What type of pressure measurement can differential pressure meters provide?

Differential pressure meters are specifically designed to measure the difference in pressure between two points in a system. This type of measurement is crucial for evaluating flow rates, across filters, or in various HVAC applications, as it helps to understand how pressure drops across components like valves or coils.

When these meters are employed, they can effectively show how much pressure is lost in a process or how fluids are moving through a system, providing valuable insights that can inform maintenance and operational efficiency.

The focus on differential pressure as the correct answer highlights the primary function of these devices, which distinguishes them from other forms of pressure measurement, such as total, static, or dynamic pressure, which serve different purposes in evaluating the overall conditions of a fluid system.
