reliability. Consider solar charging where outdoor installations are common.
- Mounting and durability: Magnetic mounts are convenient for propane tanks, but ensure magnets hold under vibration and movement. For water tanks, corrosion-resistant materials reduce wear over time.
- Range and monitoring practicality: Long-range models are valuable for large properties or distant tanks. Weigh the benefit of added range against potential setup complexity and cost.
- Installation complexity: Some kits include multiple components (grommets, posts, nuts) requiring basic DIY skills. Others are plug-and-play with minimal mounting.
- Future scalability: If you anticipate expanding monitoring to more tanks or moving to a larger system, pick a model with scalable app support and compatible accessories (bridges, additional sensors).
Across this selection, consumers can compare direct propane tank gauges, universal sensors, and water-tank monitors to match their specific setup. For outdoor or RV use, magnets and rugged enclosures contribute to reliable operation. For larger properties or commercial applications, ultrasonic and long-range options provide broader coverage and smarter automation. Always confirm regional app compatibility and ensure the sensor’s measurement range aligns with your tank capacities before purchasing.
