What is working principle of manometer?

A manometer works on the principle of hydrostatic equilibrium and is used for measuring the pressure (static pressure) exerted by a still liquid or gas. Hydrostatic equilibrium states that the pressure at any point in a fluid at rest is equal, and its value is just the weight of the overlying fluid.

How the pressure is measured in modern wind tunnels?

In modern wind tunnels, manometers have been replaced by pressure transducers and electrical digital displays for reading pressures and pressure differences.
