Question restatement: Which of the following meters are pressure differential devices?

Option d: Venturi tube
- A Venturi tube functions as a differential pressure device because it narrows a flowing stream, causing a drop in pressure between the wide section and the throat. By measuring this pressure difference, we can infer the flow rate using principles from Bernoulli’s equation converted for a constriction. This is a classic differential pressure (DP) flow meter arrangement.

Option e: Orifice plate
- An orifice plate is another quintessential differential pressure device. It introduces a sharp restriction in the flow, creating a distinct high-pressure region upstream and a lower-pressure region downstream. The pressure drop across the plate is proportional to the flow rate, allowing measurement via differential pressure.

If we consider other possible meters (not listed here), some devices do not fit the strict definition of a pressure differential meter. For example, a Pitot tube measures stagnation pressure to compute velocity; it is not typically categorized as a DP meter for flow rate in the same sense as Venturi or orifice configurations. It provides a dynamic pressure reading rather than a differential pressure across a single flow restriction used to compute flow directly.

In summary, both Venturi tubes and orifice plates operate on the DP principle: they create a measurable pressure difference that can be translated into flow rate. The reasoning hinges on the relationship between flow, cross-sectional area changes, and pressure via fluid dynamics.
