What instrument measures liquid volume or capacity?

Answer 1

There are manu instruments capable of measuring liquid volume:

• In laboratories, typical volume measuring devices include graduated cylinders and beakers, and measuring/volumetric flasks. For home use, the equivalents are measuring cups and spoons.
• If you wanted to put a precise volume of a liquid into a jar you might use a burette (a graduated glass tube with a tap at the bottom that you can let exactly the right amount through).
• Or you could use a pipette (a glass tube with a bulge in the middle and a line on the neck. You suck liquid up until it reaches the line and depending on what the size of the pipette is you have an exact quantity.
• A measuring jug or normal scales works millilitres and grams are the same.
• Mathematically, if you know the dimensions of the container of the liquid you can find it's volume and calculate the volume.
• Or you could find the volume indirectly: for example by measuring the time it takes to fill at a known flow rate, or by measuring the mass of liquid and using the density.

They use a graduated cylinder.

Answer 2

That depends on the precision you require, the approximate volume and the purpose of the measurement. In the kitchen I'd use a measuring jug or a calibrated spoon. In the lab, for most purposes I'd use a measuring cylinder of the appropriate size, but for more accurate fixed volumes I'd use a pipette, and for variable volumes a burette or syringe.

Answer 3

Graduated cylinders come in a range of sizes, or volume capacities, and much like a measuring cup, volume is measured by adding liquid to the cylinder and comparing the liquid level to the graduated scale.
