Tank monitor overview · Updated 2 October 2026
Could a tank monitor help you avoid running low?
A tank monitor can make it easier to check your propane or LPG level between deliveries. The useful question is whether a particular monitor fits your tank and how you want to read it.
Start with your supplier and tank
Ask whether your supplier already provides a gauge, remote monitoring or automatic delivery. Confirm whether you own or lease the tank, and whether the supplier permits a third-party sensor. Take note of the tank material, orientation, size and access around its base before comparing devices.
Four things to compare
- Tank compatibility. A magnetic sensor designed for a steel cylinder may not fit an aluminum or composite tank. Some systems require spacers or mounting accessories.
- Connectivity. Bluetooth can suit a tank you visit regularly. Remote readings may require a separate bridge, Wi-Fi or cellular service, plus reliable coverage at the tank.
- Regional version. Check the model for the country where you will use it; apps, radio settings and product availability can differ.
- Ongoing use. Consider battery replacement, app support, alerts and whether the reading is clear enough to act on.
Mopeka Pro Check
Mopeka describes its Pro Check M1017012 as a bottom-mounted, magnetic ultrasonic sensor for steel LPG tanks, with Bluetooth readings in its app. Remote reading needs a separate Wi-Fi bridge. Check the exact model, tank and regional compatibility before buying.
For UK gas cylinders
Truma LevelControl reads compatible steel and aluminium LPG cylinders through an app; LevelCheck provides a handheld check. Truma says these are not for plastic cylinders, refillable gas cylinders or bulk tanks. Magnetic colour-change strips offer a simpler visual check on compatible steel bottles but do not provide app readings. Check the cylinder diameter and any accessories before buying.
For Australian gas bottles
Portable bottle monitors can suit some domestic LPG bottles. Check the local version, bottle size, material and base clearance. A monitor for a portable bottle may not suit a fixed household tank. The product cards alongside this guide search Amazon Australia for models to research.
For New Zealand gas bottles
Start with the bottle size, material, supplier arrangement and whether a monitor will fit beneath it. A monitor for a portable bottle may not suit a fixed household tank. Our New Zealand bottle-level guide covers weighing, magnetic indicators and electronic monitors without sending you to an unaffiliated retailer.
What a monitor does not replace
A level estimate does not confirm delivery timing, tank condition or the safety of any gas equipment. Agree a refill plan with your supplier and use a qualified professional for gas work. If you suspect a gas leak, follow your supplier’s emergency guidance and local emergency instructions.
