The transmitter relays data wirelessly to a mains powered
receiver unit, where it is displayed LCD monitor.




Unlike some superficially comparable devices, Apollo Smart’s advanced processing capability
not only calculates the level of fuel inside a tank, but also analyses the
volume of fuel remaining and displays to the user an Estimated Days To Empty.

Additionally, Apollo Smart displays the following information in real time and on demand:

  • Volume of fuel remaining in litres
  • Volume of fuel remaining displayed via bar chart function
  • Number of days supply remaining
  • Internal Air Temperature in degrees Celsius
  • Cold Weather Warning

Optional Apollo Smart App and integral USB connectivity facilitates greater analysis via almost any PC

Reduced energy consumption compared with previous generation electronic oil level monitors

Audible Fuel Theft Alarm option


Fully compliant with all applicable
environmental and technical requirements

The App gives heating oil users the opportunity to analyse documented consumption data, assisting them in better understanding, controlling and managing of heating oil usage and consumption.

Apollo Smart benefits from USB upload technology, which allows energy consumption data to be transferred from the receiver unit to almost any PC via the optional Apollo Smart App.
