Flow Sensors for Industrial Process Monitoring

Flow sensors are used to measure the flow rate of liquids or gases within industrial processes. Different measurement technologies are applied depending on medium properties, flow range, accuracy requirements, and installation conditions.
Flow measurement is essential for process control, energy management, and system efficiency in automation systems, machinery, and HVAC applications. Selecting the appropriate flow sensor requires careful consideration of pipe size, medium characteristics, pressure loss, and operating environment.
