FaraMag™ FM500 mag meter, 20"




The FaraMag™ series of flow meters from H2flow Controls use the electromagnetic principle to measure the flow of conductive liquids. There are no moving parts in contact with the liquid, meaning the flow meter isn’t affected by any solid particles that may pass through the pipe, and there is no resulting pressure drop. The result? With FaraMag™ you will always Know the Flow™!

The FaraMag™ FM500 series mag meter is suitable for a wide range of applications - such as those commonly found in water & wastewater, oil & gas, process manufacturing, aggregate, and pharmaceutical industries, where liquids with a conductivity of ≥10µs/cm are found.
