Abstract
An ultrasonic flow meter includes measurement flow path where a cross section of a flow path through which a fluid to be measured flows is rectangular, one or more partition plates that divide measurement flow path into a plurality of layered flow paths, and a pair of ultrasonic sensors that are disposed upstream and downstream on the layered flow paths and are capable of transmitting and receiving an ultrasonic signal. In addition, the ultrasonic flow meter includes a flow rate measuring unit that detects a flow rate of the fluid to be measured based on a propagation time, the propagation time being a time period from when one of the ultrasonic sensors transmits the ultrasonic signal to cause the ultrasonic signal to propagate through the fluid to be measured until when an other one of the ultrasonic sensors receives the ultrasonic signal.
