摘要： which comprises a plurality of containers (2a, 2b, 2c) having a predetermined internal volume (V1, V2, V3), the volume of at least two of said containers being different from each other, said containers being intended to contain respective amounts of a liquid, wherein each container (2a, 2b, 2c) is provided with a single exhaust nozzle (3a, 3b, 3c) intended to put the internal volume (V1, V2, V3) of said container (2a, 2b, 2c) in fluid communication with an outer environment such to allow said liquid discharged from said nozzle (3a, 3b, 3c) to flow out by gravity in a substantially horizontal direction, each one of said containers (2a, 2b, 2c) further comprising air intake means (4a, 4b, 4c) intended to put the internal volume (V1, V2, V3) in fluid communication with the outer environment in order to define a compensation of the air pressure inside the container, such to make piezometric head constant at the height of said nozzle (3a, 3b, 3c) independently of the change of the liquid level in said container (2a, 2b, 2c) during its emptying, such to obtain a contemporaneous check of the dynamic and volumetric calibration of said catching instruments; a further subject of the invention is a method for carrying out such check.
摘要翻译：它包括容器的多个（2A，2B，2C）具有预定的内部容积（V1，V2，V3），至少两个所述容器的不同于海誓山盟不同的体积，所述容器被用来容纳的respectivement量液体，worin每个容器（2A，2B，2C）设置有一个单一的排气喷嘴（3a，图3b，图3c），用来把内部体积，所述容器的（V1，V2，V3）（2A，2B，2C）流体连通，在外部环境检查，以允许从所述喷嘴喷出，所述液体（3A，3B，3C），以通过重力在基本水平的方向流出，所述容器中的每一个（2A，2B，2C），进一步包括进气口装置（4A，4B，4C），用于把所述内部容积（V1，V2，V3）流体连通的外部环境，以限定容器内部的空气压力的补偿，寻求使测压头恒定在喷嘴的所述高度（图3a，3b，3c）的独立的液体L的变化的伊维尔基尼在所述容器（2A，2B，2C）在其排空时，寻求获得的所述抓取工具的动态和体积校准的同时的检查; 在本发明的另一主题是一种用于执行搜索检查的方法。
