What are the types of flow meters? Flow meter is a professional automated measuring instrument, whose main function is to measure the flow rate of fluids, including liquids, gases, steam, mixed slurries, solid dust, etc. It is precisely the special role of flow meters that in the field of industrial automation, flow meters and sensors are called the eyes of automation systems. The measurement results are transmitted to the upper computer system, which integrates and analyzes the data, and then applies the preset solutions to the upstream and downstream control systems to achieve intelligent automatic control. Common flow meters include: measuring cleaning liquids such as electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, mass flow meters, orifice flow meters, turbine flow meters, metal rotor flow meters, etc. Measuring gases such as vortex flow meters, V-cone flow meters, orifice flow meters, balance flow meters, waist wheel flow meters (Roots), gas mass flow meters, etc. Measuring steam such as orifice flow meters, vortex flow meters, bend flow meters, etc. Measuring slurries such as electromagnetic flow meters. Users should choose the correct flow meter according to the requirements of the application scenario. Choosing the wrong flow meter will not only affect the project and production, but also cause unnecessary losses to the control system. If you are interested in measuring the flow rate of liquids, you can learn about TSD electromagnetic flow meters, which have high product accuracy and are suitable for various environments. 2.
