Ultrasonic flow rate measurement device having inlet side flow rectification part and outlet side coupling part

An ultrasonic flow rate measurement device, comprising:

• a pair of ultrasonic vibrators disposed in a direction such that a propagation path of an ultrasonic wave forms a V-shape relative to a measurement flow path in which a fluid to be measured flows;
• a measurement circuit for measuring a flow rate of the fluid to be measured, by measuring a propagation time of the ultrasonic wave between the pair of ultrasonic vibrators;
• an inlet-side rectification part disposed in an inlet side of the measurement flow path and that stabilizes a flow of the fluid to be measured;
• an outlet-side coupling part disposed in an outlet side of the measurement flow path;
• and
• a signal lead-out part for outputting a flow rate value measured with the measurement circuit;
• wherein the ultrasonic flow rate measurement device is installed by coupling the outlet-side coupling part to an installation structure and the inlet-side rectification part is detached from the installation structure.
