Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
5.3.7. TEMPERATURE VOLUME COMPENSATION (ATC).
The TATSUNO EUROPE dispensers for delivering gasoline, diesel and LPG allow conversion of the volume
of dispensed fuel at a given temperature to a corrected volume corresponding to the reference
temperature of 15°C. A precise calibrated temperature sensor Pt100 which measures the current
temperature of dispensed fuel with the accuracy of ±0.15°C is incorporated in the dispenser hydraulic
system before the flow meter. Temperature data from all temperature sensors are collected with the
PDEINP unit located in the counter case and the data is transmitted to the dispenser counter. The
electronic counter automatically recalculates and displays the delivered volume on the display for liquid
fuels or for LPG – see tables below. Fuel density at 15 °C is set in the parameter of the dispenser counter
and must be within the range <700; 1200> for gasoline and diesel and <500;600> for LPG. The temperature
sensor state, PDEINP unit state and density value are checked before each dispensing. If an error is
present, dispensing is not permitted and the error message E10 (sensor), E11 (density) or E12 (PDEINP) is
displayed. The actual fuel temperature measured by the temperature sensor can be displayed in
parameter P14.
