Abstract

See full text

An ultrasonic flowmeter includes flow path that has a rectangular cross section and through which a fluid to be measured flows, and partition plate that divides flow path into measurement flow path and non-measurement flow paths. In addition, the ultrasonic flowmeter includes a pair of ultrasonic sensors that are arranged upstream and downstream of a surface forming flow path and transmitting and receiving ultrasonic signals, and a flow rate calculator that detects a flow rate of the fluid to be measured based on a propagation time. The ultrasonic flowmeter includes openings that connect measurement flow path, non-measurement flow paths, and a space where the ultrasonic sensors is located, and the ultrasonic sensors mainly propagate ultrasonic waves only to measurement flow path through openings.
