1.5 Inch Water Flow Sensor YF - DN40
1.5 Inch Water Flow Sensor YF-DN40
Overview
Industrial-grade water flow sensor for large pipelines
Designed for 1.5 inch (DN40) pipe systems
Provides real-time flow measurement using pulse output
Suitable for high-flow applications
Working Principle
Water flows through an internal turbine rotor
Rotor spins based on flow speed
Hall-effect sensor detects rotation
Outputs pulse signals proportional to flow rate
Microcontroller calculates flow (L/min or m/h)
