A U-tube manometer with movable branches can be used to measure the expansion of gases at constant pressure. As the heated volume of air expands, the user slides the right branch until the water in the two branches reaches the same height again (p = const.). The increase in the volume can be measured with the scale. It can also be illustrated with arrows. To measure the linear expansion of solid bodies, one end of a metal pipe is securely clamped and the other end rests on a rotating shaft. When steam flows through the pipe, it expands. The displacement of the pointer on the rotating shaft can also be marked with magnetic arrows.
