Description: 1. The YF-S201 is a 1/2 inch water flow sensor designed for measuring and monitoring the volume and rate of water flow in various applications. 2. Construction: This sensor features a stainless steel body with an ultrasonic sensor for accurate, non-contact measurement. It operates on DC power (5V-30V) with an output signal of 0-5V analog voltage proportional to the flow rate. 3. Accuracy and Resolution: The YF-S201 offers high accuracy (+/- 3%) and a small flow resolution of 0.2 liters per minute (LPM), making it suitable for applications requiring precise measurement. 4. Applications: Ideal for use in irrigation systems, industrial processes, cooling systems, wastewater treatment, and hydroelectric power generation, among others. 5. Mounting: The sensor can be installed horizontally or vertically using the included mounting bracket, making it versatile for different installation scenarios. 6. Durability: The waterproof design (IP68) ensures protection against water and debris, e
