The Proteus EcoFrog is an innovative, battery-powered ultrasonic level sensor with WiFi connection and free web app for measuring the levels in fuel oil, waste oil, diesel and water tanks. The ultrasonic sensor measures the contents of your tank regularly every 6 hours and transmits measurement data once a day via the WiFi router to a cloud-based data server. Your data can then be displayed free of charge on the web app, which is also optimized for display on mobile devices such as smartphones.
Monitor the level in your heating oil tank and check your consumption via a web portal or on your smartphone:
