What is the difference between manometer and Piezometer?

Simple manometer (piezometer) is consisted of only one liquid. It never gives the negative pressure reading. But in differential manometer, two (or three) liquids are used; and pressure difference of two difffferent liquids can be measured conveniently. Also, it is advanced from any other manometer for its feasibility.

Moreover, how is a barometer different from an anemometer?

Wind speed can also be determined by measuring air pressure. (Air pressure itself is measured by an instrument called a barometer.) A tube anemometer uses air pressure to determine the wind pressure, or speed. A tube anemometer measures the air pressure inside a glass tube that is closed at one end.

How a manometer is used to measure pressure?

The resulting pressure is the difference between forces exerted per unit of surface area of the liquid columns, with pounds per square inch (psi) or newtons per square meter (pascals) as the units. The manometer is so often used to measure pressure that the difference in column heights is also a common unit.

What is a manometer and how does it work?

Instruments employing this principle are called manometers. The simplest form is the basic and well-known U-tube manometer. (Fig. 2-1). This device indicates the difference between two pressures (differential pressure), or between a single pressure and atmosphere (gage pressure), when one side is open to atmosphere.
