- Definition: A manometer is a device used for measuring the pressure of liquids or gases. It typically consists of a U-shaped tube filled with a liquid like mercury or coloured water, with the pressure being indicated by the level difference in the two arms of the tube.
- Etymology and Origin: “Manometer” comes from two Greek words: “manos,” meaning “sparse” or “thin,” and “metron,” meaning “measure.” The term reflects the instrument’s function in measuring low-pressure or vacuum conditions. It entered the English language in the early 19th century.
