Flow sensors are essential devices used to measure the rate or quantity of a moving fluid, such as liquids or gases, in various industrial and automation applications. These sensors ensure precise monitoring and control of fluid flow, critical for processes in HVAC systems, water treatment, chemical processing, and manufacturing automation. Common types include thermal mass flow sensors, ultrasonic flow sensors, and differential pressure flow sensors. Products in this category may feature high accuracy, robust construction, compatibility with different media, and digital or analog output options. Examples of flow sensors available in the market include inline flow meters, insertion flow sensors, and portable flow measurement devices.
