The Mopeka Check Standard Sensor works on 20, 30, and 40 lb (5, 7.5, and 10 gal) DOT cylinders, and on horizontal RV tanks.
Allows you to monitor the level of propane using the free Mopeka Check app on your smartphone or tablet.
Or, propane level can also be monitored with the stand-alone Mopeka Check Double Monitor.
The Mopeka Check app allows connection to multiple sensors, so that you can monitor as many tanks as you want!
The Mopeka Check Standard Sensor can be connected to both the app and standalone monitor at the same time.
