ULTRASONIC FLOW RATE MEASUREMENT DEVICE

Ultrasonic flow rate measurement device (10) includes measurement flow path (1) in which a fluid to be measured flows, and a pair of ultrasonic vibrators (2, 3) that are disposed in directions such that a propagation path of an ultrasonic wave forms a V-shape relative to measurement flow path (1).

More Information
Summary:Ultrasonic flow rate measurement device (10) includes measurement flow path (1) in which a fluid to be measured flows, and a pair of ultrasonic vibrators (2, 3) that are disposed in directions such that a propagation path of an ultrasonic wave forms a V-shape relative to measurement flow path (1). Moreover, the device includes measurement circuit (4) which measures a flow rate of the fluid to be measured by measuring a propagation time of the ultrasonic wave between the pair of ultrasonic vibrators (2, 3), and inlet-side rectification part (6) which is disposed, in the inlet side of measurement flow path (1), to stabilize the flow of the fluid to be measured. Furthermore, the device includes outlet-side coupling part (7) which is disposed in the outlet side of measurement flow path (1), and signal lead-out part (8) which outputs a flow rate value measured with measurement circuit (4).
