FLOW RATE MEASUREMENT DEVICE

摘要

A flow rate measurement device (1) connected to a home-use gas supply pipe has a flow rate measurement unit (3) for measuring a flow rate at predetermined time intervals, a calculation unit (6) for obtaining a difference in flow rate values outputted from the flow rate measurement unit (3), a device information storage unit (7), and a device determination unit (8) for comparing the magnitudes of both the difference value calculated by the calculation unit (6) and an activation determination value registered in the device information storage unit (7) and determining the use of a device connected to the downstream side of the flow rate measurement unit (3).
