🔍 Key Concepts

• Differential head (differential pressure) flow measurement and how it relates to Bernoulli’s principle • What a constriction in a pipe does to velocity and pressure of a flowing fluid • Typical primary devices used in differential pressure flowmeters (like orifice plates, nozzles, and Venturi devices)

💭 Think About

• Which option describes a device that narrows the flow area so you can compare upstream and throat pressures to determine flow? • Which of these devices is commonly associated with Bernoulli’s equation and a smoothly contoured constriction in a pipe? • Eliminate any options that measure flow by rotating elements, electromagnetic induction, or vortex shedding, since those are not based on differential head across a constriction.

✅ Before You Answer

• Identify which choice is known as a classic differential pressure / differential head flowmeter primary element. • Confirm that the correct device includes a smoothly converging section, a throat (minimum area), and a diverging section to recover pressure. • Make sure the option you choose is not primarily based on rotation speed, magnetic fields, or counting vortices downstream of a bluff body.
