A flow meter is used to measure flow rate through a fixed area, like a pipe.
This measurement is usually expressed in terms of volume/time for a volumetric flow rate measurement (such as gpm, or m3/minute).
Industrial settings have a wide range of fluids with very different properties.
There are several different methods available to measure the flow rate of these fluids.
For example, some flow meters are:
The properties of the fluid, along with environmental conditions will determine which flow meter is the best choice to measure a given fluid’s flow rate.
Electromagnetic flow meters have a couple of advantages over mechanical and pressure-based flow meters.
The fluid must be conductive!
