Electromagnetic Flow Meter
Objectives
- Recognize the electromagnetic (mag) flow meter
- Explain the function of the mag flow meter
What's a Flow Meter?
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).
Types of Flow Meters
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:
- Mechanical (a physical component is moved by the flow)
- Pressure-based (uses principles to infer flow rate from pressure differential)
- Electromagnetic (a magnetic field is used to determine flow rate)
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 (AKA Mag Flow Meters)
Electromagnetic flow meters have a couple of advantages over mechanical and pressure-based flow meters.
- They don't restrict flow in any way.
- They can measure dirty fluid containing large particles or thick slurry-type fluids.
But...
The fluid must be conductive!
