To choose the right flow meter for process water, you need to know the process water’s chemical compatibility, flow velocity, and potential abrasion in the application. Some chemicals may corrode the flow meter and shorten its lifespan.

Since process flow monitoring usually doesn’t require high accuracy, you probably don’t need an expensive device like a Coriolis flow meter. Vortex or turbine flow meters are also not ideal because the chunkiness of process water can cause clogging. All things considered, the best choice is usually an electromagnetic process flow meter, such as the Picomag.

If the process water contains chemicals, you’ll need a  Teflon liner to prevent corrosion. On the other hand, for water with no chemicals, polyurethane or hard rubber liners work fine.
