| 摘要 | An apparatus (1) 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 (1) comprises a vessel (2) having a narrowed neck portion (20) for reception of a measured volume of liquid from the dispenser. A hollow tubular member (5) can be inserted into the vessel (2) to displace the liquid upwardly. The tubular member (5) has in its side wall a liquid inlet hole 10. Upon insertion of the tubular member (5) in the vessel (2) upwardly displaced liquid can pass through the hole (10) into the tubular member (5). Liquid level within the tubular member (5) can be read against a scale tube (15) housed within the tubular member (5) upon withdrawal of the tubular member (5) to indicate the accuracy of the registered volume of fluid dispensed by the dispenser. | ||||||
