Tanki

Tanki is a remote tank monitoring system that provides accurate ‘real time’ information of the contents of any bulk storage tank – both liquids and solids.
Using the latest mobile phone telemetry, the level of any liquid can be checked anywhere in the world simply by accessing the Tanki mobile app on your mobile phone.
Alerts via your phone’s app inform you of any change in levels immediately alerting you to the change in level.
