Kellukemittareissa
Kellukemittareissa, commonly translated as "bell meters" or "bell gauges," are instruments used to measure the presence and concentration of specific gases, often in industrial or laboratory settings. Their operation typically relies on a bell-shaped apparatus submerged in a liquid, usually water. As a gas is introduced and collected within the bell, it displaces the liquid, causing the bell to rise. The degree to which the bell rises, or the volume of liquid displaced, is then calibrated to indicate the volume or concentration of the collected gas.
These devices are particularly useful for measuring gases that are insoluble or only slightly soluble in the
