Title: Fluidic gas meter
Inventor: NUKUI KAZUMITSU
IPC: F16K31/126
Filed: 1994-06-02
Abstract: PURPOSE:To measure the quantity of gas accurately with a pressure drop within an allowable limit regardless of fluctuation in the pressure on the inlet side of a gas meter. CONSTITUTION:The fluidic gas meter comprises a fluid oscillation element 14, a narrow channel 21 disposed on the upstream side therefrom, and a pressure fluctuation eliminating member 13 having a movable valve 23 and a valve seat 24 operable integrally with a diaphragm 22. Gas pressure P2 on the inlet side of the fluid oscillation element section 14 acts on one side of the diaphragms 22 and the movable valve 23. The movable valve 23 is operated to decrease the open areas of the movable valve 23 and the valve seat 24 as the quantity of passing gas decreases using the pressure difference across the fluid oscillation element section 14 produced depending on the quantity of passing gas. In a low flow rate range where the measurement accuracy is affected by fluctuation in the gas pressure P1 on the inlet side, the gas is passed through the narrow channel 21 to attenuate the fluctuation width of the gas pressure P1 to a level having no effect on the measurement accuracy while sustaining the pressure drop below a level allowable for the gas meter.
