  • kõrgusmõõtur, mille puhul kasutatakse mõõteprintsiipi, et vedeliku keemistemperatuur alaneb ümbritseva rõhu vähenemise teel ning et rõhk omakorda sõltub vaatluspunkti kõrgusest
  • hypsometer as shown in the drawing (right) employs the principle that the boiling point of a liquid is lowered by diminishing the barometric pressure, and that the barometric pressure varies with the height of the point of observation
rõhukõrgusmõõtur preferred
Usage examples
  • Rõhukõrgusmõõtur koosneb mantelkolonniga kaetud silindrilisest anumast, milles keedetakse vedelikku, tavaliselt vett, ja mille välimistes vaheseintes aur ringleb, samas kui keskele on asetatud temperatuurimõõtur, ning kõrguse mõõtetulemuse saamiseks vaadeldud keemistemperatuurist on vaja teada keemistemperatuuri ja rõhu vahelist suhet, ning ka suhet atmosfääri rõhu ja kõrguse vahel.
rõhu hüpsomeeter deprecated
Good to know
  • Meeter on pikkusühik.
pressure hypsometer
Usage examples
  • A pressure hypsometer consists of a cylindrical vessel in which the liquid, usually water, is boiled, surmounted by a jacketed column, in the outer partitions of which the vapour circulates, while in the central one a thermometer is placed, and to deduce the height of the station from the observed boiling point, it is necessary to know the relation existing between the boiling point and pressure, and also between the pressure and height of the atmosphere.
