An instrument for indicating the pressure of any fluid or the difference in pressure between two fluids, whether gas or liquid. [G. manos, thin, scanty, + metron, measure]
- aneroid m. a m. in which the pressure is indicated by a revolving pointer moved by a diaphragm or Bourdon tube exposed to the pressure. SYN: dial m..
- differential m. any device that indicates the difference in pressure between two fluids, regardless of any changes in their absolute pressures.
- mercurial m. an m. in which the varying pressures are shown by differences of elevation in a column of mercury.
