What does volumeter mean?
A volumeter is a technical instrument used to determine the volume occupied by a liquid or gas. It may take the form of a calibrated vessel, a displacement device, or another measuring mechanism suited to the material being tested. The word is especially associated with gas measurement, including laboratory apparatus and industrial or utility systems, but it also applies to instruments for liquids. In context, a volumeter is operated, calibrated, and read much like other measuring instruments: a technician checks the device and interprets its indication of volume. The term belongs mainly to scientific, engineering, and commercial vocabulary and is much less common in everyday speech. It should not be confused with a voltmeter, which measures electrical potential rather than spatial volume. Despite the similarity in spelling, the distinction is fundamental: volumetry concerns the quantity of space occupied by matter, while voltage concerns electrical potential difference. Volumeter is consequently useful in technical writing because it names the instrument, not merely the general act or result of measuring volume.
nounAn instrument used to measure the volume of a liquid or gas.
- An instrument for measuring the volume of a liquid or gas.
"The technician checked the reading on the gas volumeter before starting the experiment."
"The lab used a calibrated volumeter to determine the volume of gas in the chamber."
"The operator checked the liquid level in the volumetric gauge before filling the tank."
The standard plural is volumeters.
"The laboratory calibrated several volumeters before the measurements began."
A voltmeter measures the push of electricity; a volumeter measures how much space a substance takes up.

Etymology of volumeter
Volumeter combines English volume, derived from Latin volumen, meaning a roll or volume, with the measuring suffix -meter, from Greek metron, meaning measure. The formation reflects the instrument's purpose: it measures the volume of a liquid or gas.
