What type of flow measuring device would measure totalized flow volume as opposed to an instantaneous flow rate?

Question 1 of 27070

What type of flow measuring device would measure totalized flow volume as opposed to an instantaneous flow rate?

🔍 Key Concepts

• Difference between instantaneous flow rate and totalized (cumulative) flow volume • How positive displacement devices work compared to velocity or differential pressure meters • Typical use of rotameters, Venturi tubes, and turbine meters in process systems

💭 Think About

• Which device inherently counts or traps fixed quantities of fluid passing through it, rather than just sensing speed or pressure at a moment in time? • For each option, ask: does this meter give you a reading at that instant, or does it naturally lend itself to accumulating total volume over time? • Think about household water meters and fuel dispensers: what operating principle do they usually rely on to show total gallons used?

✅ Before You Answer

• Identify which options are primarily rate-measuring (instantaneous) devices • Identify which option measures flow by repeatedly filling and emptying known volumes • Confirm which principle is commonly used in utility billing meters (total consumption over time)
