Description: 1. The YF-S402 is a 1/4 inch water flow sensor designed for measuring and monitoring the volume and velocity of water in various applications. 2. Design: It features a stainless steel body with a threaded connection (BSPP), ensuring durability, resistance to corrosion, and ease of installation in different piping systems. 3. Working Principle: This sensor employs an ultrasonic technology that measures the time it takes for sound waves to travel between two transducers on opposite sides of the flow tube. The resulting data is then converted into a proportional electrical signal using built-in amplifiers. 4. Operating Range and Accuracy: With a measuring range from 0.5 to 12 L/min, this sensor can accurately measure water flow rates in various industrial and residential applications, such as HVAC systems, irrigation, and water treatment plants. 5. Output Signal: The sensor provides an analog voltage output with a linear relationship between the water flow rate and the generated sign
