This is the mercurial barometer; another, the aneroid barometer, invented by Monsr.
The atmospheric pressure by the aneroid barometer was at 29.83.
Pity that I had no aneroid barometer for ascertaining the elevation of that site.
Potain modified the apparatus by using air in the bulb with an aneroid barometer for recording the pressure.
It was three miles to the bottom of the gully, and the aneroid barometer registered one thousand one hundred and ninety feet.
The altimeter, which is an aneroid barometer, outlines with fair accuracy the height above the ground at which a plane is flying.
I had still strength to tap the aneroid barometer to facilitate the movement of the needle.
The pressure at the surface of Mars will therefore be 2·1 lb.; and the aneroid barometer would read 4·3 inches.
Got a little doodad out of his pocket; aneroid barometer, or something, he said it was.
In most countries it must be done by reading feet on an aneroid barometer, set with zero of level scale to 30 ins.
A barometer consisting of a thin elastic disk covering a chamber that contains a partial vacuum. High atmospheric pressure pushes against the disk and causes it to bulge inward, while low pressure does not push as hard, allowing the disk to bulge outward. An aneroid barometer is smaller and more portable than a mercury barometer and, when used with a barograph, can record up to a week's worth of data. Aneroid barometers are used extensively in aviation as part of altimeters.
