Title:
流量測定装置
Document Type and Number:
Japanese Patent JP7084225
Kind Code:
B2
Abstract:
To provide a flow rate measuring device with which it is possible to prevent the stabilization of gas flow velocity measurement while reducing the device size in a prescribed direction.SOLUTION: A straight tube-type gas meter 1 comprises a gas passage 13 extending in approximately a straight tube lengthwise direction from a gas inflow port 11 to a gas outflow port 12, a flow velocity sensor 5, a measurement cylinder part 4, and a cutoff valve 6. The gas passage 13 includes a bent passage part BP extending in a direction approximately orthogonal to the straight tube lengthwise direction on the upstream side of the measurement cylinder part 4 and having the cutoff valve 6 installed, and a buffer passage part BF formed by extending in the straight tube lengthwise direction from the bent passage part BP and formed by enclosing an upstream end 4a of the measurement cylinder part 4, the bent passage part BP having a bank section BS protruding from a rear wall 1a toward the measurement cylinder part 4 side in a cross section of a plane that includes both of the straight tube lengthwise direction and the extension direction of the bent passage part BP.SELECTED DRAWING: Figure 2
