Apollo Smart is the world's first tank monitor now with inbuilt Theft Alarm. Unlike traditional tank contents gauges, Apollo Smart allows you to monitor the volume of useable liquid remaining inside your tank, water consumption, costs, air temperature and carbon emissions - from the warmth, comfort and convenience of your home. Measuring key indicators of system efficiency helps you to identify interventions to reduce water consumption, costs and carbon emissions.

Apollo Smart Oil Monitor is a two-piece system, which comprises a tank top transmitter unit and a receiver unit. The wireless transmitter unit is suitable for use with almost any tank up to 3 metres tall, irrespective of manufacturer or material of construction. The receiver unit incorporates a premium quality LCD display and simply plugs into a standard electrical socket, with no wiring or electrical work required.

How It Works

The Apollo Smart transmitter unit can be fitted to almost any tank, with no specialist tools or training required. The unit is simply affixed to the tank via the pre-drilled 32mm diameter aperture, found on most tanks produced in the UK and Ireland since the late 1990s, and retained with 2 self-tappers (supplied). The transmitter unit monitors the level of water inside the tank, measuring water levels and consumption.

This data is transmitted to the receiver unit, which can be positioned up to 150 metres from the receiver unit, where it is analysed and displayed on an intuitive and easy to read display. The receiver unit also benefits from a USB connection, which will allow consumption data to be uploaded to almost any Mac or PC via the Apollo Smart App - available shortly.

The receiver unit also incorporates a unique 'days to empty' facility, which shows you how many days supply of water remains. The risk of running out of water is further reduced by an inbuilt low level alert with audible warning alarm.

For cleaner safer refilling, the Apollo Smart transmitter unit incorporates an inbuilt level display, allowing delivery personnel to monitor tank levels before, during and after delivery.
