Document Type and Number:
WIPO Patent Application WO/2011/052241
Kind Code:
A1
Abstract:
Disclosed is a flow rate measurement device that improves accuracy in identifying appliances, simplifies computations and reduces memory usage required for computations, and absorbs variations in flow rate that changes in various ways depending on the state of usage of the appliance, by way of a configuration that extracts characteristics of appliances. The device identifies gas appliances (13, 14, 15), the appliance characteristics thereof varying depending on the state of usage of the appliance, by monitoring and evaluating the change in flow rate as measured by a flow rate measurement means (104), and extracting and evaluating the code that is acquired by a differential conversion means (112) and the characteristic appliance flow quantities that denote the characteristics of the gas appliances (13, 14, 15).
