Example Sentences

You also get a manometer to monitor pressure and better time your shots.

From Seattle Times

For nearly 400 years, air pressures have been measured using mercury-based instruments called manometers.

From Nature

Moreover, the technique measures pressure directly, using a fundamental constant of nature, meaning metrologists can derive the pascal without relying on previous measurements of other quantities, such as density, which the manometer depends on.

From Nature

Numbers from manometers, measuring the pressures distributed along a wing.

From Literature
