Title:
FLOW RATE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/155215
Kind Code:
A1
Abstract:
Disclosed is a flow rate measuring device wherein a control means (7) causes a temperature measuring means (8) to singly measure the temperature of a fluid. A flow rate correcting means (6) calculates the temperature of the fluid from the propagation time, and corrects the flow rate using the temperature calculated from the propagation time when the temperature is not measured by the temperature measuring means (8). Consequently, when the measured flow rate is corrected to a flow rate at a desired temperature, higher-precision flow rate correction or improved versatility of a fluid to be measured, and lower power consumption can be achieved.
