ULTRASONIC FLOW RATE MEASUREMENT DEVICE

摘要

An ultrasonic flow rate measurement device (10) is provided with a measurement flow path (1) through which a fluid to be measured flows, and a pair of ultrasonic vibrators (2, 3) mounted to the measurement flow path (1) in directions such that the propagation path of ultrasonic waves forms a V shape. The ultrasonic flow rate measurement device is further provided with a measurement circuit (4) for measuring the propagation time of the ultrasonic waves between the pair of ultrasonic vibrators (2, 3) to measure the flow rate of the fluid to be measured, and an entrance-side rectification part (6) provided on the entrance side of the measurement flow path (1) to stabilize the flow of the fluid to be measured. The ultrasonic flow rate measurement device is further provided with an exit-side connection part (7) provided on the exit side of the measurement flow path (1), and a signal extraction part (8) for outputting the value of the flow rate measured by the measurement circuit (4).
