Title: Method of manufacturing fluidic element, fluidic element, fluidic flowmeter and composite flowmeter
Inventor: IECHI HIROYUKI
IPC: G01F7/00
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To mold a fluidic element by a mold by a method wherein a fluidic vibration in a small flow-rate region is stabilized and a flow-rate measuring region by the output of the fluidic vibration is expanded to the side of the small flow-rate region. SOLUTION: The fluidic element 1A is molded in such a way that the root of a vibration inducing element 7 becomes smooth in order to equally stabilize the division of a fluid spouting from a nozzle 3. Consequently, a change in the exfoliation position at the vibration inducing element 7 of the fluid spouting from the nozzle 3 is small, and the direction of a jet stream is stabilized. As a result, the fluidic vibration in the small flow-rate region is stabilized, and the flow-rate measuring region by the output of the fluidic vibration can be expanded to the side of the small flow-rate region.
