Kenosha, Wis.-based FloCat has introduced the RK20-C electromagnetic flow meter designed to measure the flow of electrically conductive liquids in full pipes. It’s virtually maintenance free because of no moving parts or obstructions in the fluid stream. By being insensitive to changes in specific gravity, viscosity, pressure and temperature, this meter is ideal for measuring difficult fluids like corrosives, slurries and sludges.
