11. Glossary

Débitmétrie; Flowmetry

Technique for measuring the flow rate of a gaseous, liquid or solid fluid.

Reynolds (Reynolds number); Reynolds

The Reynolds number is a dimensionless number used in fluid mechanics. It is used to check the range of use of flowmeters according to their principle. It is also used to calculate pressure drops.

Viscosity ; Viscosité

Viscosity refers to the resistance to movement of a fluid during flow. When a fluid's viscosity decreases, its fluidity increases.

Accuracy

Tightness of agreement between a measured value and a true value of a measurand.

Masse volumique ; Density

Mass of product per unit volume.
