Flow Measurement / Ultrasonic Doppler effect

Principle

The aim of this experiment is to study the relationship between the ultrasonic Doppler effect and the flow velocity or the Doppler angle.

Benefits

• Ideal for teaching the basics of the Doppler effect in fluids

• Experiment setup can be upgraded to perform experiments like flow mechanics and Doppler sonography
• Compact, easy to understand experiment setup

Tasks

1. Measure the frequency shift as a function of the flow velocity and angle of incidence.
2. Use this value to calculate the flow velocity.
3. Represent the frequency shift in graphic form as a function of the pump speed

Learning objectives

• Doppler effect
• frequency shift
• scattering
• Doppler sonography
