two-liquid differential manometer
Consists of two concentric glass tubes, each expanded into a large bulb at the upper end. The lower end of the outer tube is sealed, and the inner tube reaches nearly to the bottom of the outer tube. Two liquids are used, and the movement of the interface between the 3421 two liquids down the central tube is used as an index against which the change in pressure is measured.
