Path structure related to flow of fluid to be measured and pressure difference detection in servo type volumetric flowmeter
Abstract:
One pressure difference detection connecting path (71) and another pressure difference detection connecting path (72) are formed so as to be arranged at a predetermined interval in a longitudinal direction. Further, the one pressure difference detection connecting path (71) is formed so as to be connected in front of a continuation center position (70) of a second inflow path (67) and a first inflow path (43). Further, the other pressure difference detection connecting path (72) is formed so as to be connected behind a continuation center position (69) of a second outflow path (66) and a first outflow path (44).
Abstract(Chinese):

一个压力差检测连接路径（71）和另一个压力差检测连接路径（72）形成为沿纵向方向以预定间隔布置。 此外，一个压力差检测连接路径（71）形成为连接在第二流入路径（67）和第一流入路径（43）的连续中心位置（70）的前方。 此外，另一个压力差检测连接路径72形成为连接在第二流出路径66和第一流出路44的连续中心位置69之后。
