Q

Which of the following is an example of a flow meter which has associated with it a float for flow indication purposes?

🔍 Key Concepts

• Flow meter operating principles – how each type measures flow (mechanical rotation, pressure drop, displacement, etc.) • Float-based indication – which design physically uses a float that moves with changing flow rate • Variable area vs. variable volume meters – how changing cross‑sectional area can be used for indication

💭 Think About

• For each meter type listed, ask yourself: does this design normally have a free‑moving float visible in a tapered tube or chamber? • Think about which meter type is commonly used as a simple visual indicator in clear piping, where the float position directly shows the flow rate. • Eliminate any options that rely mainly on rotation of blades, pressure difference across an orifice, or wobbling/oscillation of a disc rather than a freely moving float.

✅ Before You Answer

• Identify which option is specifically known as a variable area or tapered tube meter using a float. • Confirm that a float rises or falls according to flow rate, balancing fluid drag and gravity. • Verify that the other options instead depend on rotational speed, pressure drop, or positive displacement rather than a float for indication.
