Mass Flow Measurement

Volume is a three-dimensional measure of the space a substance occupies.

Volumetric flow is a measure of the amount of volume moving per unit of time. Common units of measure for volumetric flow rate are meters3/minute, liters/minute or feet3/hour.

Density is a physical property which is a measurement of the mass of a known volume.  The density of a substance changes with pressure and temperature.

At high pressure, the molecules of a substance are compressed together, so more mass fits in a given volume. At higher temperatures, on the other hand, the substance expands and less mass fits in a given volume.

See graphs below on the effects of pressure and temperature on density:

Advanced Extraction Systems does not hide flow-rates or use confusing and misleading volumetric flow-rates. All of our systems come with a Coriolis mass-flow meter installed that sends live readings to the HMI panel.
