👉 The term "ceilometer" is a device used to measure atmospheric pressure. It consists of a thin, cylindrical tube with a small hole at its center that allows air to flow in and out of it. The height of this tube is determined by the radius of the cylinder and the diameter of the hole, which determines how much air flows into or out of the cylinder. The pressure inside the ceilingometer is measured using a spring scale, which causes the tube to oscillate as it moves up and
