Title:
GAS METER
Document Type and Number:
WIPO Patent Application WO/2020/095732
Kind Code:
A1
Abstract:
This gas meter (1) is provided with: a flow rate detection unit (2) for detecting a flow rate value of a gas flowing in a flow path (10); a cutoff valve (4) provided upstream from the flow rate detection unit (2); and a pressure detection unit (3) for detecting a pressure value of the gas, the pressure detection unit (3) being provided downstream from the cutoff valve (4). The gas meter (1) is furthermore provided with a leak detection unit (5a) that assesses whether a gas leak is present downstream from the gas meter (1) on the basis of the flow rate value detected by the flow rate detection unit (2) and the pressure value detected by the pressure detection unit (3). This configuration makes it possible to reliably implement assessment of a gas leak downstream from the gas meter (1) in a short period of time.
