Industrial flow measurement instruments help monitor the movement of liquids, gases, and steam through pipelines. Different technologies suit different process conditions: turbine meters detect rotor movement, electromagnetic meters measure conductive liquids, and Coriolis meters determine mass flow directly. Thermal mass, vortex, ultrasonic, and positive displacement meters serve other measurement requirements. Selecting a suitable instrument depends on the fluid, flow range, operating conditions, installation, and required accuracy.
