1 inch Water Flow Sensor YF-G1 DN25

1 inch Water Flow Sensor YF-G1 DN25 

The YF-G1 (DN25) is a 1-inch inline water flow sensor designed to accurately measure the flow rate and total volume of water moving through a pipe with a 1-inch (DN25) connection. It incorporates an internal turbine rotor that spins as water flows through the body. A Hall-effect sensor detects each rotation of the turbine and generates a digital pulse output proportional to the flow speed. By counting these pulses with a microcontroller, controller board, or monitoring system, you can calculate how fast the water is flowing and how much water has passed through over time. The compact design and simple interface make this sensor ideal for water monitoring, pump control, irrigation, and home or industrial automation applications.
