Description: 1. The SEN-HZ21WI is a 1/2 inch brass water flow sensor designed for measuring the volume or rate of water flow in various applications. 2. Construction: It features a corrosion-resistant, solid brass body with a threaded connection for easy installation into pipes up to 1/2 inch in diameter. 3. Sensing Principle: The sensor operates using the turbine flow principle, where the water flow rotates an internal turbine that generates an electrical signal proportional to the flow rate. 4. Electrical Characteristics: The sensor outputs a voltage between 0-5V depending on the water flow rate. An integrated temperature compensation circuit ensures accurate readings in various environmental temperatures. 5. Applications: Ideal for use in irrigation systems, swimming pool automation, industrial processes, and water metering applications where precise flow rate monitoring is required. 6. Installation: Easy installation with no moving parts that can wear out or clog – simply connect the sens
