Tokheim Automatic Temperature Compensation (ATC)

Request a quote

The Tokheim Automatic Temperature Compensation (ATC) is a fully weights and measures and NMi approved component that ensures you dispense your fuel at the same volume regardless of the temperature. As a rule, the colder the tank temperature the more fuel you may be losing with each sale.

This is because fuel contracts in colder temperatures and expands in warmer temperatures. Many European countries, particularly in the East and Northwest, have a relatively cold average temperature, in which ATC is a component that can provide a clear and transparent return on the investment in your Quantium™ fuel dispenser.

The science behind the technology
  • Let’s take an example of a tank with an average annual temperature of 11.6°C.
  • The temperature co-efficient of fuel is 0.1% per 1°C of temperature change. This means that every time the temperature of the fuel increases/decreases by 1°C it expands/contracts by 0.1%.
  • European legislation allows you to dispense fuel at 15°C. So, your service station would save 0.34%* annually in fuel volume
    (*predicted saving based on 15°C -11.6°C= 3.4°C multiplied by 0.001)
  • A small service station selling 2.5 million litres of fuel per year would save 8,500 litres of fuel
  • With the rising cost of fuel, that’s potentially €15,000 per annum.

ATC Explained

Two options

All new Tokheim Quantium dispensers can be ordered with integrated ATC and retrofit ATC kits can be provided for legacy Tokheim dispensers. These kits are easy to install, and the work can be completed in a few hours by a technician.

Importance of ATC

Fluids such as petroleum are sensitive to temperature fluctuations and as such the volume is directly related to the temperature. In this regard, you want to make sure that you are not losing out annually through temperature fluctuations, as in many cases the delivery from depot truck to station tank is already compensated to 15 °C. ATC provides a fair way of dispensing for both fuel retailers and end customers. The system needs to be 100% reliable.



Tokheim’s stable and reliable ‘mechatronic’ system utilises a robust temperature probe alongside quality tested mechanical parts and our advanced ‘real-time’ pulser electronics are controlled by a powerful software application with sophisticated routines and algorithms. Tokheim’s ATEX certified ATC solution is also applicable for all kinds of fuel products (petrol, diesel, LPG and more).
