Flow Sensors are sensors designed to detect and measure the movement of a fluid, such as a liquid or gas, through a system. They convert flow-related changes into an electrical signal that can be monitored, recorded, or used for control functions within electronic and electromechanical equipment.

Within the broader Sensors category, flow sensors are defined by their ability to provide flow information based on physical effects associated with fluid motion. Depending on the sensing principle, they may deliver an analog or digital output and can be integrated into measurement and control architectures.

• Measured media: liquids or gases
• Primary function: flow detection and flow measurement
• Output form: electrical signal suitable for system interfacing
