Did you ever wonder how magnetic inductive flow meters work? Check out this animation to learn the secret!
AutomationDirect’s ProSense FMM Series Flow Meters measure flow rates of conductive liquids up to 160 gallons per minute. And the compact low-profile in-line design makes them easy to install and since they have no moving parts they are super reliable. But if there aren’t any moving parts, how do they work? Inside the flow meter there are two coils that create a magnetic field. When the fluid is sitting still, the positive and negative particles are evenly distributed. When the fluid starts to move, the magnetic field forces the particles to separate. The faster the flow, the more the particles separate. The more the particles separate, the more the voltage differential. These electrodes embedded in the side walls are then used to measure the voltage created by the separated particles. And since that voltage is directly proportional to the rate of flow, and the cross sectional area is known, the meter can calculate the total flow. So as long as you have a media with a minimum level of conductivity, these magnetic inductive flow meters from AutomationDirect are a great way to measure flow.
