Alevel 1x5 sensor is a hardware element of flexible and customized system for LPG distributors developed by AIUT. The system lets the distributors to collect data and convert them into simple and useful information. ,

The sensor that clicks in to standard Rochester R3D® mechanical dials is commonly used on float arm level gauges. It reads LPG level in tanks and sends the data through Sigfox IoT networks. 

Thanks to it the LPG distributors can easily note tank fill and any illegal manipulation on site, such as dial removal, spill detection together with high & low level alerts. 

Current consumption profile and consumption prediction are the key advantages of usage the system.
