Electromagnetic flow meters are high-precision and high-reliability flow meters. They are used to measure the flow rate of conductive liquids and slurries in closed pipes. They are widely used in industries such as steel, power, petroleum, chemical, coal, metallurgy, mining, papermaking, water supply and drainage,
Vortex flow meters are based on the Karman vortex street theory. They use piezoelectric crystals to detect the vortex frequency generated when fluid passes through a triangular prism inside a pipe, thereby measuring the fluid flow rate. Vortex flow meter can measure liquids, general gases,
