Abstract: A measuring vessel (1) for determining the accuracy with which a liquid fuel dispenser dispenses liquid fuel comprises a neck (4) of transparent material. A primary arcuate panel (16) having three primary graduated scales (14) corresponding to three different kinds of liquid fuels is secured to the neck (4). Primary graduations (17) of the respective primary graduated scales (14) indicate the level to which the meniscus of actual volumes of the respective liquid fuel dispensed at the temperatures corresponding to the primary graduations (17) should rise so that the energy content of the actual volumes of the respective liquid fuels dispensed is equal to the energy content of a predefined calibration volume of the corresponding liquid fuel at a predefined reference temperature typically of 15° C.
