FLUIDIC FLOWMETER HAVING MICRO-FLOW SENSOR

摘要

PURPOSE:To improve an instrument error characteristic by obtaining an excellent vibration waveform in fluidic element wherein a partition plate is inserted into a nozzle. CONSTITUTION:A partition plate is made to protrude into the upstream side of a throat part 2a of a nozzle 2 and made to expand. Thus, fluid which flows into the nozzle is divided in layer states. The fluid before entering in the nozzle 2 is also divided into layer states. Therefore, the straightening effect in the nozzle is further enhanced, and the excellent vibration waveform is formed. When this flowmeter is applied in a gas meter, the instrument error characteristic can be reduced within one percent.
