Description
描述
A “sonic nozzle” (also known as “Critical Flow Venturis” or “Critical Flow Nozzles”) is a flow meter that can be used as a calibration standard for gas flow meters or any flow measurement device.
“音速喷嘴”（也被称为“临界流文丘里”或“临界流喷嘴”）是一个流量计，可用于气体流量计或流量测量装置的校准标准。
By design, sonic nozzles are a constant volumetric flow meter. However, with the use of a regulated pressure supply, the sonic nozzle becomes a “state-of-the-art” mass flow meter. Considering both the divergent section design and the flow rate, sonic nozzles may operate with an exit pressure as high as 90 of the inlet pressure.
设计，声波喷嘴是一个恒定的体积流量表。然而，随着调节压力的使用，声波喷嘴就变成了一种“最先进的”质量流量计。考虑到不同的截面设计和流量，音速喷嘴可以操作的出口压力高达90的入口压力。
