Title:
FLOW RATE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/110034
Kind Code:
A1
Abstract:
A gas meter (100) which serves as a flow rate measurement device is provided with: a flow rate measurement unit (104) for measuring at regular time intervals the flow rate of gas flowing through a flow passage; a pressure measurement unit (132) for measuring the pressure of the gas within the flow passage; an electric power supply unit (134) for supplying electric power to the pressure measurement unit (132); and an appliance identification unit (116) for identifying, on the basis of the flow rate value of the gas, an appliance being used. The gas meter (100) is further provided with a measurement interval control unit (138) which, on the basis of both the flow rate value of the gas and operating information from the appliance identification unit (116), identifies a state in which gas is not being used, a state in which appliance identification is being performed, and a state in which appliance identification is not being performed. Then the measurement interval control unit (138) controls the electric power supply unit (134) on the basis of each of the states and changes the intervals of on and off of electric power supplied to the pressure measurement unit (132).
