An apparatus for determining the accuracy of a volume of liquid dispensed via a dispenser such as a petrol, liquid gas or diesel pump dispenser. The apparatus comprises a vessel having a narrowed neck portion for reception of a measured volume of liquid from the dispenser. A hollow tubular member can be inserted into the vessel to displace the liquid upwardly. The tubular member has in its side wall a liquid inlet hole. Upon insertion of the tubular member in the vessel upwardly displaced liquid can pass through the hole into the tubular member. Liquid level within the tubular member can be read against a scale tube housed within the tubular member upon withdrawal of the tubular member to indicate the accuracy of the registered volume of fluid dispensed by the dispenser.
